1. Protocol synopsis
Title An Exploratory Pre-treatment Staging and Post-treatment
Assessment in Malignant Lymphoma by Whole Body Diffusion-
weighted MR Imaging (WB-DWI) and ADC-mapping in comparison
to18F-FDG PET/CT
Short title DWI vs FDG PET/CT in Lymphoma
Start and End
Dates of Study
We anticipate the project will run for 12 months (start date
15.01.2010) with an accrual rate of one patient per week. Data
analysis will run concurrently with the data acquisition. The study will
be completed by January 2011.
Study design A single centre non-randomised exploratory study
Number of patients
25 patients in total
Primary
objectives
To prospectively assess the capability of WB-DWI with ADCmapping, relative to integrated fluorine-18 fluorodeoxyglucose (18 F-FDG) positron emission tomography (PET)/computed tomography(CT), in the pre-treatment staging and post-treatment assessment of malignant lymphoma.
Secondary
objectives
(1) To determine whether WB-DWI is sensitive for the pre-treatmentstaging and post-treatment assessment of lymphoma by comparingwith reference test (18F-FDG PET/CT)positive subjects who also testpositive with WB-MRI. Both nodal and extranodal lymphomas arehighly cellular so should be readily amenable to detection by WB-DWI.
(2) To compare the ADC values of lymphoma masses before andafter treatment to determine if patients with lymphoma showingmeasurably lower pre-treatment ADC have a better response tostandard 1st line treatment; and whether effective therapy results inan ADC rise. If this is the case responders and non-respondersmight be identifiable for future treatment stratification.
Primary endpoint The primary outcomes of this study are: 1) to estimate the
percentage agreement in baseline stage for WB-DWI compared to
PET/CT; 2) to estimate the sensitivity and specificity of post-
treatment WB-DWI in detecting response (CR or PR) when
compared to the reference of post-treatment PET/CT.
Inclusion criteria - Age 18 and above- Patients with nodal or/and extranodal lesions at least 2cm in
size- All HD and NHL patients who are undergoing both baseline

Functional imaging with 18F-FDG PET/CT is a valuable tool in the management of
lymphoma, improving staging accuracy and allowing early and more sensitive
assessment of treatment response than conventional methods1-8. 18F-FDG PET/CT does
however show a significant false negative rate in lymphomas with low proliferative
fractions, which show poor FDG uptake∗
; and inflammatory/infective foci may give rise to
false positivity. It also has the limitations of being relatively costly and time-consuming,
and involves patient radiation exposure and associated logistical/radiation protection
issues.
WB-DWI, like PET/CT, is a functional imaging technique, deriving its image contrast from
differences in the diffusion of water molecules within tissues. The degree of water
diffusivity can be quantified by the Apparent Diffusion Coefficient (ADC) calculated using
a range of diffusion weightings. Diffusion correlates inversely with tissue cellularity and
density of cell membranes so that ADC values are low in most tumours relative to normal
tissues. WB-DWI has been used for the detection and characterisation of malignant
diseases (e.g lung9,10 and breast cancers11-13), but has not been applied for tumour
segmentation or the assessment of treatment response. Studies using regional diffusion-
weighted scans have shown that effective tumour therapy results in an increase in
tumour ADC values. Pre-treatment ADC values may also be of prognostic importance
since studies in colorectal carcinoma14,15 and gliomas16,17 have shown that tumours with
lower baseline pre-treatment ADC values responded better to chemo/radiotherapy.
WB-DWI has not previously been applied to the evaluation of lymphoma, but the high
cellularity and cell membrane density of lymphoid tissue has been shown to render it
readily visualizable by the technique and we anticipate that this will make lymphoma
particularly amenable to detection and monitoring by WB-DWI. Accurate and timely
assessment of response to therapy is especially important in lymphoma since a
significant proportion of patients do not respond to first-line therapy and require a promptchange in treatment regimen. Functional imaging with PET/CT has already enabled
objective assessment of metabolic response well before morphological changes become
evident, and we hypothesize that WB-DWI may also prove valuable in this role.
The purpose of this study is to investigate the potential clinical role of WB-DWI in the
detection, staging and assessment of response to therapy in Hodgkin's and non-
Hodgkin's lymphoma, and compare its value to that of 18F-FDG PET/CT in this scenario.
∗
Please note that for the purposes of this exploratory study only cases of high grade NHL
and Hodgkin’s lymphoma. for which 18F-FDG PET/CT is the accepted reference imaging
method, have been included in order to avoid bias due to 18F-FDG PET/CT’s low
sensitivity in low grade NHL. The latter group of patients do not currently undergo routine
clinical PET/CT scanning.
2.1 Background and Rationale for Diffusion Weighted- MR (DWI) Imaging In nodal
disease

8/14/2019 Lymphoma DWI vs PET Protocol (Version4) 08.12.09_ for Ethics
http://slidepdf.com/reader/full/lymphoma-dwi-vs-pet-protocol-version4-081209-for-ethics 11/36
As described above, diffusion-weighted DWI can quantify water diffusion, which is
restricted in highly cellular tissues. The measured apparent diffusion coefficient (ADC)
therefore provides a non-invasive index of cellularity. We will evaluate the potential of
these approaches in the initial staging and post-treatment assessment of lymphoma.
The outcome of the WB DWI scans will be compared to 18F-FDG PET/CT, other imaging
modalities, clinical indices (over 6 months) and histology.
To date, a few small series have shown the potential value of DWI in detecting tumour
foci within lymph nodes through measuring restriction of ADC within nodes18-24.
Stecco A et al. conducted a pilot study comparing the accuracy of 18F-FDG PET/CT and
whole-body DW-I in staging several malignancies. 15 out of 29 patients had malignant
lymphoma. The authors concluded that the whole-body DWI protocol provided a fast
whole-body examination with high specificity and NPV of 98% and 99% respectively 18.
Holzapfel K et al.19 studied 55 enlarged cervical nodes with a small number (n=6) being
due to NHL. They demonstrated that ADC values of malignant lymph nodes weresignificantly lower than ADC values of benign lymph nodes. 94.3% of lesions were
correctly classified as benign or malignant using a threshold ADC value of 1.02x10(-
3)mm(2)/s. This showed that DWI using a SSEPI sequence allows reliable differentiation
between benign and malignant cervical lymph nodes19. King AD et al.20 prospectively
determined the diagnostic accuracy of DWI imaging for discrimination of malignant neck
nodes due to lymphoma, squamous cell carcinoma (SCC), and undifferentiated
nasopharyngeal carcinoma (NPC). The measured mean ADC values for lymphoma (n =
8), NPC (n = 17), and SCC (n = 18) were (0.664 +/- 0.071 [standard deviation]) x 10(-3)
mm(2)/sec, (0.802 +/- 0.128) x 10(-3) mm(2)/sec, and (1.057 +/- 0.169) x 10(-3)
mm(2)/sec, respectively, with significant differences between SCC and lymphoma or
NPC (P < .001) and between NPC and lymphoma (P = 0.04). The study showed thepotential of DWI in differentiating between malignant nodes of SCC, lymphoma, and
NPC using ADC threshold values20. However, DWI and the derived quantitative ADC
values have not been used specifically for the staging and post-treatment evaluation of
residual masses following first line chemotherapy. Organising granulation tissue/fibrosis
is relatively paucicellular, being composed of scattered fibroblasts and inflammatory cells
within areas of collagen deposition, whereas lymphomas are highly cellular tumours. We
hypothesise that on the basis of the available evidence summarised above, DWI should
therefore be an effective modality for discriminating between these causes of a residual
post-treatment mass.
3. Hypothesis
Whole-body DW MR imaging can be used for pre-treatment and post-treatment
assessment in lymphoma patients with accuracy comparable to that of FDG PET/CT
(greater than 70% accuracy). At this small sample size this is necessarily an
exploratory study and further studies based on larger sample sizes will be required to
test the hypothesis more robustly.

4. Study Objectives
• Primary Objective:
To prospectively assess the capability of WB-DWI with ADC mapping, relative tointegrated fluorine-18 fluorodeoxyglucose (18 F-FDG) positron emission tomography
(PET)/computed
tomography (CT), in the pre-treatment staging and post-treatmentassessment of malignant lymphoma.
• Secondary Objectives:
(1) To determine whether WB-DWI is a sensitive imaging biomarker for pre-treatment
staging and post-treatment assessment of lymphoma. Both nodal and extranodal
lymphomas are highly cellular so should be readily amenable to detection by WB-DWI.
(2) To compare the ADC values of lymphoma masses before and after treatment to
determine if patients with lymphoma showing measurably lower pre-treatment ADC have
a better response to standard 1st line treatment; and whether effective therapy results in
an ADC rise. If this is the case responders and non-responders might be identifiable for future treatment stratification.
5. Study Design
A prospective study of patients with newly diagnosed non-Hodgkin's and Hodgkin's
lymphoma prior to and following 1st line chemotherapy. We plan to evaluate the
diagnostic accuracy of WB-DWI in the pre-treatment staging and post-treatment
assessment of lymphoma and compare this with the results of the routine combined
functional and anatomical 18F-FDG PET/CT scans also performed at baseline and at
completion of 1st line treatment.

5.2 Study Methods
5.2.1 Study Population and Method
12
8/14/2019 Lymphoma DWI vs PET Protocol (Version4) 08.12.09_ for Ethics
http://slidepdf.com/reader/full/lymphoma-dwi-vs-pet-protocol-version4-081209-for-ethics 13/36
This is a single-stage exploratory study. Patients will be scanned using 18F-FDG PET/CT
(from vertex to thigh) and WB-DW MRI (from vertex to thigh) one at baseline and 4
weeks after completion of first-line treatment. At baseline independent reviewers blinded
to patient numbers will assess each scan and record the disease stage. At the end of
treatment independent reviewers will asses each pair of scans (baseline and end
treatment) and record the disease response as CR, PR, SD or PD.
25 patients with newly diagnosed histologically proven lymphoma (NHL &HD) with at
least one site of disease measuring > 2 cm in diameter, scheduled to be treated using
standard 1st line chemotherapy, and who consent to take part in the study will be
prospectively evaluated using WB-DWI imaging (from skull base to upper thighs) at
baseline and at completion of treatment (1.5 Tesla WB- DWI:, Echo-planar spin-echo
technique, free breathing, STIR fat suppression, three b-values 0, 300 and 900 s/mm2).
Patients with contraindications to MR or PET imaging will be excluded. As there is no
defined gold standard for lesion detection in lymphoma, WB-DWI findings will be
corroborated with the most sensitive currently available detection method, 18F-FDG
PET/CT. The clinical outcome data will be based on imaging at 6 months by routine
CeCT NCAP, as well as 18F-FDG PET/CT and/or histology if available.
5.2.2 Biomarker Analysis
Study measurements
Differences in mean ADC values between baseline(pre-treatment) and post-treatment
will be documented. ADC values will be calculated on a per patient and a per lesion
basis, to include the largest 5 lesions per patient. The median ADC value will be
recorded for each of the five lesions, and the mean of the medians will be recorded for
each patient. For each patient and lesion the difference in mean/median ADC between
baseline and post-treatment will be calculated. Patients that are alive and free fromprogression at 6 months (primary endpoint) and show imaging evidence of response (CR
or PR) will be considered ‘responders’ and those that either die or progress before then
will be considered ‘non responders’.
(1) WB-DWI and 18F-FDG PET/CT will be independently reviewed and scored by two
radiologists (including one radiologist with additional specialization in nuclear medicine)
for the presence, location, and confidence for suspected lesions. Visual and
semiquantitative assessment using SUV mean and SUVmax will be employed in scoring
the 18F-FDG PET/CT scans (see Appendix 5).
(2) In each patient, the median ADC total for each of the largest 5 lesions present,(calculated using all 3 b-values) and the median high (calculated using b=300 and 900
s/mm 2) for nodal and extranodal lesions will be calculated.
(3) The b=900 s/mm 2 image and ADC values of lymphomatous disease will be used as
a basis for volume segmentation of lymphomatous disease. We will investigate and
define the level of acceptability for lymphomatous disease detection using WB-DWI.
Primary outcome

http://slidepdf.com/reader/full/lymphoma-dwi-vs-pet-protocol-version4-081209-for-ethics 14/36
The primary outcomes of this study are: (1) to estimate the percentage agreement in
baseline stage for WB-DWI compared to PET/CT and show that this is better than
70% (2) to estimate the sensitivity and specificity of post-treatment WB-DWI in detecting
response (CR or PR) when compared to the reference of post-treatment PET/CT.
Secondary outcomes
Secondary outcomes are as follows:
1) To estimate the difference in baseline ADC, and ADC change (baseline to post-
treatment) in responders vs non-responders.
2) To assess the ability of ADC change (baseline to post-treatment) to predict response
at 6 months, where response at 6 months is assessed using PET/CT and histology
(where available).
3) To calculate the per-lesion sensitivity of baseline WB-DWI, using PET/CT as the
reference.
Analysis methods – primary outcomes
Staging agreement will be calculated as the number of patients with the same baseline
stage using PET/CT and WB DW-MRI, divided by the total number of patients. A one-
sided exact biomial test with alpha=0.05 will be used to test the null hypothesis
that agreement is no more than 70%. In addition a Kappa statistic to measure
agreement between these two methods will be calculated.
Sensitivity will be the number of patients declared as CR/CRu/PR using both end of
treatment scans (WB-DWI and PET/CT), divided by the number of patients with
CR/CRu/PR on PET/CT.
Specificity will be the number of patients declared as SD/PD using both end of treatment
scans (WB-DWI and PET/CT), divided by the number of patients with SD/PD on
PET/CT.
Analysis methods – secondary outcomes
Mean per-patient baseline ADC, and change in per-patient mean ADC will be
summarised with descriptive statistics, separately in responders and non-responders. In
an exploratory analysis, a two-tailed t-test (or Mann-Whitney if considered more
appropriate) will be used to compare ADC values in the two groups. This analysis will be
performed twice: once for mean overall ADC (all b-values) and once for mean high ADC
(b-values >100).
A ROC curve will be constructed to assess the sensitivity and specificity of change in
mean (per-patient) ADC in predicting status at 6 months. This analysis will be performed
twice: once for mean overall ADC (all b-values) and once for mean high ADC (b-values
>100).

http://slidepdf.com/reader/full/lymphoma-dwi-vs-pet-protocol-version4-081209-for-ethics 15/36
Per-lesion sensitivity will be measured by recording each lesion detected using PET/CT,
and noting whether or not it was also detected using WB-DWI. The sensitivity will be
calculated as the total number of lesions detected on both scans, divided by the total
number of lesions detected on PET/CT. (In each patient a maximum of 5 lesions will be
recorded)

attending outpatient clinics. They will be given verbal and written information about the
trial and informed that their entry into the study is entirely voluntary. They will then be
given adequate time to consider whether they wish to enter the study or not (a minimum
of 24 hours). Patient recruitment and screening will only commence once the appropriate
official notification has been received by the chief investigator that the trial is open for
recruitment. Study-specific procedures will only commence once the patient has signed
informed consent.
8.2 Consent

http://slidepdf.com/reader/full/lymphoma-dwi-vs-pet-protocol-version4-081209-for-ethics 17/36
Consenting procedures will conform to GCP and local and national regulations. A copy
of the patient information sheet and consent form is given in the appendices to this
protocol. Written informed consent will be obtained for entry into the imaging trial.
8.3 Patient registration
Patients should be registered with the Radiology/Nuclear Medicine Department on the
day of consent for this study or as soon as possible thereafter.
Please contact the Trials Office on + 44 (0)20 8661 3544. Patient eligibility will be
checked at the time of registration and will include the inclusion and exclusion criteria
listed above.
8.4 Subject and drug withdrawal
A patient will be immediately withdrawn from the study if any of the criteria in Section 6.3
are met. Any CRFs will be completed.
8.5 Outcome reporting
All of the patients registered will be accounted for. The outcomes of patients who were
not evaluable or who died or withdrew before treatment began will be specified. The
number of patients lost to follow up will be given and the distribution of follow up time
also given.
8.6 Premature discontinuation of study
The trial management group in conjunction with the chief investigator will review new
published evidence regularly. Premature discontinuation may occur because of a
regulatory authority decision, a change in opinion of the independent ethics committee/
institutional review board, drug safety problems or at the discretion of the Chief
Investigator in conjunction with the CCR. If the trial is prematurely terminated, all study
staff and investigators will be notified by the Principal Investigator. All trial materials and
CRFs must be completed to the greatest extent. Patients already enrolled will continue
to be followed up as per protocol.
9. Study Assessments
Safety reporting for serious adverse events
As this is an exploratory study, no adverse effects are expected from the DW MRI scans.
However any serious adverse events will be reported to the Chief/Principal Investigator
and co-investigators and managed appropriately. The Chief/Principal Investigator has
responsibility to notify the ethics committee.
10. Statistical considerations
17
8/14/2019 Lymphoma DWI vs PET Protocol (Version4) 08.12.09_ for Ethics
http://slidepdf.com/reader/full/lymphoma-dwi-vs-pet-protocol-version4-081209-for-ethics 18/36
Based on an expected level of agreement of 95%, the study will have at least 80%
power to show that the level of agreement is >70%, using a one-sided alpha of
0.05 and an exact binomial test (calculated using nQuery version 6.0).
Agreement in at least 23/25 patients will be required in order to declare that
staging using DW-MRI is acceptable when compared to PET-CT.
11. Ethical considerations
11.1 General ethical issues
This responsible investigator will ensure the study is be carried out in accordance withthe World Medical Association Declaration of Helsinki (1964) and the Tokyo (1975),Venice (1983), Hong Kong (1989), South Africa (1996) and Scotland (2000)amendments, or the laws and regulations of the country, whichever provides thegreatest protection for the patient.
The study protocol will be given approval by the REC (Research Ethics Committee) andwill only be open to recruitment following the approval being granted. Subjects will onlybe allowed to enter the study provided they have given written informed consentfollowing a full explanation of the study and reading of the information sheet (Appendix10 and 11). The patient information sheet may be translated into other languages if necessary.
Subjects will be informed that they have the right to withdraw from the study at any stagewithout prejudice to their further treatment and care and without having to give a reason.This study may be terminated at the request of the Principal Investigator or theIndependent Ethics Committee if during the course of the study concerns about thesafety or efficacy about the proposed treatment emerge. The Principal Investigator willupdate the ethics committee of any new information relating to the trial treatment whereappropriate.
11.2 Informed consent
Written informed consent will be obtained from each patient in accordance withregulatory requirements, GCP and the Declaration of Helsinki. The subject will have theexact nature of the study explained to them (written and verbal), and the anticipatedbenefits and known side-effects. They will be advised that they are free to withdraw fromthe study without obligation. The consent form will also request permission for personnelinvolved in the research to have access to the subject’s medical records.Both the person taking consent and the patient should personally sign and date the form.The original copy of the signed Consent Form must be retained by the Investigator in theStudy File, a copy will be put in the subject’s notes, and a copy of the signed ConsentForm will be given to the subject. Patients will be asked permission to inform their GP of participation within this trial and if they agree, a letter will be sent to their GP (Appendix12).
12. Data handling and Record Keeping
18
8/14/2019 Lymphoma DWI vs PET Protocol (Version4) 08.12.09_ for Ethics
http://slidepdf.com/reader/full/lymphoma-dwi-vs-pet-protocol-version4-081209-for-ethics 19/36
Data will be collected and maintained according to ICH-GCP standards. The data
manager assigned to the study will enter data from the CRFs into a trial-specific
database which will be run off the main HIS database. All source documents relating to
individual research participants will be anonymised and maintained securely within the
hospital (locked room). The computer database is password protected and will hold the
decode for the identification of the patient. Personnel who have access to the database
are legally bound by the confidentiality agreement in their contract of employment.
Source documents will be maintained for 15 years and will be available for inspection by
authorised staff including the Chief/Principal Investigator, Study Coordinator, Clinical
Trials Manager, Research Nurse and statistician. Source documents will be made
available if requested for monitoring and audit purposes to the Ethics and Research and
Development departments and for inspection by regulatory bodies.
13. Quality Control and Quality Assurance
The monitoring processes above will form the mainstay of quality control within thestudy. Laboratory tests are subject to internal validation and standardisation processes.
Imaging will be independently reviewed by one radiologist for the outcome of response
to therapy. Established secure and confidential computerised systems for recording data
are in place. Investigators and study personnel will be made available for possible
audits and inspections by the institutional review board or Ethic Committee and by the
regulatory bodies. All source documentation and the site study file will be available for
inspection.
14. Financing, Indemnity and Insurance
The cost of the WB DW MRI scans will be supported by the Royal College of Radiologists Research Funding Scheme (Small Project Grant) and The RoyalMarsden Radiology Department Research Fund. The usual NHS indemnity processesare in place to cover negligent harm causes through participation in this trial. No costrequired for FDG PET imaging as this is part of patients’ routine clinical management.
15. Publication Policy
The aim of the investigators is to author and publish the mature results of this study in a
peer reviewed journal. All presentations and publications require authorisation from the
Principle Investigator.

ANALYSIS
(Study Title: DWI vs FDG PET/CT in Lymphoma)
The MRI and PET-scans will be analysed visually, semiquantitatively and interpreted by
an experienced reader (the same reader should interpret all scans for each subject). Avisual assessment of the extent intensity and changes in FDG pattern of uptake will berecorded at subsequent visits.
The same lesions (upto 5 target lesions) must be assessed on the follow up and thesame description used as at baseline/follow up scan. The presence of new lesionsshould be recorded.
Lesions should be recorded in the same order at all visits.
Site codes
Nodal sites:
1 = Right cervical nodal sites (levels 1-5) 2 = Left cervical nodal sites (levels 1-5)3 = Right axilla 4 = Left axilla5 = Right hila 6 = Left hila7 = Right mediastinum 8 = Left mediastinum9 = upper retroperitoneum 10 = Lower retroperitoneam11 = mesenteric 12 = iliac chain13 = inguinal/femoral
Extranodal sites:
A = Head and Neck A1 Tonsils A2 Parotids A3 Salivary glandsB = Lung C = Spleen D = Liver E = KidneysF = Stomach G = Pancreas H = Small and large bowelI = Skeleton/Bone marrow J = Others (please specify)
Extent of FDG uptake recorded as follows:
0 = Complete resolution1 = Marked reduction in extent2 = Minor reduction in extent3 = No change in extent4 = Increase in extent
Intensity of FDG uptake:0 = No FDG uptake1 = Marked reduction in intensity2 = Minor reduction in intensity3 = No change in intensity4 = Increase in intensity

18F-FDG PET/CT Data Analysis
PET-CT scans will be reviewed and scored by two named PET/CT specialists, who areblinded to the patient’s clinical status. Visual and semi-quantitative interpretation will beused. Differences in reporting will be resolved by consensus between two doctors or bya third doctor where agreement cannot be reached.
The PET-CT response scans will be scored with reference to sites of presumedlymphomatous involvement on the PET-CT staging scan
Negative
1 no uptake2 uptake ≤ mediastinum3 uptake > mediastinum but ≤ liver
NOTE if mediastinal blood pool activity is equal or greater than liver then the uptakewithin the lesion should be compared with liver (lesion uptake less than liver = score 2;lesion uptake equal to liver = score 3)
Positive
4 moderately increased uptake compared to liver at any site5 markedly increased uptake compared to liver at any siteX new areas of uptake unlikely to be related to lymphoma
Re-assessment and FDG-PET scanning
Reassessment PET-CT scan will be done after the last cycle of chemotherapy.
FDG-PET scan is defined as positive (score 3, 4, 5) and negative (score 1, 2). The
results of this which will be scored on a 5 point scale (1 – no disease; 2 – probably nodisease; 3 – possibly disease; 4 – probably disease; 5 – definitely disease) and further treatment will be determined according to the local protocols and practice.
Definitions
CR - Disappearance of all evidence of disease. (a) FDG-avid or PET positive prior to
therapy; mass of any size permitted if PET negative (b) Variably FDG-avid or PETnegative; regression to normal size on CT.
PR - Regression of measuable disease and no new sites. 50% decrease in SPD of up to
6 largest dominant masses; no increase in size of other nodes (a) FDG-avid or PET
positive prior to therapy; one or more PET positive at previously involved site (b) Variably
FDG-avid or PET negative; regression on CT.

Patient Information Sheet
Title: Pre-treatment Staging and Post-treatment Assessment in Malignant Lymphoma by Whole
Body Diffusion-weighted MR Imaging (WB-DWI) and ADC-mapping in comparison to18F-FDG
PET/CT.
Dear Sir / Madam,
You are invited to take part in a research study. Before you decide to take part it is important that
you understand why the research is being done and what it will involve. Please take time to read
the following information carefully and to discuss it with friends, relatives and others if you wish.
Please take your time to decide whether or not you wish to take part in the study. If you need any
further information or feel that anything is not clear, please ask. This copy of the information sheet
is yours to keep. Thank you for reading this.
The purpose of this study is to assess whether whole-body diffusion-weighted Magnetic Resonance
Imaging (DWI) can be used for pre-treatment and post-treatment assessment of lymphoma patients with
accuracy as good as that of the best currently available technique, PET/CT scanning. Whole-body DWI
scanning is a recently developed imaging technique which has several advantages over PET/CT, one of
the most important being that it does not involve any exposure to radiation and is also quicker to perform.
Why have you been chosen? All patients who will receive chemotherapy as part of their treatment for
lymphoma are being asked if they would like to take part in this study.
Do you have to take part? It is entirely up to you whether or not to take part. If you decide to take part
you will be given this information sheet to keep and be asked to sign a consent form. If you decide to take
part you are still free to withdraw at any time and without giving a reason. A decision to withdraw at
anytime, or any decision not to take part, will not affect the standard of care you receive in the future.
What will happen to you if you take part? Everyone who agrees to take part will have a whole body
Magnetic Resonance Imaging (MRI) scan before the start of treatment. This will be in addition to the PET
(Positron Emission Tomography) scan routinely performed in patients being treated for lymphoma). The
scans will be performed on the same day and we will endeavour to perform one scan immediately
following the other to minimise any inconvenience or loss of time to participants. Patients will then
undergo chemotherapy followed by a second MRI scan 4 weeks after completion of chemotherapy.
Again, this is in addition to the PET scan that is routinely performed at that time.
All participants will be reviewed in outpatients at 6 months, following the completion of their 1 st line
treatment, as per routine.
What is involved in the scan?
MRI scan - MRI uses a strong magnetic field to obtain high quality images of the body in 3 dimensions. Itdoes not require any injection. However, it is noisy and requires you to lie still whilst having the scanperformed. People who suffer from claustrophobia may feel uncomfortable having an MRI scanperformed. Please let us know if you suffer from claustrophobia.
A newer technique called diffusion-weighted MRI imaging (DWI) has been developed to gain extrainformation about your cancer and how it is responding to treatment (this technique gives additionalinformation particularly about how active the cancer is in terms of how many living cells there are in each

tumour). Participants will be scanned from the top of the head to the thighs, as in a PET scan, and thisstudy will take approximately 20 minutes.
What are the possible benefits of taking part? We think Whole Body-Diffusion Imaging (DWI) could beused for pre-treatment and post-treatment assessment in lymphoma patients with accuracy as good asthat of PET/CT scanning. If this is the case then the current practice of performing PET/CT scans, which
involves radiation exposure, could potentially be replaced by Whole Body-DWI, as the latter has theadvantage of being free from radiation exposure and is also quicker to perform.
What are the benefits of taking part? There is no immediate direct benefit to participants, although theinformation we get from this study may help us to improve the future diagnosis, staging and monitoringtreatment response in patients with lymphoma.
Are there any side affects? No side effects of any kind are anticipated from the extra MRI study asthere is no radiation involved in this test.
Taking part in this study will be kept confidential. All information that is collected about you during the
course of this study will be kept strictly confidential. With your permission a letter will be sent to your
GP informing him/her of your participation in this study.
What will happen to the results of the research study? This may be presented in regional, national or international meetings and maybe submitted for publication in medical journals. However, no volunteer will be individually identified and participation in this study in no way affects future treatment.
