PET - CT
ONE STOP SHOP FOR CANCER CARE ANATOMETABOLIC DIAGNOSIS
EARLY DETECTION DEFINES THE SEVERITY & EXTENT
SURVEYS ENTIRE BODY IN A SINGLE STUDY

NONONCOLOGICAL APPLICATIONS OF PET - CT
Cardiology:• Assesment of Myocardial viability
Neurology:• Epilepsy• Neurodegenerative disorders• Anxiety & depressive disorders.

Dual Head Gamma Camera (Millennium MG)
● Radiopharmaceuticals are organ specific chemical compounds combined with radionuclides.
● These radiopharmaceuticals, once administered to the patient, localize to specific organs or cellular receptors which allows us to image the extent of a disease-process in the body, based on the cellular function (Physiology), rather than relying on physical changes in the tissue anatomy.
Dual Head Gamma Camera (Millennium MG)
Application
Functional/Physiological imaging of various Organs/Organ systems
BONE SCAN
● Highly sensitive● Surveys entire body in
a single study● Diagnoses the lesion
earlier than radiograph
EARLYDiagnosis of bone secondaries in a cancer patient
BONE SCAN
THYROID SCAN
Provides the Uptake Function of Thyroid Gland
Detectes Nonfunctioning Nodules (30% of Which Could be Cancerous )
Differentiates Hyperthyroidism Causes
Thyroid Scan Graves’ Disease
Curable with Radioiodine Therapy
● Patient Presented with Thyroid Swelling
● Thyroid Scan Shows Nonfuntioning Nodule
● Biopsy Revealed Thyroid Cancer
● Complete Cure for Thyroid Cancer at early stage (Papillary & Follicular Varieties) is Possible with Surgical Removal of Thyroid Gland with
Neck Lymphnode Dissection
Followed By High Dose Radioiodine Therapy
Comprehensive Cancer Care Under One Roof
RENAL SCAN FUNCTIONAL IMAGING OF RENAL SYSTEM GIVES ACCURATE FUNCTIONAL STATUS ( GFR) RULES OUT URINE OUTFLOW OBSTRUCTION
