INTRODUCTION

ULTRASOUND o Cheaper widely available o fine-needle aspiration (FNA) and biopsy

CT o Radio- dense calculi

MRI o Superficial deep parts and the facial nerve o To evaluate minor salivary gland diseaseo Perineural spread or skull base involvement of tumor o Deep spaces involvement for surgical assessment o Thin slices (3D FIESTA) ndash ducts can be studied

AIM

To assess the usefulness of MRI in the diagnosis of salivary gland pathologies

REVIEW OF LITERATUREMR Imaging of Parotid Tumors Typical Lesion

Characteristics in MR Imaging Improve Discrimination between Benign and Malignant Disease

84 pts with parotid gland tumors were studiedHistology was available for all tumors MR imaging parameters analyzed were

o signal intensity o contrast enhancemento lesion margins (well-defined versus ill-defined) o lesion location (deepsuperficial lobe) o growth pattern (focal multifocal or diffuse) ando extension into neighbouring structures o perineural spread o Lymphadenopathy

Christe C Waldherr R Hallett P Zbaeren H Thoeny

AJNR Am J Neuroradiol 321202ndash07 1113093 Aug 2011

Low signal intensity on T2-weighted images and postcontrast ill-defined margins of a parotid tumor are highly suggestive of malignancy

MATERIALS AND METHODS o Prospective study May 2013- Oct 2014 o 24 Patients with suspected salivary gland disease o 5 Excluded as follow up was not availableo MRI findings correlated with clinical follow up (10) and

surgical histopathological diagnosis(9) in 19 pts

TECHNIQUE

o Procedure ndash Head first Head neck coil

Scan covers salivary gland and neck region

CORRELATION

Christie et al found 70 accuracy in diagnosing benign parotid lesions and 36 in malignant lesions

Our study showed an accuracy of 95 in diagnosing salivary gland pathologies

CONCLUSION

There are certain MRI characteristics for each of the common salivary gland pathologies which helps in the exact diagnosis

MRI showed an accuracy of 95 in diagnosis of salivary gland pathologies

Hence MRI is an extremely useful in the diagnosis of salivary gland pathologies
