Abstract: Magnetic Resonance Imaging has higher sensitivity and specificity for detecting, localization and characterization of intracranial brain tumours. Of all the brain tumours, 80 % are supratentorial, of which 40 % are extra-axial. The objective of our study is to assess diagnostic ability of MRI in characterizing various supratentorial extra-axial tumours using T1, T2 weighted images, Diffusion-weighted imaging (DWI), Susceptibility weighted imaging (SWI) and contrast-enhanced image. It is a prospective study conducted in the Department of Radio-diagnosis, Narayana Medical College and Hospital, Nellore, Andhra Pradesh from June 2018 - February 2019 using 3Tesla whole-body MR system. In the present study, the majority of the patients belonged to the age group of 40-50 years, 26 patients were males, and 24 were females. In males majority had a meningioma, in females majority had pituitary adenoma. Meningiomas are the most common brain tumours (44 %), followed by pituitary adenomas (20 %). Headache and vomiting are the most common symptoms.
