Introduction:. The present study was conducted with an aim to assess the role of MRI for evaluation of adnexal masses and to find out the diagnostic accuracy of MRI in the diagnosis of adnexal masses against the gold standard test ‘histopathology’. Materials and Methods: This is a prospective comparative study conducted in the Department of Radio Diagnosis, Index medical college hospital and research centre.50 women were taken in our study. These patients were first referred for ultrasonography with history of adnexal masses from gynaecological department. The magnetic resonance imaging was done using 1.5 Tesla MRI machine with patient in supine position.Then the lesion sample was taken and sent for histopathological examination. The results obtained on the MRI were evaluated against the histopathology results and the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of MRI was calculated.
