Breast cancer is the second most common cancer in Indian women. The aim of this study was to compare the diagnostic accuracy of Magnetic Resonance Imaging (MRI) in detecting the malignant nature of the breast masses with that of Mammography. Fifty patients with suspected breast mass lesion (40 palpable and 10 nonpalpable) were included in this study. Both Mammography and MRI (Plain and Contrast enhanced) were performed in every patient. Ultrasonography and galactorgraphy were performed in few patients wherever required. Following this fine needle aspiration of the breast mass was done and the materials were studied Cytopathologically. For nonpalpable lesions sensitivity of mammography and MRI was 65% and 90%, while the specificity was 25% and 50% respectively. For palpable lesions both the methods showed high sensitivity (Mammography 90% and MRI 95%) and MRI demonstrated comparatively higher specificity (Mammography 30% and MRI 50%). In two mammographically negative patients MRI showed positive result. With the complementary use of MRI, it is possible to increase the sensitivity for detection of breast cancer and multicentric disease. In patients in whom the status of a palpable breast mass remains unclear but where strong clinical suspicion exists, MRI may help to reduce the amount of unnecessary biopsies.
