Role of contrast enhanced breast MRI in diagnosis of breast lesions

Objective: The objective of our study was to evaluate how to categorize breast lesions detected at contrast-enhanced breast MRI in accordance with the imaging findings and the indication for MRI. Subjects and methods: This study included 50 patients, their ages ranged from 18- 70 years. MRI examination included conventional sequences and dynamic series. Morphological features and dynamic parameters were recorded with classification of the findings according to BI-RADS. The findings of each modality were correlated with histopathological results. Results: BIRADS 2, 3 were considered as benign lesions and BIRADS 4, 5 were considered as malignant. There were 17 benign lesions (34 %) and 33 malignant lesions (66 %). DCE-MRI proved to have sensitivity of 100 %, specificity of 70.6 %, PPV of 86.8 %, NPV of 100 % and accuracy of 90.0 %. Conclusion: Our study results indicate that DCE-MRI has high sensitivity and moderate specificity in differentiation between benign and malignant breast lesions.
