Purpose: To retrospectively analyze the positive predictive values (PPVs) of the breast lesions classified as categories 4 and 5 by using Breast Imaging reporting and Date System (BI-RADS) ultrasonography (US).
Materials and Methods: Between May 2012 and December 2012, the 1166 breast lesions of 1061 patients were reported BI-RADS US category 4 and 5. We reviewed the frequency, pathologic or clinical course.
The positive predictive value (PPV)s for category 4a, 4b, 4c and 5 were evaluated.
Results: Among the 1166 lesions, the 834 lesions were pathologically confirmed as benign lesions and the 292 lesions were pathologically confirmed as malignant lesions. The 40 lesions were not pathologically confirmed.
The PPV for category 4 was 13.6% and the PPVs for subcategory 4a, 4b and 4c 5 were 6.6%, 40.8% and 80%. And the PPV for category 5 was 98%.
Conclusion: In our hospital, the PPVs for BI-RADS US category 4a, 4b, 4c and 5 were presented to show the range of BI-RADS US, so it was appropriately subcategorized.
