Reporting expectations for BI-RADS category 5 classifications are feasible, achievable

When using the American College of Radiology’s Breast Imaging-Reporting and Data System (BI-RADS) to classify a breast lesion, radiologists are expected to only use the category 5 assessment when the likelihood of malignancy, or positive predictive value (PPV), is at least 95 percent. Is that a feasible expectation?
