Imaging Directed Needle Core Biopsies with “Atypical” Diagnoses

Breast needle core biopsies performed in 2010 at the Woman’s Imaging Center were reviewed. The “atypia” diagnostic category showed a rate increase over previous years. Correlation with subsequent excisional biopsy diagnoses showed a 7% malignancy rate, which is lower than that observed previously in our department and in recent published studies.
