Abstract
Eighteen cases of severe atypical epithelial hyperplasia of the breast were detected preoperatively by computed tomography breast scanner (CT/M) with contrast enchancement. The CT number before enhancement ranged from -17 to +31 and increased to 26-42 after enhancement (5.2-8.4% increase in attentuation). CT/M can differentiate these potentially precancerous lesions from benign fibrocystic disease.
