Breast calcification imaging.

Breast calcifications are a common mammographic finding, present on 86% of images. Although usually benign, they also can be malignant. Characteristics such as their size, shape, number, distribution pattern, location, density, and other findings help determine their pathology. The American College of Radiology's BI-RADS assessment categories and Appropriateness Criteria guidelines help radiologists and other physicians determine appropriate action when calcifications are discovered. This article reviews breast anatomy, the classification of calcifications, malignant vs benign characteristics, imaging techniques for calcifications, and biopsy procedures.
