However 90% of non palpable ductal carcinoma in situ (DCIS) was diagnosed on the basis of microcalcifications alone. A high-quality image and magnification view are required for detection and analysis of microcalcifications The ACR BI-RADS classifies calcifications on mammograms into three categories: typical benign, intermediate concern, and higher probability of malignancy, according to the types and distribution of calcifications Ultrasound is sensitive in the detection of microcalcification in breast cancer when they are within a mass lesion, and is a reliable diagnostic sign of carcinoma when present..
