Ultrasound Demonstration of Mammographically Detected Microcalcifications in Patients with Ductal Carcinoma in situ of the Breast.

Background Breast microcalcifications are difficult to depict by ultrasound (US). However, recent advances in US equipment and the refinement of breast imaging techniques have improved the detection and characterization of small breast lesions. The present study attempts to determine whether US examination is able to demonstrate nonpalpable breast lesions associated with mammographically detected microcalcifications without mass density or distortion, and to evaluate the clinical reliability of US-guided procedures, especially in cases of ductal carcinomain situ (DCIS) of the breast.
