Pure ductal carcinoma in situ: A range of MRI features

OBJECTIVE. The purpose of this article is to describe and illustrate the variety of common morphologic features, enhancement patterns, and kinetics of pure ductal carcinoma in situ (DCIS) on dynamic contrast-enhanced MRI of the breast, using the American College of Radiology BI-RADS lexicon. CONCLUSION. Breast MRI plays an important role in the detection of DCIS, which most often appears as nonmass clumped enhancement, in a ductal or segmental distribution, with variable enhancement kinetics.
