MR imaging allows detection of mammographically and clinically occult foci of carcinoma in patients with suspected breast cancer.

MR imaging-guided needle localizations may be performed in a clinical setting with the systems described. Accurate localization of mammographically and clinically occult lesions will allow MR imaging to achieve a clinically significant role.

Fibroadenomas demonstrate marked histopathologic variability. The resultant variability in the MR appearance limits the ability to distinguish between benign and malignant masses on the basis of signal intensity and enhancement alone. Lobulation and internal septation, which appear to reflect intrinsic growth patterns of fibroadenomas, may provide a more reliable basis for distinction.
