Male breast disease: pictorial review with radiologic-pathologic correlation.

The male breast is susceptible to many of the same pathologic processes as the female breast. Many of these conditions have mammographic, ultrasonographic (US), and magnetic resonance imaging findings that allow differentiation between clearly benign conditions and those that require biopsy. Gynecomastia is the most common abnormality of the male breast and has characteristic imaging features that usually allow differentiation from malignancy.

A feasible high spatiotemporal resolution breast DCE-MRI protocol for clinical settings.

Three dimensional bilateral imaging is the standard for most clinical breast dynamic contrast-enhanced (DCE) MRI protocols. Because of high spatial resolution (sRes) requirement, the typical 1-2 min temporal resolution (tRes) afforded by a conventional full-k-space-sampling gradient echo (GRE) sequence precludes meaningful and accurate pharmacokinetic analysis of DCE time-course data. The commercially available, GRE-based, k-space undersampling and data sharing TWIST (time-resolved angiography with stochastic trajectories) sequence was used in this study to perform DCE-MRI exams on thirty one patients (with 36 suspicious breast lesions) before their biopsies.
