While the Dynamic Contrast Enhanced (DCE) acquisition remains the centerpiece of breast MRI, both signal intensity and the depiction of lesion morphology in T2-weighted images can help to distinguish malignant versus benign lesions. With TRs on the order of seconds, T2-weighted acquisitions are generally inefficient and most often acquired with high in-plane resolution but low through plane resolution. A radial bSSFP acquisition termed 3DPR-SSFP has been shown to provide improved depiction of lesion morphology in comparison to conventional T2-weighed acquisitions. We evaluate the performance of two methods for improving fat suppression of 3DPR-SSFP while retaining the advantage of clear depiction of fine morphological details in the breast.
