We present initial results of our attempt to determine whether a tight temporal footprint (15 s) and spatial resolution (1 mm isotropic) can better characterize heterogeneously enhancing lesions in the breast. Eight volunteers underwent a standard clinical DCE and a rapid 3D radial (VIPR) SPGR DCE over two days of scanning. The 3D-VIPR SPGR method was able to provide good visualization of a lesion in three orthogonal reformats displaying heterogeneous enhancement as well as good depiction of the margin enhancement. To date this method has only been used on unilateral exams but should be expandable to bilateral imaging.
