High spectral and spatial resolution (HiSS) MR imaging provides excellent diagnostic images of breast cancer even without the use of contrast agent. We report on a fast implementation of HiSS MRI using parallel imaging at 3T to achieve clinically feasible imaging times in < 2 mm 3 voxels, with full bilateral coverage. Non-contrast HiSS MRI can be used to obtain images of lesions without artifacts resulting from contrast administration. In addition, spectral information obtained with HiSS MRI can be used to improve detection of small amounts of glandular tissue and improve breast density measurements in risk assessment studies.
