The purpose of this study was to compare bilateral
breast-DWI with sub-mm-resolution (0.9mm2) at 7T with 3T
(1.4mm2) in the same patients. The results suggest that
breast 7T DWI can be performed with significantly higher
spatial resolution than at 3T, with comparable SNR.
Therefore, 7T DWI in breast cancer has the potential to
improve lesion detection and/or differentiation. In
addition, the high resolution of 7T DWI at b=0s/mm2 has
very similar contrast as STIR and could, therefore,
potentially replace additional T2-weighted MRI and save
measurement time.
