The clinical use of multiparametric MR imaging at 7T is
feasible with good or excellent image quality.
Multiparametric MR imaging of the breast with DCE MR
imaging and DWI at 7T seems to have the potential to
diagnose breast cancer with high diagnostic accuracy
(AUC 0.941). Multiparametric MR imaging of the breast
with DCE MR imaging and DWI at 7T improves specificity
as compared to interpretation of DCE MRI alone
(p=0.031). Multiparametric MR imaging of the breast with
DCE MR imaging and DWI at 7T can avoid unnecessary
breast biopsies recommended with DCE MR imaging, in our
series in 6/8 (75%, p=0.031) of benign breast tumors.
