Current breast MRI protocols are heavily reliant on dynamic contrast-enhanced MRI (DCEMRI), but this practice is not ideal, due to recently reported findings of long-term gadolinium deposition in several tissues. We demonstrate feasibility of EPT analysis as applied to HiSS MRI data, which could simplify the process of lesion delineation relative to the current method and may thus improve the diagnostic accuracy of non-contrast breast MRI. Linearly extrapolated phase, to TE = 0 ms, from complex multi-TE gradient echo images obtained using HiSS MRI was used for this purpose.
