Synopsis

DWI provides beneficial information that has high diagnostic potential of breast lesions. DWIBS can suppresses the background signals including fat tissues effectively, but there are often insufficient fat suppression cases because of non-adaptation TInull were used. In this study we demonstrated that the actual TI for nulling breast fat in DWI is patient-specific and dynamic TI scout scan (DynTI) is useful to explore patient-adaptive TI that can provide more beneficial to increase the robustness of breast DWIBS.
