Dynamic slice-dependent update of linear shim gradients and center frequency was implemented in 3 T breast imaging. The method was applied to axial bilateral breast DWI on four volunteers. In all volunteers the measured B0 maps showed significantly improved homogeneity. Anatomy-referenced ADC maps also showed reduced image registration error obtainable with the proposed method.
