Purpose
To compare the effectiveness of prospective, retrospective, and combined (prospective + retrospective) EPI distortion correction methods in bilateral breast diffusion‐weighted imaging (DWI) scans.
Methods
Five healthy female subjects underwent an axial bilateral breast DWI exam with and without prospective B0 inhomogeneity correction using slice‐by‐slice linear shimming. In each case, an...
PurposeTo demonstrate dynamic slice‐dependent shim update as a simple method to reduce susceptibility‐induced B0 inhomogeneity and associated pixel shift artifacts in diffusion‐weighted echo planar imaging (DW‐EPI) in 3 T breast imaging.
MethodsDynamic slice‐dependent update of linear shim and center frequency was implemented in a dual‐echo B0 mapping sequence and a DW‐EPI sequence. Multi‐slice axial...
