This engineering/clinical MRI methods study evaluated ultrafast volumetric DREAM B1+ mapping to refine patient-adaptive RF shimming at 3T. In 20 patients and three volunteers, a multi-slice adaptive RF shimming approach reduced flip-angle deviations and improved B1+ homogeneity compared with central-slice-based…
