A workflow is demonstrated for B₁ mapping using a multi flip-angle fitting technique in conjunction with a single-shot EPI read-out. Resulting field maps are shown to differ minimally when compared to the same measurements made with a low EPI factor. With the protocol presented here, all necessary measurements for whole-brain mapping are acquired in less than 2 minutes.
