The 3DREAM sequence provides a fast technique for whole-brain B1 mapping, but suffers from different blurring levels in FID and STE* images. We developed a new variant of the 3DREAM sequence with a spiral readout to mitigate this problem. The spiral readout shortens the echo train duration and reduces the number of excitations after the STEAM preparation significantly. This leads to similar blurring levels in FID and STE* images and increases the effective resolution of flip angle maps. As a result, correction strategies for different blurring levels are no longer necessary.
