Novel FSE Method to Improve T2map Accuracy by Calculating B1map Simultaneously

Yoshihiro Tomoda¹, Hitoshi Ikeda¹

Novel FSE method is proposed to improve the T2map accuracy by calculating B1map simultaneously without scan time elongation. Compared with the legacy CPMG method, T2 estimation error is low enough in a wider range of T2 and refocus FA. In addition, lower refocus FA is applicable to the proposed method, which would decrease SAR and increase the number of max slices per acquisition.
