In this study, we show an iterative algorithm method for T2-mapping based on fast spin echo (FSE) acquisition. When 180 refocusing pulse is inaccurate, T2 estimation will also be inaccurate due to stimulated echoes. Such error is compensated here by calculating effective flip angle of refocusing pulse for every pixel.
