(a,b) β-TM patient, 25-year-old male, preoperative examination of HSCT. CMRTools in FIG. 1a shows that the average value of H-T2* is 27.17, R2 (goodness of fit) is 0.9942, and 8 echo SI are included. CMRTools in FIG. 1b shows that the average value of L-T2* is 1.90, R2 is 0.999, the SI of the first five echoes are included, and the cross represents the SI of the discarded deviation from the fitted curve. (c,d) β-TM patient, a 14-year-old male, was examined after HSCT. CMRTools in FIG. 1c shows that the average value of H-T2* is 28.00, R2 is 0.9991, and 8 echo SI are included. CMRTools in (d) shows that the average L-T2* is 1.83, R2 is 0.9931, and 12 echo SI are included.
