ROIs placement on image with maximum TE (99.9 ms, 1.5 T) of the T2 mapping sequence A from a 39-year-old healthy subject. B was the image with ROIs showed based on image A, and C was the partial enlargement of Fig. 2(B). On image (B), ROIs with label 1 to label 5 represented endometrium (area = 41mm²), junctional zone (area = 102mm²), external-myometrium (area = 201mm²), gluteus maximus (area = 500mm²) and subcutaneous fat (area = 500mm²) from inside to outside respectively, and their T2 values can be obtained from T2 map (D) directly. I and (F) were the image with maximum TE and the corresponding T2 map respectively from a 57-year-old endometrial carcinoma patient, and the ROI was placed carefully on the maximum cross-section of the lesion
