MR images of a 52-yearold woman with endometrioid carcinoma of stage IA. A Axial T2-weighted image demonstrated a mass in the uterine cavity, approximately 5.9 cm × 4.0 cm in size. B DWI (b = 1000 s/ mm2) showed the method of placing ROI within the tumor area. C ADC image showed that the ADCmean, ADCmin and ADCmax value were 0.710 × 10− 3, 0.673 × 10− 3 and 0.914 × 10− 3 mm2/s. D T2-weighted image showed the ROI of tumor segmentation. E The three-dimensional volume of interest
