Figure 3. A 71-year-old female with endometrial carcinoma. ROI was placed in endometrial carcinoma area and superficial myometrial area. Both A-C and E-G are the Ktrans, Kep and iAUC, respectively, D and H were DCE concentration curves of the mass and superficial myometrial layer. The calculated Ktrans, Kep and and Ve values of the mass were:0.085 min−1, 0.646 min−1, 0.131, respectively. The Ktrans, Kep and and Ve values of the superficial myometrial layer were:0.31 min−1, 0.981 min−1, 0.316, respectively.

Figure 1. The Kep distribution of benign and malignant endometrium lesions. The mean Kep values of these two group of statistical measurements are: benign: 0.627 ± 0.673min−1and malignant: 1.412 ± 1.143 min−1 (T test, p<0.01). The area under the ROC curve of Kep value is 0.82 which indicates that the Kep values have very good predictive ability for differentiation between benign and malignant endometrium lesions
