ROC curve of K trans (blue line) and V e (green line) shows comparisons of K trans and V e in ccRCC and non–ccRCCs. With a K trans value of 0.330 min−1, sensitivity and specificity were 76.9% and 71.4%, respectively, and the AUC was 0.819. With a V e of 0.327, sensitivity and specificity were 86.2% and 52.4%, respectively, and the AUC was 0.716.
