Figure 5:

Scatterplot of T1 and T2 relaxation times for all renal masses. Although both the indolent (low-grade and benign) and aggressive (high-grade and unclassified) groups were distributed across a wide range of T1 and T2 values, the two relaxation times derived from kidney MR fingerprinting provide complementary information in better separation of the two tumor groups, with an area under the receiver operating characteristic curve of 0.89.
