FIG 3.
Validation results. (A) Overlay of the tissue region boundaries (black) and the corresponding magnetic resonance imaging (MRI) segmentations (red) for tumor and kidney regions. Dice similarity coefficients (DSCs) are calculated for tumor and kidney tissues separately. (B) Left: Overlay of a photograph of the section from the first patient and the corresponding MRI maps, including anatomic region segmentations (top) and multiparametric tumor habitats (bottom). Right: Relative distributions of imaging parameters for the 3 tumor habitats. AU, arbitrary units; DCE, dynamic contrast-enhanced; IVIM, intravoxel incoherent motion; RP, renal pelvis; T1w, T1-weighted; T2w, T2-weighted.
