Example of selection the region of interest (ROI) for tumor and reference region. (a), (b), and (c) correspond to the image in the precontrast phase, corticomedullary phase (CMP), and nephrographic phase (NP), respectively. The red circle is for the tumor in three phases. The red oval represents the region in the kidney cortical section used as the reference. These ROIs were consistent for the three scan phases.
