  1. Pre-G-CA = measurement before the intravenously administered contrast agent; Post-G-CA = measurement after the intravenously administered contrast agent; CNR = Contrast-to-Noise Ratio; ADC = Apparent Diffusion Coefficient. P value indicates the statistical difference between the CNRs in pre- and post-contrast images.
