Table 3.

Contrast-to-noise ratio (CNR) means ± standard deviations in images obtained before and after the administration of gadolinium based intravenous contrast agent (G-CA) using fat as the reference value.

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.
