Comparison of Dynamic and Liver-Specific Gadoxetic Acid Contrast-Enhanced MRI versus Apparent Diffusion Coefficients
Figure 5
ROC curves generated from contrast ratio (CR) and enhancement ratio (ER) parameters.
These were used for identification of hepatocellular carcinoma (HCC), focal nodular hyperplasia (FNH), hemangiomas, and adenomas in the pre-contrast, arterial, portal venous (PV), and venous phases. * reflects statistically significant (p<0.05) differences relative to a random test (AUC = 0.5). Parameters leading to the highest absolute AUC values are boxed; these parameters were utilized for comparisons with hepatobiliary phase imaging.
