Core Tip
Core tip: In order to optimize the hepatobiliary phase delay time (HBP-DT) of Gd-EOB-DTPA-enhanced magnetic resonance imaging for more efficient identification of hepatocellular carcinoma (HCC) in cirrhosis of different degrees of severity, we analyzed the signal intensity and ratios between liver parenchyma and HCC, and the percentages of HCC visibility at a series of HBP-DT points in those patients. The severity of cirrhosis was shown to negatively influence HCC visibility, but DT-10 is already enough and more efficient than longer DT to identify HCC in Child-Pugh (CP)-A and CP-B cirrhosis. DT-15 or longer DT seems more appropriate for HCC visibility in patients with CP-C cirrhosis.
