The
study was to evaluate the efficacy of hepatocyte-phase imaging in
characterization of focal hepatic lesions among cirrhotic liver using
gadoxetic acid enhanced MRI. Our results revealed SNRs/CNRs of HCC were
significantly decreased in hepatocyte phase (P<0.05) and the benign DN
showed no significant difference (P>0.05). Severe additional HCC were
diagnosed by hepatocyte-phase imaging. The diagnostic performance is
significantly higher in the imaging set with hepatocyte-phase imaging
(P=0.016). In conclusion, combination of gadoxetic acid-enhanced dynamic
study and hepatocyte-phase imaging could provide better diagnostic
performance than dynamic study only in characterization of focal liver lesion
among cirrhotic liver.
