Objective To investigate the value of CT scan and enhanced scan in the judgment of hepatitis grading of patients with chronic viral hepatitis. Methods 107 patients with chronic viral hepatitis treated in our hospital from December 2013 to October 2015 were selected as the research objects and all were given CT plain scan and enhanced scan. The hepatitis grading of all subjects was recorded and the differences in CT signs of patients with different hepatitis grading were observed. Results The CT scanning images of patients with chronic viral hepatitisshowed that the gallbladder wall was thickened and there were edemain fossa for gallbladder, tenlargement of lymph nodes, ascites, splenic enlargement and halo signs around intrahepatic vessels, etc. The proportion of patients with severe chronic viral hepatitis having above mentioned abnormal signs was significantly higher than those of mild and moderate patients(P<0.05). Conclusion There are some differences in CT scanning signs between patients withchronic viral hepatitis of different hepatitis grading. Most patients with severe chronic hepatitis are complicated withedemain fossa for gallbladder,ascites,halo signs around intrahepatic vessels and other CT signs. Doctors can take this as asupplementary method of evaluating the severity of patients' disease to save the time of diagnosis and treatment.
