Title: CT and MRI diagnostic value of chronic virus hepatitis
Abstract: Objective To summarize the direct signs and accompanied characteristic of CT and MRI imaging manifestations of chronic virus hepatitis, for the purpose of improving the level of imaging diagnosis and evaluating its value of clinical application. Methods Forty-one imaging datas from 33 cases with chronic virus hepatitis was analyzed retrospectively. CT scans were performed in 21 cases, and MR imaging in 12 cases. The changes of the morphous ,density or signal of liver, bile duct, spleen and portal venous system were observed, and the peak time of liver parenchyma enhancement was measured. Results Of 33 cases, the right liver reduced in size (n=28 cases), the margin of liver irregular (n=15 cases), inhomogeneous (n=18 cases), periportal tracking signs (n=8 cases), spleen swelling (n=23 cases), ascites (n=6 cases), pleural effusion (n=2 cases) and pleural thickening (n=12 cases) were recognized. The peak time of hepatic enhancement in 13 cases were 14.8±8.2 seconds at average. The widespread mottled hyperintensity was found at 2 cases in diffusion-weighted MR imaging. Conclusion CT and MRI had important significance in understanding the condition of patients with chronic virus hepatitis. The characteristic of widespread mottled hyperintensity, periportal tracking signs and delayed peak time of hepatic enhancement were made for definite diagnosis.
