ABSTRACT
Objective To investigate mut-slice spiral CT(MSCT) and MRI features and correlated pathological basis of stasis cirrhosis.Methods MSCT and MRI findings of 35 patients with stasis cirrhosis (study group) and 35 patients with posthepatitic cirrhosis (control group) were studied retrospectively. Volume index of liver and spleen, caliber of hepatic vein and the number of regenerative nodules exceeded 5mm in diameter were measured.The contrast-enhanced patterns of liver parenchyma, contrast medium reflux, ascites, the number of varices and correlated abnormalities were reviewed.Results The volume indexes of liver and spleen, calibers of hepatic vein were (4434.95±1283.08) cm~3,(621.92±400.33) cm~3 and (3.61±0.81) cm in the study group,(2569.73±853.06) cm~3,(1275.61±727.51) cm~3 and (1.92±0.46) cm in the control group,respectively.The number of the patients showed waves of borderline, inhomogeneous pattern of parenchymal contrast enhancement, regenerative nodules exceeded 5mm in diameter, contrast medium reflux, varices and ascites were 5, 29, 17, 20, 16 and 6 cases in the study group,29,0,5,0,35 and 26 cases in the control group,respectively,there were statistic differences between the study group and control group(P＜0.05).Conclusion MSCT and MRI play a invaluable role in the diagnosis and differential diagnosis and etiological diagnosis of stasis cirrhosis.
ABSTRACT
Objective To investigate the imaging features of Budd-Chiari syndrome(BCS) on 64 slice spiral computed tomography(64SCT) and the diagnostic value of 64SCT for BCS.Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography(DSA).Two abdominal radiologists analyzed the CT imaging features of BCS,paying attention to the vascular lesion,the morphology abnormality of the liver and the degree of portal hypertension,with review of DSA findings.Results ①The accuracy of 64SCT for BCS was 93.1%(27/29),and there were 2 false positive cases and no false negative case.The accuracy of 64SCT for those patients with thrombosis of inferior vena cava(IVC) and(or) hepatic vein(HV) was high as compared to those with stenosis of IVC and(or) HV.②The morphology abnormality of the liver included hepatomegaly(24 cases),low attenuation(27 cases) and inhomogeneous pattern of parenchymal contrast enhancement(5 patients in arterial phase and 19 patients in portal vein phase).③The images of all the patients showed the features of portal hypertension.Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom.The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients.For those patients with stenosis of IVC and(or) HV,however,the diagnostic power of 64SCT is limited.

ABSTRACT
Objective To investigate multi-slice spiral CT (MSCT) and MRI features of stasis cirrhosis and the diagnostic value of MSCT and MRI. Methods MSCT and MRI findings of 35 patients with stasis cirrhosis were studied. The size of liver and spleen, the diameter of hepatic vein (HV), enhancement pattern of liver parenchyma, contrast medium reflux in inferior vena cava (IVC) and (or) HV, ascites, number of varices and correlated abnormalities were reviewed. Results The volume index of liver and spleen of 35 patients was 4 434.95 cm3 and 621.92 cm3 respectively. The mean diameter of HV of 27 patients (77.1%) was 3.61 cm and HV of other 8 patients (22.9%) were too small to show. Number of patients showed waves of borderline, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, varices and ascites was 5 (14.3%), 29 (82.9%), 20 (57.1%), 16 (45.7%), and 6 (17.1%), respectively. Correlated abnormalities included cardiac enlargement 4 cases (11.4%), pericardium thickening 11 cases (31.4%), and pericardial effusion 2 cases (5.7%). Conclusions Stasis cirrhosis mainly demonstrate liver enlargement, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, and slight portal hypertension. MSCT and MRI play invaluable roles in diagnosis, differential diagnosis and etiological diagnosis of stasis cirrhosis.
