Analysis of Gd-EOB-DTPA-Enhanced Magnetic Resonance Imaging Features of Budd-chiari Syndrome Complicated with Hepatocellular Carcinoma
Objective To investigate the Gd-EOB-DTPA magnetic resonance imaging features of hepatocellular carcinoma(HCC)under the background of Budd-Chiari syndrome(BCS).Methods The clinical data of 14 patients with hepatocellular carcinoma with BCS background and 32 patients with hepatocellular carcinoma without BCS background were analyzed retrospectively,including 24 HCC lesions with BCS background and 41 HCC lesions without BCS background.All patients were examined by Gd-EOB-DTPA enhanced MRI.The MRI features(enhancement mode,capsule,cystic degeneration and necrosis,hemorrhage,ascites,etc.)and differences between the two groups were compared.Results The hyperintense of HCC lesions with BCS background was significantly more than that without BCS background in the portal vein phase,and the hyperintense of HCC lesions with BCS background was significantly more than that without BCS background in the delayed phase,and the differences were statistically significant(P＜0.05).There was no significant difference in signal intensity between the two groups in hepatobiliary phase.The proportion of ascites and female patients with BCS background was significantly higher than that of patients without BCS background,and the proportion of intrafocal hemorrhage was lower than that of lesions without BCS background,the difference was statistically significant(P＜0.05).Conclusion Hepatocellular carcinoma with and without BCS background showed different enhancement patterns in portal venous phase and delayed phase,but there was no significant difference in hepatobiliary phase.
