中文摘要：
目的探讨磁共振肝脏动态增强与肝门静脉三维成像一站式检查代替单纯三维对比增强腹部血管成像检查评估肝门静脉的可能性和可靠性，为“一站式检查”的序列设计提供参考依据。方法选择100例病历资料完整、临床确诊肝硬化的住院患者，其中50例行应用THRIVE—BH序列的磁共振肝脏动态增强与肝门静脉三维成像一站式检查，为A组；另外50例行应用CE—MRA—ABD序列的单纯的三维对比增强腹部血管成像检查，为B组。对两组肝门静脉图像分别进行单盲分析并评分，结果使用SPSS13．0软件进行统计分析。结果肝门静脉的肝外部分：A组肠系膜下静脉干显示率低于B组（P〈0．05）；肝门静脉的肝内部分：A、B组间无统计学差异（P〈0．05）。结论应用THRIVE—BH序列的磁共振肝脏动态增强与肝门静脉三维成像～站式检查替代应用CE—MRA—ABD序列的单纯的三维对比增强腹部血管成像检查评估肝门静脉是可行的，可作为肝硬化患者随访的重要手段。
英文摘要：
Objective To compare one-stop dynamic contrast-enhanced MRI and 3D MRI of portal vein with 3D contrast- enhanced abdominal MR angiography （MRA）. Methods One hundred in-patients with clinical diagnosis of cirrhosis were divided randomly into two groups of 50 patients. One group underwent one-stop MRI including dynamic contrast-enhanced MRI and 3D MRI of the portal vein using the THRIVE_BH sequence. The other group underwent 3D contrast-enhanced abdominal MRA. The image quality of the portal vein using the two methods was compared. Results The inferior mesenteric venous branch of the extra-hepatic portal vein was less well seen on dynamic contrast-enhanced and 3D THRIVE_BH MRI than 3D contrast-enhanced MRA （P 〈 0.05）. Visibility of the intra-hepatie portal vein was not significantly different between the two methods （P 〈 0.05）. Conclusions One-stop examination including dynamic contrast-enhanced and 3D THRIVE_BH MRI of portal vein can be useful for monitoring cirrhosis.
