中文摘要：

目的：探讨磁共振肝动态增强与肝门静脉成像一站式检查的应用价值。方法：200例住院患者的磁共振影像资料，其中150例（实验组）行磁共振肝动态增强与肝门静脉成像一站式检查，另50例（对照组）分别行肝脏磁共振动态增强检查、磁共振对比增强肝门静脉成像检查。比较两组间肝门静脉图像质量和磁共振平均侯检时间、检查总时间、总费用有无差别，观察对照两组中肝癌、门脉癌栓、肝门静脉高压症侧支静脉曲张的影像诊断与手术病理结果或其他辅助检查结果是否相符。结果：与对照组比较，实验组磁共振平均侯检时间缩短66．67％（P〈0．01），检查总时间平均减少43．84％（P〈O．01），总费用降低34．58％。对肠系膜下静脉和肝门静脉肝内分支的检测能力对照组均优于实验组（P〈O．05）。两组中肝癌、门脉癌栓、肝门静脉高压症侧支静脉曲张的影像诊断与手术病理结果或其他辅助检查结果相符。结论：磁共振肝动态增强与肝门静脉成像一站式检查能同时获得肝实质动态增强信息和肝门静脉解剖信息，有助于制定治疗方案和指导手术、介入进行，并降低了患者的经济负担和时间成本。

英文摘要：

Objective： Discuss clinical value of magnetic resonance imaging （MRI） of liver dynamic contrast-enhancement and hepatic portal venography in one station examination, Methods： MRI data of 200 hospitalized patients were collected. One hundred and fifty of them undertake one station examination as the experimental group, while the other 50 patients undertake both contrast-enhanced portal vein angiography and liver dynamic contrast-enhancement as the control group. Compare the image quality of the hepatic portal vein, the average waiting time, the total time for MRI, and the total cost. Check the MRI imaging diagnosis of liver cancer, portal vein tumor thrombus, varicose veins in portal hypertension syndrome with surgical and pathological findings and other auxiliary examination results. Results： Compared with the control group, the average waiting time of the experimental group was shortened by 66.67%（P〈0.01）, the total time for MRI was shortened by 43.84%（P〈0.01）, and the total cost was lowered by 34.58%. The detection capabilities of the control group were better than those of the ex- perimental group in both inferior mesenteric vein and intra-hepatie branches of hepatic portal vein（P〈0.05）. There was no sta- tistical difference about the match rate of MRI diagnosis and surgical finding or other auxiliary examination results between experimental group and control group. Conclusion： MRI of liver dynamic contrast-enhancement and hepatic portal vein in one station exatnination can get the information about liver parenchyma and hepatic portal venous anatomy. It can also lowered the economic burden and time cost.
