摘　　要：目的:探讨动态增强磁共振门静脉造影(DCE MRP)在门脉高压症诊断中的价值。方法:对门脉高压症组23例和正常对照组15例行DCE MRP检查。观察23例门静脉高压症在DCE MRP上的表现。结果:对照组15例均清楚显示门静脉。门脉高压症表现为门静脉增粗(21例)、脾静脉迂曲扩张(23例);门静脉分支级数减少(18例);门静脉延迟显影(7例);显示侧枝循环静脉(6例);门静脉血栓形成(3例)。结论:DCE MRP是评价门静脉的一项快速无创的技术,可准确显示门静脉高压症门静脉系统的病理改变。Objective： To evaluate the value of dynamic contrast-enhanced MR portography （DCE MRP） in the diagnosis of portal hypertension.Methods： 15 volunteers and 23 portal hypertensive patients were performed with dynamic contrast-enhanced MR portaphy. The appearances of portal hypertension in 23 cases were observed on DCE-MRP. Results： Portal vein were well demonstrated on DCE MRP in all 15 volunteers. DCE MRP findings in patients with portal hypertension were as follows：enlarged portal vein （n= 21）, tortuous and dilated splenic vein （ n = 23）, decreased sub-branching of portal vein （n = 18）, delayed opacification of portal vein （ n = 7 ）, demonstrarice of portosystemic collaterals （ n = 6）, portal thrombosis （ n = 3）. Conclusion ： DCE MRP is a rapid and noninvasive technique for assessment of portal venous system. It can demonstrate the pathologic changes of portal venous system in portal hypertension exactly.
