摘　　要：目的探讨三维增强磁共振血管成像(3D CEMRA)对门腔静脉系统血管性病变的诊断价值。方法收集40例临床疑诊的门腔静脉血管病变患者,先常规平扫后行门腔静脉系统3D CEMRA检查,并对其影像表现进行分析。结果40例患者中,3D CEMRA清晰显示门脉高压所致门静脉、脾静脉增宽并侧支血管开放19例,门脉血栓5例,门静脉海绵样变性形成9例,胰腺癌浸润门脉有2例,布-加综合征5例。结论3D CEMRA作为一种无创性血管造影技术,能直观显示门腔静脉血管及其病理改变,对临床诊断及治疗有重要作用。Objective To evaluate the application value of three-dimensional contrast enhanced magnetic resonance angiography in the diagnosis of the portal vein and eava inferior diseases. Methods Forty patients with clinically suspected the portal-systemic venous diseases underwent MRI and 3D CEMRA, the obtained images were analyzed. Results In the 40 cases, 31） CEMRA showed 19 cases with portal vein and splenic vein dilation and abnormal vessels, 5 cases with portal vein thrombosis, 9 cases with cavernous transformation of portal vein diseases, tumor invasion portal vein was found in 2 cases, budd-chiari syndrome was found in 5 cases. Conclusion It indicates that the anatomical imaging of the portal vein and cava inferior system can be clearly revealed in 3D CEMRA, which is a non-invasion resonance angiography method, and it is very valuable in the clinical diagnosis and treatment.
