摘　　要：目的:探讨门脾静脉血栓的三维动态增强MR血管造影(3DDCE-MRA)的影像特征和诊断价值。方法:27例门脾静脉血栓患者行3DDCE-MRA检查及工作站三维重建,其中肝硬化继发门脾静脉血栓形成19例,非肝硬化继发门脾静脉血栓8例。结果:门脾静脉血栓3DDCE-MRA主要表现为门脾静脉内栓子形成,正常门静脉变形、消失,局部出现扭曲的向肝性侧支血管,肝内可继发动静脉瘘,腹腔及腹壁可见离肝性侧支血管。结论:3DDCE-MRA能清晰显示门脾静脉内栓子,同时完整显示门静脉系统及侧支循环,对临床诊断及治疗门脾静脉血栓具有重要价值。Objective: To investigate the imaging characteristic feature and diagnositic value of three-dimensional dynamic contrast-enhanced MR angiography (3D DCE-MRA) for portal and splenic vein thrombosis (PSVT). Methods: 3D DCE-MRA was performed and the results were processed using 3D reconstruction in 27 patients with PSVT. Nineteen patients were found with liver cirrhosis. Results: The main 3D DCE-MRA appearances of PSVT included embolus of portal and splenic veins, abnormal configuration of portal vein, twisted hepatopetal collateral veins, arterial-portal venous shunts, and hepatofugal collateral blood vessels in abdominal cavity and wall. Conclusion: 3D DCE-MRA can distinctly reveal thrombus in portal and splenic veins and can completely display the portal system and collateral veins, which has great value in the diagnosis and clinical treatment of PSVT.
