目的探讨MRI在诊断门静脉海绵样变性(CTPV)中的价值.方法回顾性分析30例经临床证实的CTPV患者的MRI平扫、动态增强扫描和(或)动态对比增强磁共振血管成像(DCE-MRA)资料.结果 30例CTPV患者MRI表现:平扫时可见门静脉主干和(或)分支闭塞,闭塞的门静脉周围可见由侧支循环静脉形成的团块状软组织信号影.动态增强扫描动脉期可见肝实质灌注异常,门静脉期可见广泛开放的侧支循环静脉强化.DCE-MRA显示上述改变更直观.结论 MRI以及DCE-MRA能清晰地显示CTPV及其迂曲扩张的侧支循环.正确认识、直观地评价CTPV侧支循环的影像解剖学特征,为临床采取正确的治疗措施提供更多的依据.

Objective To investigate the value of MRI in the diagnosis of cavernous transformation of the portal vein (CTPV).Methods Plain MRI,dynamic enhanced and (or) dynamic contrast enhanced magnetic resonance angiography (DCE-MRA) findings in 30 patients of clinical-proved CTPV were retrospectively analyzed.Results Among 30 CTPV patients on plain MRI,obliteration of main and (or) branched portal vein were found,and mass-like or reticular abnormal soft-tissue signals were around the vein,which were produced by collateral vessels.On dynamic enhanced MRI,abnormal hepatic perfusion during arterial phase and abnormal enhanced collateral veins during portal phase could be seen.The above signs became more obvious on DCE-MRA.Conclusions MRI and DCE-MRA can clearly visualize the anatomical features of CTPV.It is important and can provide the reliable evidence for planning properly therapeutic protocol to recognize and directly evaluate the CTPV.
