| 摘 要： | 目的探讨门静脉海绵样变(CTPV)的MRI表现及其诊断价值。方法收集16例经手术病理证实的CTPV患者,均做了MRI平扫、动态增强扫描,5例做了门静脉动态对比增强(DCE-MRA)检查。分析其MRI影像表现。结果16例CTPV,MRI上均明确了病因。CTPVMRI平扫表现门静脉主干、分支及属支闭塞,门静脉周围可见丰富的侧枝血管。动态增强动脉期7例见肝脏异常灌注,门静脉期肝门区周围异常丰富侧枝血管。DCE-MRA直观显示上述异常改变。6例伴胆管不规则狭窄。结论CTPV具有特征性的MRI表现,MRI对CTPV诊断及明确病因具有重要价值。

| Abstract: | Objective To investigate MRI manifestions of cavernous transformation of portal vein(CTPV),and to evaluate the MRI value in diagnosing CTPV. Methods 16 patients with CTPV proved by surgico-pathology underwent MR plain scan,dynamic con-trast enhancement and 5 patients were performed with dynamic contrastenhanced magnetic resonance angiography(DCE-MRA).The MRI features of CTPV were reviewed retrospectively. Results The etiology of 16 cases with CTPV was showed in MRI.The obstruction of portal vein and its bra... |
