摘　　要：目的 研究分析CT血管造影（CTA）与磁共振血管成像（MRA）对门静脉高压的检出敏感性,探讨二者对门静脉高压的诊断价值。方法 收集本院经手术探查或血管介入造影诊断确诊为门静脉高压血管病变患者的临床和影像学资料，回顾性分析CTA和MRA对门静脉高压诊断准确性，对比二者对门静脉高压诊断的敏感性。结果 共351例门静脉高压患者纳入本研究，其中肝前型门静脉高压89例，肝内型门静脉高压121例，肝后型门静脉高压131例。CTA检出门静脉高压分别为79例、120例、128例，MRA分别为85例、101例、97例。 CTA对门静脉高压检出率为93.16%，与手术探查和血管介入造影检出情况统计学差异明显（P^1,3〈0.000 1〈0.05），MRA对门静脉高压检出率为80.63%，与手术探查和血管介入造影检出率的差异有统计学意义（P^1,2〈0.000 1〈0.05），且与CTA检出率的差异也有统计学意义（P^2,3〈0.000 1〈0.05）。结论 就检出率和敏感性而言，CTA的敏感性远高于MRA,且是无创性检查，值得临床推广。Objective To investigate the sensitivity difference between CT angiography （CTA） and MR angiography （MRA） in detecting portal hypertension,and explore the diagnostic value of the two methods for portal hypertension. Methods The imaging data of portal hypertension patients who were diagnosed by surgical exploration or vascular intervention in our hospital were collected, the accuracy and sensitivity of CTA and MRA in portal hypertension diagnosis were analyzed. Results A total of 351 portal hypertension patients were included in our study,prehepatic portal hypertension were 89 cases, intrahepatic portal hypertension were 121 cases, posterior portal hypertension were 131 cases. The detective cases about prehepatic portal hypertension, intrahepatic portal hypertension and posterior portal hypertension in MRA group were 85 cases,101 cases and 97 cases,in CTA were 79 cases, 120 cases and 128 cases. The portal hypertension detection rate of CTA was 93.16%, there was significant difference with surgical exploration or interventional angiography （P^1,3 〈0.000 1〈0.05）.The portal hypertension detection rate of MRA was 80.63 % ,there was significant difference with surgical exploration or interventional angiography （ P^ 1,2 〈0.000 1 〈0.05 ）, the differences between MRA and CTA was significant （ P ^2.3 〈 0. 000 1 〈 0.05 ）. Conclusion The sensitivity of CTA is much higher than MRA,which is a non-invasive examination,and worthy of clinical promotion.
