目的：以DSA为诊断金标准，探讨CTA、MRA在老年人后循环缺血(posterior circulation ischemia,PCI)病因中的诊断价值及优缺点。方法回顾性分析经DSA确诊为后循环缺血的35例患者的脑MRA及CTA图像，并计算两种血管成像方法对病因诊断准确性。结果35例患者共113支血管病变，病变分别位于椎动脉(49.6%56/113)、基底动脉(23.0%26/113)、大脑后动脉(27.4%31/113)。MRA、CTA对病变血管的诊断准确率分别为77.0%、86.7%，与DSA对比，MRA对老年后循环缺血病因的Kappa值为0.70；CTA对老年后循环缺血病因的Kappa值为0.82。结论与MRA相比，CTA在诊断后循环血管狭窄和闭塞具有更高的准确性，可作为诊断PCI病因的可靠手段。
目的：以DSA為診斷金標準，探討CTA、MRA在老年人後循環缺血(posterior circulation ischemia,PCI)病因中的診斷價值及優缺點。方法迴顧性分析經DSA確診為後循環缺血的35例患者的腦MRA及CTA圖像，併計算兩種血管成像方法對病因診斷準確性。結果35例患者共113支血管病變，病變分彆位于椎動脈(49.6%56/113)、基底動脈(23.0%26/113)、大腦後動脈(27.4%31/113)。MRA、CTA對病變血管的診斷準確率分彆為77.0%、86.7%，與DSA對比，MRA對老年後循環缺血病因的Kappa值為0.70；CTA對老年後循環缺血病因的Kappa值為0.82。結論與MRA相比，CTA在診斷後循環血管狹窄和閉塞具有更高的準確性，可作為診斷PCI病因的可靠手段。

Objective To study the value of CT angiography(CTA) and magnetic resonance angiography(MRA) in the diagnosis of the etiology of the elderly posterior circulation ischemia, compared with digital subtraction angiography(DSA). Methods A retro spective analysis of 35 patients diagnosed posterior circulation ischemic were checked by MRA and CTA.The locations of the lesions shown by various imaging techniques were analyzed and the diagnostic accuracy was calculated. Results A total of 113 diseased vessel segments were identified by DSA. After consensus interpretation, the lesions were located in the vertebral artery(49.6% 56/113), basilar artery(23.0% 26/113), posterior cerebral artery (27.4% 31/113).The diagnostic accuracy of MRA, CTA was 77.0%, 86.7% respectively. Compared with DSA, the Kappa value was 0.70, 0.82 for the diagnosis of the etiology of the elderly posterior circulation ischemia. Conclusions CTA has a higher accuracy than MRA and is recommended over TOF MRA for detection of posterior circulation ischemia.CTA results had a significant effect on patient clinical management.
