CT血管成像和磁共振血管成像对脑动脉狭窄诊断价值的对比分析

Comparative analysis of CT angiography and MR angiography in the diagnosis of cerebral artery stenosis

目的分析CT血管成像、磁共振血管成像分别用于脑动脉狭窄的诊断价值。方法选取2018年6月至2019年6月期间在我院治疗的70例脑动脉狭窄患者作为研究对象,患者均行CT血管成像、磁共振血管成像检查,以数字减影血管造影(DSA)为金标准,比较两组的诊断准确率。结果以DSA检查结果为金标准,CT血管成像的诊断符合率为79%,磁共振血管成像为90%,比较差异有统计学意义(P<0.05)。结论在脑动脉狭窄的诊断中,磁共振血管成像的诊断符合率明显CT血管成像,但二者均有利弊,临床应根据患者的具体情况选择适合的诊断方式。

Objective To analyze the value of CT angiography and MR angiography in the diagnosis of cerebral artery stenosis.Methods Seventy patients with cerebral artery stenosis who were treated in our hospital from June 2018 to June 2019 were selected as the research objects.All patients were examined by CT angiography and MR angiography.The diagnostic accuracy of the two groups was compared with the gold standard of digital subtraction angiography(DSA).Results With DSA as the gold standard,the diagnostic accuracy of CT angiography was 79%,and that of MR angiography was 90%.The difference was statistically significant(P<0.05).Conclusion In the diagnosis of cerebral artery stenosis,the coincidence rate of MR angiography is obvious,but both of them have advantages and disadvantages,clinical diagnosis should be based on the specific situation of patients.
