CTA、MRA与DSA诊断在脑血管狭窄疾病诊断中的应用

Application of CTA,MRA and DSA in the Diagnosis of Cerebrovascular Stenosis

目的探究CTA、MRA与DSA在脑血管狭窄疾病诊断中的应用价值。方法随机选取2016年1月—2018年3月在洛阳市东方医院治疗脑血管狭窄疾病的患者共80例,分别给予所有患者行CTA、MRA检查,行CTA检查80例患者中有30例同时行DSA检查;行MRA检查80例患者中有30例同时行DSA检查,时间隔为6天。对比分析检查结果。结果 80例血管狭窄患者行CTA检查检出血管为186条,狭窄血管为26处;行MRA检查检出血管为150条,狭窄血管为20处;30例血管狭窄患者行MRA与DSA诊断MRA检查脑血管狭窄疾病正确率为86.96%;敏感性为85.00%;特异性为92.02%;30例血管狭窄患者行CTA与DSA诊断正确率为96.67%;敏感性为92.31%;特异性为93.00%。MRA与CTA敏感性差异有统计学意义,CTA对脑血管狭窄疾病诊断敏感性高于MRA。结论 CTA、MRA诊断诊断符合率、正确率、敏感性、特异性较高,可作为首选诊断方法,对于误诊和漏诊病例可采用DSA诊断。CTA、MRA与DSA诊断起到相互补充作用,值得临床广泛推广应用。

Objective To explore the value of CTA,MRA and DSA in the diagnosis of cerebrovascular stenosis. Methods A total of 80 patients with cerebrovascular stenosis in the hospital from January,2016 to March,2018 were randomly selected. All the patients were given CTA and MRA. 30 of the 80 patients were examined with DSA. DSA was performed in 30 of 80 patients with MRA, and the time interval was 6 days. The results were compared and analyzed. Results In 80 patients with vascular stenosis,186 vessels and 26 stenotic vessels were detected by CTA. The accuracy rate of MRA and DSA in the diagnosis of cerebrovascular stenosis was 86.96%,the sensitivity was 85.00%,and the specificity was 92.02%. The diagnostic accuracy rate of CTA and DSA in 30 patients with vascular stenosis was 96.67%. The sensitivity was 92.31%. The specificity was 93.00%. There was statistically significant difference between MRA and CTA. The sensitivity of CTA was better than MRA. Conclusion The diagnostic coincidence rate,correct rate, sensitivity and specificity of CTA and MRA are high,so it can be used as the first choice diagnosis method. CTA,MRA and DSA play a complementary role in diagnosis,which is worthy of extensive clinical application.
