摘　　要：目的探讨磁共振血管成像与多螺旋CT诊断缺血性脑卒中的价值。方法选2019年5月至2021年5于我院的190例缺血性脑卒中患者,均给予磁共振血管成像(MRA)、多螺旋CT,以数字减影血管造影对比两种方法的诊断准确率和特异度。结果和DSA诊断结果相比,MRA闭塞的诊断准确率为66.7%,轻度狭窄的诊断准确率为96.2%,中度狭窄的诊断准确率为94.6%,重度狭窄的诊断准确率为89.7%。和DSA诊断结果相比,MRA闭塞的诊断准确率为33.3%,轻度狭窄的诊断准确率为76.9%,中度狭窄的诊断准确率为89.2%,重度狭窄的诊断准确率为79.3%。MRA诊断准确率、特异度、灵敏度均比多螺旋CT高,且漏诊率比多螺旋CT低(P<0.05)。结论缺血脑卒中患者诊断中相较于多螺旋CT,MRA应用价值更高,其诊断准确率、特异度、灵敏度均比多螺旋CT高,且漏诊率低,能为临床的确诊和治疗提供依据。Objective To explore the value of magnetic resonance angiography and multi-spiral CT in the diagnosis of ischemic stroke.Methods 190 patients with ischemic stroke in our hospital from May 2019 to May 2021 were selected and received magnetic resonance angiography(MRA)and multi-spiral CT.Digital subtraction angiography was used to compare the accurate diagnosis of the two methods.Rate and specificity.Results Compared with the diagnosis results of DSA,the diagnostic accuracy of MRA occlusion was 66.7%,the diagnostic accuracy of mild stenosis was 96.2%,the diagnostic accuracy of moderate stenosis was 94.6%,and the diagnostic accuracy of severe stenosis was 89.7%.Compared with the diagnosis result of DSA,the diagnostic accuracy of MRA occlusion was 33.3%,the diagnostic accuracy of mild stenosis was 76.9%,the diagnostic accuracy of moderate stenosis was 89.2%,and the diagnostic accuracy of severe stenosis was 79.3%.The diagnostic accuracy,specificity,and sensitivity of MRA were higher than that of multi-spiral CT,and the missed diagnosis rate was lower than that of multi-spiral CT(P<0.05).Conclusion Compared with multi-spiral CT in the diagnosis of ischemic stroke patients,MRA has higher application value.Its diagnostic accuracy,specificity,and sensitivity are higher than that of multi-spiral CT,and its missed diagnosis rate is low,which can provide clinical diagnosis and treatment in accordance with.
