摘　　要：目的:探讨CT与MR血管造影诊断颅内动脉瘤的临床价值。方法:选取124例某院2018年8月-2021年8月收治的疑似颅内动脉瘤患者作为研究对象,所有入选对象均接受数字减影血管造影(DSA)、CT血管造影、MR血管造影检查,并以DSA检查为金标准,比较CT与MR血管造影阳性检出率、瘤体直径及瘤颈宽度、诊断效能。结果:经DSA检查确诊96例;CT血管造影检出92例,检出率为95.83%(92/96);MR血管造影检出84例,检出率为87.50%(84/96);观察组阳性检出率高于对照组,有统计学差异(χ^(2)=4.364,P=0.037);CT血管造影灵敏度、准确度为93.75%、93.55%,高于MR血管造影的83.33%、83.87%,有统计学差异(P<0.05)。结论:CT与MR血管造影诊断颅内动脉瘤均具有一定临床价值,但CT血管造影诊断灵敏度、准确度更高,可作为早期筛查首选方式。Objective:To investigate the clinical value of CT and MR angiography in the diagnosis of intracranial aneurysms.Methods:A total of 124 patients with suspected intracranial aneurysms admitted to a hospital from August 2018 to August 2021 were selected as the research subjects.All the selected subjects underwent digital subtraction angiography(DSA),CT angiography and MR angiography.Taking DSA as the gold standard,the positive detection rate,tumor diameter and neck width,and diagnostic efficacy of CT and MR angiography were compared.Results:96 cases were diagnosed by DSA;92 cases were detected by CT angiography,with the detection rate of 95.83%(92/96);84 cases were detected by MR angiography,with the detection rate of 87.50%(84/96);The positive detection rate in the observation group was higher than that in the control group,with statistical difference(χ^(2)=4.364,P=0.037).The sensitivity and accuracy of CT angiography were 93.75%and 93.55%,which were higher than those of MR angiography(83.33%,83.87%),with statistical difference(P<0.05).Conclusion:Both CT and MR angiography have certain clinical value in the diagnosis of intracranial aneurysms,but CT angiography has higher diagnostic sensitivity and accuracy,and can be used as the first choice for early screening.
