摘　　要：目的:探讨CT血管成像技术(CTA)在颅内动脉瘤的诊断价值。方法:选取2017年3月-2022年6月通州区人民医院收治的诊断怀疑颅内动脉瘤患者60例为研究对象,行CTA及数字血管造影(DSA),分析CTA在动脉瘤上的诊断效能,比较DSA与CTA的动脉瘤测量数据和图像质量。结果:60例患者经DSA金标准检查出发现动脉瘤(阳性)21例,阴性39例。通过CTA检查出动脉瘤阳性20例,阴性40例,漏诊部位为大脑中动脉1例,漏诊率为4.76%(1/21)。诊断效能分析显示,CTA在动脉瘤诊断上的灵敏度95.24%(20/21)、特异度97.44%(38/39)、准确度96.67%(58/60);CTA和DSA测定动脉瘤口直径、动脉瘤直径比较,差异无统计学意义(P>0.05);CTA与DSA图像质量优良率比较,差异无统计学意义(P>0.05)。结论:CTA对动脉瘤诊断具有较高诊断效能,测量数据及图像质量接近金标准DSA。Objective:To investigate the diagnostic value of CT angiography(CTA)in intracranial aneurysm.Methods:Sixty patients with suspected intracranial aneurysm admitted to Tongzhou District People's Hospital from March 2017 to June 2022 were selected as the research objects.CTA and digital angiography(DSA)were performed to analyze the diagnostic efficacy of CTA in aneurysms.Aneurysm measurement data and image quality were compared between DSA and CTA.Results:Aneurysms were found in 21 patients(positive)and 39 patients(negative)by DSA gold standard.By CTA examination,aneurysms were positive in 20 cases,negative in 40 cases,and missed in 1 case was the middle cerebral artery,the missed diagnosis rate was 4.76%(1/21).The diagnostic efficacy analysis showed that the sensitivity,specificity and accuracy of CTA in aneurysm diagnosis were 95.24%(20/21),97.44%(38/39)and 96.67%(58/60).There was no significant difference between CTA and DSA in aneurysm mouth diameter and aneurysm diameter(P>0.05).There was no significant difference between CTA and DSA in image quality(P>0.05).Conclusion:CTA has high diagnostic efficacy in aneurysm diagnosis,and the quality of measured data and image is close to the gold standard DSA.
