摘要： 目的 探讨颅内动脉瘤（CA）诊断中去骨减影CTA的临床应用价值。方法 于本院疑似CA患者中筛选50例作为研究对象，入组患者收集时间为2019年10月-2020年12月。两组患者均接受CT去骨减影（CTA）及数字减影血管造影（DSA）两种方法进行检查，以手术/血管介入栓塞结果为依据评价两种检验方法结果。结果 50例患者经手术/血管介入栓塞证实颅内动脉瘤共计42例。其中CTA检出38例，DSA检出40例。两种检查方法敏感度及准确度组间对比无明显统计学差异（P>0.05）。结论 CA选择CTA检查可获得准确结果，检查无创安全性理想，能够快速为临床提供可靠依据，临床价值显著值得推广应用。

[Abstract]Objective To evaluate the clinical value of subtraction CT angiography（CTA）in the diagnosis of intracranial aneurysms（CA）. Methods 50 patients with suspected Ca in our hospital were selected as the research objects，and the patients were collected from October 2019 to December 2020. Two groups of patients were examined by CT Subtraction Angiography（CTA）and digital subtraction angiography（DSA）. The results of two methods were evaluated according to the results of operation / vascular interventional embolization. Results there were 42 cases of intracranial aneurysms confirmed by operation / interventional embolization. Among them，38 cases were detected by CTA and 40 cases by DSA. There was no significant difference in sensitivity and accuracy between the two groups（P > 0.05）. Conclusion CTA examination can obtain accurate results，noninvasive safety is ideal，can quickly provide reliable basis for clinical，clinical value is significant，it is worthy of popularization and application.

CA是一種脑动脉腔内出现局限性异常扩大而导致动脉壁瘤突出而形成的病变。该疾病多为脑动脉管壁受压或者出现先天缺陷所导致，根据临床研究证实，该疾病是导致蛛网膜下腔出血的重要诱因，并且临床死亡率和残疾率均较高，需要引起临床的极大重视【1】。患者接受DSA检查可获得准确结果，但是检查费用较高价值禁忌症较多导致临床应用受限。尽早明确疾病情况是确保治疗效果及预后的关键【2】。为此，本次研究筛选本院收治的CA患者作为研究对象，重点研究CA诊断中CTA检查的临床价值，能够提升临床检验效率及质量。研究过程及结果报道如下。
