原发性蛛网膜下腔出血CT与数字减影血管造影技术的临床诊断价值

Clinical Value of CT and Digital Subtraction Angiography in Primary Subarachnoid Hemorrhage

目的:分析放射影像在临床诊断原发性蛛网膜下腔出血中的价值。方法:以2017年1月~2020年12月收治的70例原发性蛛网膜下腔出血患者为对象,经随机分组法分为2组进行研究,各组为35例。采取CT血管造影技术对参照组进行诊断,采取数字减影血管造影技术对试验组进行诊断。比较2组诊断阳性率、漏诊及误诊率、诊断费用。结果:2组对比诊断阳性率的数据表明试验组更高,满足统计要求(P<0.05)。2组对比漏诊及误诊率的数据表明试验组更低,满足统计要求(P<0.05)。2组对比诊断费用的数据表明试验组更高,满足统计要求(P<0.05)。结论:临床诊断原发性蛛网膜下腔出血中应用数字减影血管造影技术的检出率较高,但其费用更贵,因此在选择诊断方法时还需综合考虑患者实际情况。

Objective:To analyze the value of radiology in the clinical diagnosis of primary subarachnoid hemorrhage.Methods:70 patients with primary subarachnoid hemorrhage treated from January 2017 to December 2020 were randomly divided into two groups,with 35 cases in each group.The reference group was diagnosed by CT angiography,and the experimental group was diagnosed by digital subtraction angiography.The positive rate of diagnosis,the rate of missed diagnosis and misdiagnosis,and the cost of diagnosis were compared between the two groups.Results:The positive rate of the two groups showed that the experimental group was higher and met the statistical requirements(P<0.05).The data of missed diagnosis and misdiagnosis rate between the two groups showed that the experimental group was lower and met the statistical requirements(P<0.05).The data of diagnosis cost of the two groups showed that the experimental group was higher and met the statistical requirements(P<0.05).Conclusion:The detection rate of DSA in the clinical diagnosis of primary subarachnoid hemorrhage is higher,but its cost is more expensive,so the actual situation of patients should be taken into consideration when selecting the diagnosis method.
