多层螺旋CT冠脉造影在心脏血管狭窄中的应用价值

Multi Slice Spiral CT Coronary Angiography in the Diagnosis of Cardiac Vascular Stenosis

目的探讨多层螺旋CT冠脉造影(CTA)在心脏血管狭窄中的诊断情况。方法收集2019年3月至2022年5月在本院进行CTA、数字减影全脑血管造影术(DSA)检查的患者86例,以DSA检查为金标准,统计CTA检查技术的诊断效能。结果经CTA技术检查后,灵敏度为92%、特异度为81.82%、阳性预测值为97.18%、阴性预测值为60.00%、准确度为90.70%。结论CTA在心脏血管狭窄具有较好的诊断效能,值得在临床上推广应用。

Objective To investigate the diagnosis of coronary artery stenosis with multi-slice spiral CT(CTA).Methods A total of 86 patients who underwent CTA and digital subtraction cerebrovascular angiography(DSA)examination in our hospital from March 2019 to May 2022 were collected.The diagnostic efficacy of CTA examination technology was analyzed using DSA examination as the gold standard.Results The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of DSA were 92%,81.82%,97.18%,60.00%,90.70%,respectively.Conclusion CTA has a good diagnostic efficacy in the diagnosis of cardiac vascular stenosis,and is worthy of clinical application.
