目的探讨分析64层螺旋CT诊断不同程度冠状动脉狭窄的临床价值。方法冠心病患者78例作为研究对象,并将64层螺旋CT诊断不同程度冠状动脉狭窄的结果与常规冠状动脉造影的诊断结果相比较,以总结分析64层螺旋CT诊断不同程度冠状动脉狭窄的临床价值。结果经分析发现,64层螺旋CT诊断结果中轻度冠状动脉狭窄、中度冠状动脉狭窄以及重度冠状动脉狭窄的敏感度分别为71.79%、74.36%、89.74%,特异性分别为97.44%、98.72%、96.15%,准确率分别为96.15%、92.31%、89.74%,与常规冠状动脉造影检查诊断结果的符合率为91.27%。结论 64层螺旋CT诊断不同程度冠状动脉狭窄具有较高的临床应用价值,且诊断的准确率高,是诊断不同程度冠状动脉狭窄的有效方法。
Objective To investigate the clinical value of 64-slice spiral CT in the diagnosis of coronary artery stenosis. Methods 78 patients with coronary heart disease as the research object, and 64-slice spiral CT diagnosis of different degrees of coronary artery stenosis results compared with the conventional coronary angiography diagnostic results compared to 64-slice spiral CT diagnosis of varying degrees of coronary artery stenosis clinical value. Results The results showed that the sensitivity of 64-slice spiral CT was 71.79%, 74.36% and 89.74% respectively in the diagnosis of mild coronary artery stenosis, moderate coronary artery stenosis and severe coronary artery stenosis. The specificity was 97.44% and 98.72 %, 96.15% respectively. The accuracy rate was 96.15%, 92.31% and 89.74% respectively. The coincidence rate with the diagnostic results of conventional coronary angiography was 91.27%. Conclusion The 64-slice spiral CT is of great value in the diagnosis of coronary artery stenosis with different degrees of accuracy and high accuracy of diagnosis. It is an effective method to diagnose coronary stenosis with different degrees.
