双源CT 冠状动脉血管成像对冠状动脉狭窄的诊断价值分析

Analysis of the diagnostic value of dual-source CT coronary angiography for coronary artery stenosis

目的:探讨应用双源CT冠状动脉血管成像(DSCT-CA)的检查方式对诊断冠状动脉狭窄的价值。方法:选取2019年1月—2020年5月期间我院65例疑似冠状动脉狭窄的患者,均接受冠脉造影(CAG)与DSCT-CA检查,以CAG检查为金标准,评价DSCT-CA对狭窄情况的诊断价值,并且以冠状动脉狭窄50%为界限,分析DSCT-CA诊断的准确度、敏感度及特异度。结果:检出595个冠状动脉节段,经CAG检出狭窄节段158个(26.55%),经DSCT-CA检出狭窄节段142个(23.87%);经DSCT-CA对冠状动脉狭窄50%的诊断准确度为96.92%(63/65)、敏感度为100.00%(47/47)、特异度为88.89%(16/18)。结论:应用DSCT-CA可对不同程度的冠状动脉狭窄的诊断价值显著,值得推广。

Objective To explore the value of dual-source CT coronary angiography(DSCT-CA)in the diagnosis of coronary artery stenosis.Methods From January 2019 to May 2020,selected 65 patients with suspected coronary artery stenosis from our hospital,all underwent coronary angiography(CAG)and DSCT-CA examination.The CAG examination was used as the gold standard to evaluate the diagnostic value of DSCT-CA for stenosis,and coronary artery stenosis 50%Is the limit to analyze the accuracy,sensitivity and specificity of the diagnosis of DSCT-CA.Results 595 coronary artery segments were detected,158(26.55%)stenosis segments were detected by CAG,142(23.87%)stenosis segments were detected by DSCT-CA;coronary artery stenosis was detected by DSCT-CA 50%Diagnostic accuracy is 96.92%(63/65),sensitivity is 100.00%(47/47),and specificity is 88.89%(16/18).Conclusion The application of DSCT-CA can be of great value in diagnosing different degrees of coronary artery stenosis and is worthy of promotion.
