256排螺旋CT冠脉成像技术与常规冠脉造影的准确度对比

目的探究256排螺旋CT冠脉成像技术与常规冠脉造影的准确度。方法择取2017年5月至2019年10月我院收治的冠心病患者148例,依据诊断方式不同划分为两组即研究组与对照组,每组74例,以作研究对象。对照组采用常规冠脉造影诊断,研究组则采用256排螺旋CT冠脉成像技术诊断,分析两组诊断冠脉管腔狭窄程度,特异性、敏感性及准确性,冠脉血管中斑块性质,漏诊率及误诊率,诊断时间及诊断费用。结果研究组冠脉管腔狭窄Ⅰ级、Ⅱ级发生率低于对照组(P>0.05);研究组冠脉管腔狭窄Ⅲ级、Ⅳ级、Ⅴ级发生率高于对照组(P<0.05);研究组敏感性、特异性、准确度均高于对照组(P<0.05);研究组纤维斑块、钙化斑块、软斑块及混合斑块诊断准率高于对照组(P<0.05);研究组误诊率、漏诊率均低于对照组(P<0.05);研究组诊断时间及费用低于对照组(P<0.05),研究组患者诊断满意度高于对照组(P<0.05)。结论临床诊断冠心病等疾病采用256排螺旋CT冠脉成像技术的敏感性强、特异性及准确度高,可有效诊断冠脉管腔狭窄程度及其中斑块性质,避免误诊及漏诊情况发生,值得在临床诊断中应用及深入研究。

Comparison of Accuracy of 256-Slice Spiral CT Coronary Angiography and Conventional Coronary Angiography

Objective To investigate the accuracy of 256-slice spiral CT coronary angiography and conventional coronary angiography.Methods 148 patients with coronary heart disease admitted to our hospital from May 2017 to October 2019 were selected and divided into two groups according to different diagnostic methods,namely the study group and the control group,with 74 patients in each group as the research objects.The control group was diagnosed by conventional coronary angiography,while the study group was diagnosed by 256-slice spiral CT coronary angiography.specificity,sensitivity and accuracy;Plaque properties in coronary arteries;Missed diagnosis rate and misdiagnosis rate;Diagnosis time and cost.Results The team coronary vascular lumenⅠ,Ⅱoccurence rate is lower than the control group(P>0.05),the team champions vascular lumenⅢ,Ⅳ,Ⅴincidence is higher than the control group(P<0.05);The sensitivity,specificity and accuracy of the study group were higher than that of the control group(P<0.05).The diagnostic accuracy of fibrous plaque,calcification plaque,soft plaque and mixed plaque in the study group was higher than that in the control group(P<0.05).The rate of misdiagnosis and missed diagnosis in the study group was lower than that in the control group(P<0.05).The time and cost of diagnosis in the study group were lower than that in the control group(P<0.05),and the satisfaction of diagnosis in the study group was higher than that in the control group(P<0.05).Conclusion The 256-slice spiral CT coronary artery imaging technique is highly sensitive,specific and accurate in the clinical diagnosis of coronary heart disease and other diseases,which can effectively diagnose the degree of coronary stenosis and the nature of plaque,avoid misdiagnosis and missed diagnosis,and is worthy of clinical application and in-depth study.
