核素心肌灌注显像与多层螺旋CT对冠心病的诊断价值比较

目的 比较核素心肌灌注显像(SPECT)与多层螺旋CT冠脉成像(MSCT)诊断冠心病(CHD)的临床效果.方法 回顾性分析36例行SPECT与MSCT检查的拟诊CHD患者的临床资料,对两种检查方法的诊断效果进行对比.结果 SPECT敏感性为89.47％、特异性为94.12％、准确率为91.67％；MSCT敏感性为84.21％、特异性为94.12％、准确率为88.89％,两者的敏感性、特异性、准确率差异均无统计学意义(x2=1.265,1.668,2.005,1.526,1.889,均P＞0.05).结论 SPECT与MSCT诊断CHD有高度的一致性,两种检查方法结合应用可提高对CHD的诊断水平.

Comparison of radionuclide myocardial perfusion imaging and multilayer spiral CT in the diagnosis of 36 patients with coronary artery disease

Objective To compare the clinical effect of radionuclide myocardial perfusion imaging（SPECT） and multilayer spiral CT coronary artery imaging（MSCT） in the diagnosis of coronary artery disease（CHD）. Methods The clinical data of 36 patients suspected with CHD and routine inspection of SPECT and MSCT were retrospectively analyzed. The diagnostic effects of two methods were compared. Results The sensitivity, specificity and the rate of accuracy of SPECT was 89.47 % ,94.12 % , and 91.67 % , respectively, while the sensitivity, specificity and the rate of accuracy of MSCT was 84.21% ,94.12% ,and 88.89% ,respectively. There were no obvious difference in two groups （X2 = 1.265,1.668,2.005,1.526,1.889,all P〉0.05）. Conclusion There was a high degree consistency on the diagnosis of CHD between SPECT and MSCT. In the application, combined with the two methods could improve the diagnosis of CHD.
