SPECT和MRI诊断冠心病心肌缺血的临床价值分析

Clinical Value of SPECT and MRI in the Diagnosis of Myocardial Ischemia of Coronary Heart Disease

目的探讨单光子发射计算机体层显像(SPECT)和磁共振成像(MRI)诊断冠心病心肌缺血的临床价值。方法回顾性分析2015年6月至2018年6月间收治的94例冠心病患者临床资料,所有患者均行SPECT和MRI检查。比较不同检查方法诊断冠心病的准确率,评估不同检查方法诊断冠心病心肌缺血、心肌活性的效能。结果SPECT、MRI冠心病诊断准确率对比,差异无统计学意义(P>0.05);SPECT、MRI诊断心肌缺血灵敏度、特异度差异无统计学意义(P>0.05);MRI诊断心肌缺血准确率高于SPECT(P<0.05);MRI诊断心肌活性的灵敏度、准确率高于SPECT(P<0.05)。MRI、SPECT诊断心肌活性的特异性对比,差异无统计学意义(P>0.05)。结论SPECT和MRI均是能有效无创性诊断冠心病心肌缺血的无创检查技术,MRI诊断在心肌缺血和心肌活性的方面诊断效能更高。

Objective To explore the clinical value of single photon emission computed tomography(SPECT)and magnetic resonance imaging(MRI)in the diagnosis of myocardial ischemia of coronary heart disease.Methods The clinical data of 94 patients with coronary heart disease admitted from June 2015 to June 2018 were retrospectively analyzed retrospectively.All patients were given SPECT and MRI examination.The accuracy rate of different examination methods in the diagnosis of coronary heart disease was compared,and the efficacy of different examination methods in the diagnosis of myocardial ischemia and myocardial activity in coronary heart disease was evaluated.Results There was no statistically significant difference in the diagnostic accuracy of SPECT and MRI for coronary heart disease(P>0.05).There were no significant differences in the sensitivity and specificity of myocardial ischemia diagnosed by SPECT and MRI(P>0.05).The accuracy of MRI in the diagnosis of myocardial ischemia was higher than that of SPECT(P<0.05).The sensitivity and accuracy of MRI for myocardial activity were higher than those of SPECT(P<0.05).There was no significant difference in the specificity of MRI and SPECT for myocardial activity(P>0.05).Conclusion Both of SPECT and MRI are effective non-invasive techniques for the diagnosis of myocardial ischemia of coronary heart disease.MRI has higher efficacy in diagnosing myocardial ischemia and myocardial activity.
