摘　　要：目的探讨单光子发射型计算机断层(SPECT)心肌灌注显像与冠状动脉CT血管成像(CCTA)诊断冠心病心肌缺血的临床价值。方法42例疑似冠心病心肌缺血患者均进行CCTA检查与SPECT心肌灌注显像检查。以冠状动脉造影结果为金标准,分别根据患者例数诊断结果及冠状动脉支数诊断结果,比较CCTA检查与SPECT心肌灌注显像检查对诊断冠心病心肌缺血的准确率、灵敏度、特异度。结果CCTA根据患者例数对诊断冠心病心肌缺血的准确率、灵敏度、特异度分别为88.10%、96.88%、60.00%;SPECT心肌灌注显像根据患者例数对诊断冠心病心肌缺血的准确度、灵敏度、特异度分别为85.71%、84.38%、90.00%。两种诊断方法根据患者例数对诊断冠心病心肌缺血的准确度、灵敏度、特异度比较,差异无统计学意义(P>0.05)。CCTA根据冠状动脉支数对诊断冠心病心肌缺血的准确度、灵敏度、特异度分别为82.54%、93.44%、73.31%;SPECT心肌灌注显像根据冠状动脉支数对诊断冠心病心肌缺血的准确度、灵敏度、特异度分别为84.92%、78.69%、90.77%。两种诊断方法根据冠状动脉支数诊断冠心病心肌缺血的准确度比较,差异无统计学意义(P>0.05)。CCTA根据冠状动脉支数诊断冠心病心肌缺血的灵敏度高于SPECT心肌灌注显像,诊断特异度低于SPECT心肌灌注显像,差异均有统计学意义(P<0.05)。结论对冠心病心肌缺血采用SPECT心肌灌注显像和CCTA诊断均有一定应用价值,SPECT心肌灌注显像特异度高,CCTA诊断灵敏度高,互为补充,可综合应用。Objective To discuss the clinical value of single photon emission computed tomography(SPECT) myocardial perfusion imaging and coronary computed tomography angiography(CCTA) in the diagnosis of myocardial ischemia in coronary heart disease. Methods All 42 patients with suspected myocardial ischemia coronary heart disease underwent CCTA and SPECT myocardial perfusion imaging. Taking coronary angiography as the gold standard, the accuracy, sensitivity and specificity of CCTA and SPECT myocardial perfusion imaging for the diagnosis of myocardial ischemia in coronary artery disease were compared based on the diagnostic results of the number of patients and the number of coronary artery branches. Results According to the number of patients, the accuracy, sensitivity and specificity of CCTA in diagnosing myocardial ischemia in coronary heart disease were 88.10%, 96.88% and 60.00%, respectively;the accuracy, sensitivity and specificity of SPECT myocardial perfusion imaging in the diagnosis of myocardial ischemia in coronary heart disease were 85.71%,84.38% and 90.00%, respectively. Comparison of the accuracy, sensitivity, and specificity of the two diagnostic methods for the diagnosis of myocardial ischemia in coronary artery disease according to the number of patients,the difference was not statistically significant(P>0.05). According to the number of coronary artery branches, the accuracy, sensitivity and specificity of CCTA in diagnosing myocardial ischemia in coronary heart disease were 82.54%, 93.44% and 73.31%;the accuracy, sensitivity and specificity of CCTA in diagnosing myocardial ischemia in coronary heart disease were 84.92%, 78.69% and 90.77%. Comparison of the accuracy of the two diagnostic methods for the diagnosis of myocardial ischemia in coronary artery disease according to the number of coronary artery branches, the difference was not statistically significant(P>0.05). The sensitivity of CCTA in diagnosing myocardial ischemia in coronary heart disease according to the number of coronary artery branches
