| 目的比较 99m锝( 99mTC)单光子发射计算机断层成像术( SPECT)心肌显像与冠状动脉数字减影血管造影( DSA)诊断冠心病( CHD)的价值，探讨诊断心肌缺血与心肌梗死的有效途径。方法选取 2016年 1月至 2019年 1月第一作者在安庆市立医院工作及安徽省立医院进修期间临床拟诊为冠心病进行诊治的 108例病人中抽出做过冠脉造影( CAG)的病人 13例，均行 99mTC SPECT心肌运动负荷灌注显像，次日( 24 h后)负荷显像诊断为阳性的 12例行 99mTC SPECT心肌静息灌注显像。结果确诊的 13例冠心病中 5例为心肌梗死， 5例为心肌缺血， 1例为 X综合征， 2例正常。 CAG诊断结果， 5例为心肌梗死， 5例为心肌缺血， 3例正常。运动负荷心肌显像诊断结果，心肌缺血 12例， 1例正常；诊断为心肌缺血的 12例做了静息心肌显像，结果静息+运动心肌显像诊断 6例为心肌梗死， 6例为心肌缺血， 1例正常。 SPECT显像诊断 1例为假阳性， 1例假阴性， CAG诊断 2例假阴性， 1例假阳性。 SPECT阳性率为 92.3％， CAG为 76.9％； SPECT准确率为 84.6％， CAG为 76.9％。结论 99mTC SPECT心肌显像与 CAG对照诊断，重点分析不同，优势互补，综合评估，冠心病的诊断准确率大大提高，两者对比诊断有很高的临床应用价值。 |

| Objective Compare the value of 99mTC single photon emission computed tomography (SPECT) myocardial imaging andcoronary digital subtraction angiography (DSA) in diagnosing coronary heart disease (CHD), and explore effective ways to diagnose myocardial ischemia and myocardial infarction.Methods From January 2016 to January 2019,among 108 patients to be diagnosed andtreated for coronary heart disease, 13 patients who had undergone coronary angiography(CAG) were selected retrospectively, all ofwhom received myocardial perfusion imaging received resting myocardial perfusion imaging, while 1 patients who were diagnosed asnegative did not receive resting myocardial perfusion imaging.Results 99mTC SPECT myocardial resting and exercise load imaging can directly show the azimuth-area size and degree of myocardial ischemia. It has very special clinical significance in the risk assessment and post-treatment evaluation of coronary heart disease, but there are also many factors causing false positive or false negative. Although DSA is the gold standard for coronary artery examination, it can′t reflect the stenosis of very small coronary vessels, so both ofthem have certain advantages and disadvantages. In this study, the inconsistencies were identified,and combined with a variety of clinical data,the accuracy of the diagnosis of coronary heart disease were significantly improved.Conclusion The comparative diagnosis of 99mTC SPECT myocardial imaging,and focus on differences,coronary angiography results is complementary, comprehensive evaluation,the diagnosisa ccuracy of coronary heart disease is greatly improved, and the comparative diagnosis of the two has high clinical application value. |
