【摘要】 目的:探讨99mTc-MIBI心肌断层显像(SPECT)诊断冠心病(CAD)的临床价值。方法:60例患者同时进行99mTc-MIBI心肌断层显像(SPECT)和冠状动脉造影(CAG)检查,将结果进行对比分析。结果:以CAG为标准,SPECT诊断冠心病的敏感性93·18%,特异性50%,准确性指数81·67%,阳性预测值83·67%,阴性预测值72·73%。结论:SPECT与CAG从不同的角度诊断CAD符合率高。若CAG阳性则冠心病诊断成立,CAG与SPECT均阴性,可排除冠心病。更多还原

【Abstract】 Objective:To study the clinical value of SPECT ~ 99m Tc-MIBI myocardial perfusion imaging(SPECT)on the diagnosis of coronary artery disease(CAD).Methods:Sixty cases were checked with SPECT and coronaey artery angiography(CAG),Clinical datd of all patients were analyzed.Results:Compared with CAG,the sensitivity of the diagnosis of CAD with SPECT was 93.18%,the specificity 50%,the accurate index 81.67%,the positive 83.67%,and the negative 72.7%.Conclusion:SPECT comparing with CAG,from different diagnostic point of view,had higher coincidence rate.Assuming that the result of CAG was positive,CAD can be diagnosed,and if CAG and SPECT were both negative,CAD could be excluded.更多还原
