目的：探讨13 N-NH3 PET腺苷负荷-静息心肌灌注显像（ MPI）在疑诊或确诊冠心病患者冠脉病变功能学评价中的应用价值。方法30例疑似或确诊的冠心病患者，均接受13N-NH3PET腺苷负荷-静息MPI和冠状动脉造影（ CAG）检查。结果用13 N-NH3 PET腺苷负荷-静息MPI评估30例患者197个冠状动脉节段供血区，结果50个节段供血区确定为存活心肌（24个节段供血区发现可逆性灌注缺损，26个节段供血区呈固定性灌注缺损），3个节段供血区确定为无存活心肌，其余144个节段供血区为正常心肌。以CAG发现≥50％狭窄为CAG检查结果阳性标准，30例中MPI与CAG结果相符合者24例。阳性22例、假阳性5例、假阴性1例、阴性2例。敏感度95．65％、特异度28．57％、阳性预测值81．48％、阴性预测值66．67％。以CAG发现≥75％狭窄为CAG阳性标准，30例中MPI结果与CAG结果相符合者25例。其中阳性22例、假阳性5例、假阴性0例、阴性3例。敏感度为100％、特异度为37．5％、阳性预测值为81．48％、阴性预测值为100％。结论 MPI用于疑似或确诊冠心病患者冠状动脉功能学评价效果较好。

Objective To explore the value of 13 N-NH3 PET adenosine stress -resting myocardial perfusion imaging ( MPI) in the diagnosis of coronary heart disease, coronary artery lesions function to evaluate the feasibility of learning. Methods 0patientswithcoronaryheartdisease(CHD)weredetectedwith13N-NH3PETadenosinestress-restingandcor-onary angiography.Method 30 cases of patients with two day MPI.All patients were performed coronary angiography in 1 months.Results On the basis of coronary angiography found 50%or more narrow,the sensitivity of MPI was 95.65%,spe-cific degrees was 28.57%,positive predictive value was 81.48%,negative predictive value was 66.67%.On the basis of cor-onary angiography found 75%or more narrow,the sensitivity of MPI was 100%,specific degrees was 37.5%,positive predic-tive value was 81.48%,negative predictive value was 100%. Conclusion MPI can serve as effective index of the diagnosis of CHD, is also a very good function of coronary artery evaluation index.
