目的确定和比较负荷心肌灌注显像(mPI)诊断阻塞性冠状动脉疾病(cAD)的用途,使用常规冠状动脉造影(ccA)作为参考标准。方法检索了medline和Embase中用mRI评估mPI诊断冠心病的相关文献,并对比文献中用增强超声心动图(EcHO)、单光子发射计算机断层显像(SPEcT)和正电子发射体层摄影(PET)所做的相关研究。结果通过汇总分析所有资料基础上产生随机效应模型,文章中涉及mRI对2970例病人的28项研究和EcHO对1323例病人的13项研究,冠心病的诊断率至少在50%以上,通过常规ccA检查管腔狭窄至少在70%～75%。mRI诊断比值比的对数(3.63;95%cI:3.26～4.00)明显高于SPEcT(2.76;95%cI:2.28～3.25;P=0.006)及EcHO(2.83;95%cI:2.29～3.37;P=0.02)。而在SPEcT和EcHO间没有明显差异(P=0.52)。结论研究结果表明,在诊断冠心病方面mRI优于EcHO和SPEcT。EcHO和SPEcT没有明显差异。

Bi2Te3-based materials have drawn much attention from the thermoelectric community due to their excellent thermoelectric performance near room ***,the stability of existing n-type Bi2（Te,Se）3materials is still low due to the evaporation energy of Se (37.70 kJ mol-1) being much lower than that of Te (52.55 kJ mol-1).The evaporated Se from the material causes problems in interconnects of the module while degrading the efficiency.
