SPECT lung scans show low clot risk at three months, suggesting a potential alternative to CT in pulmonary embolism diagnosis ...

为解决冠状动脉疾病（CAD）无创功能评估的临床需求，研究人员在埃及首次开展了一项头对头比较研究，对比了CT衍生的血流储备分数（FFR-CT）与单光子发射计算机断层扫描（SPECT）在诊断心肌缺血中的表现。结果表明，FFR-CT在患者水平和主要冠状动脉（LAD、LCx）水平上均表现出高诊断准确性，可作为SPECT的有效替代方案，并为避免不必要的侵入性血管造影提供了可靠“守门人”。
