软件和硬件的改进使得能够将双成像模式集成到混合系统中，这允许不同数据集的组合采集。将正电子发射断层扫描（PET）和计算机断层扫描（CT）扫描仪集成到PET/CT系统中已经显示出与独立采集的CT和PET图像相比在癌症患者的管理方面的改进。在已知或疑似冠状动脉疾病（CAD）患者中，采用单光子发射计算机断层扫描（SPECT）或PET结合CT的混合心脏成像可在单一环境中显示心脏和血管解剖结构异常及其生理后果，与单独或并行解读数据集相比，似乎可提供上级信息。混合系统也有利于患者，因为单短双数据采集。然而，混合心脏成像也产生了争议，关于哪些患者应该接受这种综合检查的临床效果和最小化的成本和辐射剂量，如果基于软件的融合图像单独获得将是一个有用的替代方案。欧洲核医学协会（EANM）、欧洲心脏放射学会（ESCR）和欧洲核心脏病学理事会（ECNC）在本文中希望就SPECT/CT和PET/CT混合心脏成像在已知或疑似CAD患者中的当前作用发表机构立场声明。
Improvements in software and hardware have enabled the integration of dual imaging modalities into hybrid systems, which allow combined acquisition of the different data sets. Integration of positron emission tomography (PET) and computed tomography (CT) scanners into PET/CT systems has shown improvement in the management of patients with cancer over stand-alone acquired CT and PET images. Hybrid cardiac imaging either with single photon emission computed tomography (SPECT) or PET combined with CT depicts cardiac and vascular anatomical abnormalities and their physiologic consequences in a single setting and appears to offer superior information compared with either stand-alone or side-by-side interpretation of the data sets in patients with known or suspected coronary artery disease (CAD). Hybrid systems are also advantageous for the patient because of the single short dual data acquisition. However, hybrid cardiac imaging has also generated controversy with regard to which patients should undergo such integrated examination for clinical effectiveness and minimization of costs and radiation dose, and if software-based fusion of images obtained separately would be a useful alternative. The European Association of Nuclear Medicine (EANM), the European Society of Cardiac Radiology (ESCR) and the European Council of Nuclear Cardiology (ECNC) in this paper want to present a position statement of the institutions on the current roles of SPECT/CT and PET/CT hybrid cardiac imaging in patients with known or suspected CAD.
