放射性核素心肌灌注显像（MPI）在冠心病的诊断和治疗中起着重要作用。然而，由于MPI在2000年代中期急剧增长，对MPI使用不当和成像相关辐射暴露的担忧增加。作为回应，专业协会为MPI制定了适当的使用标准。与此同时，新技术、传统扫描仪的图像重建软件和专用心脏扫描仪的出现促进了MPI与低剂量和超低剂量放射性示踪剂的性能。本文提供了一种实用的方法来执行低辐射剂量MPI使用传统的和新的技术。
Radionuclide myocardial perfusion imaging (MPI) plays a vital role in the evaluation and management of patients with coronary artery disease. However, because of a steep growth in MPI in the mid 2000s, concerns about inappropriate use of MPI and imaging-related radiation exposure increased. In response, the professional societies developed appropriate-use criteria for MPI. Simultaneously, novel technology, image-reconstruction software for traditional scanners, and dedicated cardiac scanners emerged and facilitated the performance of MPI with low-dose and ultra-low-dose radiotracers. This paper provides a practical approach to performing low-radiation-dose MPI using traditional and novel technologies.
