Myocardial perfusion imaging (MPI) has enjoyed considerable success for decades due to its diagnostic accuracy and wealth of prognostic data. Despite this success several limitations such as lengthy protocols and radiation exposure remain. Advancements to address these shortcomings include abbreviated stress-only MPI (SO MPI) protocols, PET and both hardware and software methods to reduce radiation exposure and time. SO MPI has advantages in protocol time and radiation reduction with a wealth of supporting data in terms of diagnostic validity and prognostic value. Newer technologies such as attenuation correction, and advanced camera technologies have enabled SO MPI to be more efficient in reducing the time of acquisition and radiation dose and improving accuracy. This review examines the literature available, regarding accuracy, patient outcomes, implementation strategies, and newer developments associated with SO MPI.
几十年来，心肌灌注成像（MPI）因其诊断准确性和丰富的预后数据而取得了巨大成功。尽管如此，它仍存在一些局限性，如检查流程冗长和辐射暴露。为解决这些缺点所取得的进展包括简化的仅负荷MPI（SO MPI）检查流程、PET以及减少辐射暴露和检查时间的硬件和软件方法。SO MPI在检查时间和辐射减少方面具有优势，在诊断有效性和预后价值方面有大量支持数据。诸如衰减校正和先进相机技术等新技术使SO MPI在减少采集时间和辐射剂量以及提高准确性方面更有效率。本综述研究了现有的关于SO MPI的准确性、患者预后、实施策略和新进展的文献。
