PET/CT 和其他组合扫描仪在过去十年中迅速成为重要的研究工具，并被证明对于改进常规核医学的诊断具有不可估量的价值。混合 PET/MR 扫描仪的设计提出了艰巨的技术挑战，这些仪器最近才被引入市场。最初对这些扫描仪性能的期望很高，特别是因为 MR 模式固有的卓越组织对比度的潜力，以及与 PET 结合的多参数功能成像的潜力。然而，这些新系统可能给心脏领域带来的附加价值和潜在临床作用尚未得到证实。本综述对 PET 和 MR 在心脏病学领域的现有应用进行了比较总结，并提出了利用新推出的组合仪器的独特性能的潜在心脏应用。
PET/CT and other combined scanners have in the past decade rapidly emerged as important research tools and are proving to be invaluable for improved diagnostics in routine nuclear medicine. The design of hybrid PET/MR scanners presented a formidable technical challenge, and only recently were these instruments introduced to the market. Initial expectations of the performance of these scanners have been high, notably because of the potential for superior tissue contrast inherent in the MR modality, as well as the potential for multiparametric functional imaging in conjunction with PET. However, the additional value and potential clinical role that these new systems might bring to the cardiac field have yet to be documented. This review presents a comparative summary of the existing applications for PET and MR in the field of cardiology and suggests potential cardiac applications exploiting unique properties of the newly introduced combined instrumentation.
