PET/MR is a hybrid imaging technology with the potential to combine the molecular and functional information of PET with the soft-tissue contrast of MR. Herein we review the technical features and challenges of putting these different technologies together. We emphasize the conceptual to make the material accessible to a wide audience. We begin by reviewing PET/CT, a more mature multi-modality imaging technology, to provide a basis for comparison to the history of PET/MR development. We discuss the motivation and challenges of PET/MR and different approaches that have been used to meet the challenges. We conclude with a speculation about the future of this exciting imaging method.
正电子发射断层扫描/磁共振成像（PET/MR）是一种混合成像技术，有潜力将PET的分子和功能信息与MR的软组织对比度相结合。在此，我们回顾了将这些不同技术整合在一起的技术特点和挑战。我们强调概念性内容，以使广大读者能够理解相关材料。我们首先回顾PET/CT，一种更成熟的多模态成像技术，为与PET/MR发展历程进行比较提供基础。我们讨论了PET/MR的动机和挑战，以及为应对这些挑战所采用的不同方法。最后，我们对这种令人兴奋的成像方法的未来进行了展望。
