分子核医学显像展望：多参数分子显像时代

The development of nuclear medicine molecular imaging： An era of multiparametric imaging

核医学分子显像呈多模式、多示踪剂发展趋势，不同显像模式、不同显像示踪剂带来的多参数信息为临床和实验室的研究提供了更丰富的互补信息。其中，PET—MRI将成为核医学分子显像未来发展的一个热门话题。该文着重探讨了核医学分子显像发展过程中，由单模式到多模式、由单示踪剂到多示踪剂的演变过程，总结多模式、多示踪剂、多参数分子显像的定义、区别、优缺点和存在问题，并探讨了分子显像的未来发展。

Nuclear medical molecular imaging is developing toward a multimodality and multitracer future. Abundant complementary data generated from different tracers in different modalities are successfully serving the biological research and clinical treatment. Among the others, PET-MRI has the greatest potential and will be a research of interest in the near future. This article focused on the evolution history of nuclear medicine from single modality to multimodality, single tracer to muhitracer. It also gave a brief summary to the identifications, differences, pros and consofmultimodality, multitraeer, multiparametric molecular imaging. Issues, problems and challenges concerned with her development and recognition are also discussed.
