摘　　要：随着诊断和治疗在细胞水平、分子水平甚至基因水平的发展,诊断技术的发展趋势也逐步从宏观层面转向了分子层面。本文从闪烁晶体和探测器、图像的校正融合方面阐述了PET/MRI的研制进展,分析了其应用优势以及可能存在的伪影问题,指出PET/MRI具有广阔的发展空间和应用潜力,必将开创分子影像学的新时代。With the rapid development of early diagnosis and treatment at cellular level, molecular level and even gene level, the development trend of diagnostic techniques has been transformed from macro level to molecular level. This paper introduces the research progress of PET/MRI in the aspects of scintillation crystal and detector, and correction and fusion of images. In this paper, the application advantages and the possible problems of artifacts of PET/MRI are also discussed. This paper points out that PET/MRI which has expansive development space and utilization potentiality will really create a new era of molecular imaging.
