摘　　要：多模态成像系统虽已应用于临床,但PET-MRI的出现是医学影像学的革命性进步,是继PET-CT之后具有里程碑意义的影像设备。MRI不但解决了CT检查中的部分局限性,还可提供丰富的形态学和功能信息,而PET在分子功能和代谢水平对人体生理及疾病状态方面进行研究的同时,还可在肿瘤、心血管疾病和神经系统疾病的诊断、治疗决策、疗效评价及预后评估中起到重要的作用。Even though multimodal imaging system has already been applied in clinic, the PET-MRI still is a revolutionary progress of medical imaging, and it is a landmark after PETCT imaging equipment. MRI not only can solve the limitations of CT, but also can provide abundant morphology and function information; at the same time, PET also play important role in the diagnosis of tumor, nervous system diseases and cardiovascular disease; and in the treatment decision, treatment effect evaluation and prognosis evaluation when it is applied in research of physiological and disease state at the levels of molecular activity and metabolism of human body. With the rapid development of science and technology, this article has summarized the imaging technology and clinical application of PET-MRI in recent years.
