PET-MR在脑神经系统疾病中的应用现状及展望

PET-MR imaging in cranial nerve system disease: present applications and prospects for the future

单一核医学功能影像包括SPECT和PET,由于其自身的缺陷而不能充分满足临床的诊断需求,继而整合解剖与功能影像为一体的多模态成像设备成为核医学乃至整个影像学发展的趋势,继最早的SPECT-CT、PET-CT之后,目前最新研发的PET-MR已开始应用于临床,其中前两者已在临床上得到广泛的应用,而具有高组织分辨率的MR影像结合PET功能影像的PETMR,势必会对脑神经系统、心血管系统及肿瘤等疾病的诊断起到重要作用。

Single nuclear medicine functional imaging（including SPECT and PET） couldn’t fully meet the demand of clinical diagnosis because of its own limits, thus the multimodality imaging equipment integrated anatomical and functional images has became the development trend of the nuclear medicine and even the entire medical imaging. Following the earliest SPECT-CT and PET-CT which having been widely used in clinic, the newest PET-MR has also been applied to clinical practice. PET-MR combined MR images with PET function image is substantial to the clinical diagnosis of cerebral nervous system diseases, cardiovascular system diseases and tumor, etc. In this paper, we reviewed the current application situation and prospects of PET-MR in cerebral nervous system diseases.
