摘　　要：第107届北美放射学会(Radiological Society of North America,RSNA)年会关于中枢神经影像学的研究亮点主要有:(1)脑肿瘤:基因分子诊断分类与预测,治疗后病情评估;(2)脑卒中:MRI血管壁成像(vessel wall imaging,VWI)技术的优势,鼓励提升VWI的图像质量和临床应用,人工智能(artificial intelligence,AI)大大提升了急性出血性卒中和缺血性卒中的影像诊断水平和效率;(3)脑发育和认知功能障碍:应用AI分析脑结构和功能成像更高效、更准确评估和预测脑发育及脑认知;(4)脑成像技术优化:AI助力影像技术创新,提升图像质量和减少对比剂用量;(5)超高场MRI:11.7 T MRI面世不断刷新着磁共振场强和分辨率的极限,将重新定义人脑解剖以及开辟更多崭新的研究领域;(6)新型冠状病毒肺炎与中枢神经系统。第107届RSNA年会主题为“重新定义放射学”,随着技术的优化、研究领域的创新和科技人文的结合,神经影像也将重新定义为以人为本的智能神经影像。本文将对相关研究进展进行综述。The highlights about neuroimaging at the 107;scientific assembly and annual meeting of Radiological Society of North America(RSNA) were:(1) Brain tumor: the meeting highlighted the genotyping and prediction of brain tumor and follow-up evaluation;(2) Stroke: the advantages of MRI vessel wall imaging(VWI) were stressed, and the imaging quality and clinical application of VWI should be promoted. Artificial intelligence(AI) has greatly improved the imaging diagnosis and efficiency of acute hemorrhagic and ischemic stroke;(3) Brain development and cognitive dysfunction: structural and functional MRI combined with AI could optimize imaging assessment and prediction with higher efficiency and accuracy;(4) Technical optimization of brain imaging: AI has empowered the imaging technology to image quality enhancement and contrast agent reduction;(5) High-field MRI: 11.7 T MRI has been upgrading the MRI intensity and spatial revolution, which can redefine the brain anatomy and open new research dimensions;(6) Corona virus disease 2019(COVID-19) and central nervous system. The main topic of the 107;RSNA is "Redefining Radiology". With the technical promotion, research innovation as well as the merging of science and humanity, neuroimaging will be redefined as a people-oriented and intelligent field. This article summarizes the relevant research progress.
