Abstract: With its application to various fields, artificial intelligence (AI) has become a research hotspot in today's society. The current shortage of personnel in the medical industry and the increased rated of medical diagnosis are crucial for AI application in the medical industry, especially in imaging diagnosis. AI-assisted diagnosis can improve the detection rate of diseases, provide effective diagnostic and treatment information for clinicians, and reduce the repetitive work of imaging physicians, thereby saving time for the research of difficult cases. In this paper, medical imaging AI is briefly introduced, and the latest and most influential research results at home and abroad are combined to explore the new development of medical imaging AI.
