ABSTRACT=Objective: The purpose of this study was to examine the current state of the application of imaging in sleep research, as well as hotspots and trends. 
Materials and Methods: A search was conducted of the Web of Science Core Collection (WoSCC) between September 1, 2012, and August 31, 2022 for literature related to sleep imaging. This study analyzed 7679 articles published in this field over the past 10 years, using CiteSpace to analyze tendencies, countries, institutions, authors, and hotspots.
Results: There were 7679 articles on the application of imaging to sleep research published by 566 institutions located in 135 countries in 1428 journals; the number of articles was increasing on a yearly basis. According to keyword analysis, the research direction of the application of imaging in sleep research focused on the effects of degenerative diseases on sleep, such as Parkinson's disease, Alzheimer's disease, and small vessel disease. A literature evaluation found that Parkinson's disease, insomnia, sleep quality, and rapid eye movement sleep behaviour disorder were the top research trends in this field.
Conclusions: In the application of imaging in sleep research, magnetic resonance functional brain imaging represents a reliable research method. Additionally, a growing body of research has focused on sleep disorders caused by degenerative diseases. In the future, more aging-related diseases may be the subject of sleep-related research, and imaging could provide convenient and reliable evidence in this respect.
