Functional magnetic resonance imaging and postoperative cognitive dysfunction

In recent years, the development of functional magnetic resonance imaging (fMRI) in the field of neurology and psychiatry has provided new thoughts for determining the objective diagnostic indicators of postoperative cognitive dysfunction (POCD). This paper introduces the current application of fMRI in the field of POCD both in theory and practice, and provides supports for future exploration and practice. This paper overviews fMRI and its application in neurological and psychiatric diseases, analyzes the theoretical feasibility and technical advantages of fMRI for POCD, lists the current research achievements, and discusses the limits in practice. With the continuous improvement of technology, deepening of application and conduct of joint research, fMRI′s predictive and diagnostic value for POCD will become increasingly prominent in clinical practice. Key words: Functional magnetic resonance imaging; Postoperative cognitive dysfunction
