磁共振技术在术后谵妄中的应用

The application of magnetic resonance imaging in postoperative delirium

术后谵妄是一种在老年患者中较为常见的术后并发症，其发生机制与多种因素相关。截止目前，术后谵妄的神经基础尚不明确，且其是否进展为阿尔兹海默病也存在争议。磁共振技术作为无创、可以定量分析脑部结构和功能的研究方法，近年被逐步应用于各种神经精神类疾病。本文主要对磁共振技术在术后谵妄研究中的应用进行综述。

Postoperative delirium is one of the most common postoperative complications in elderly patients, and its pathogeny is related to many factors. Up to now, the neural basis of postoperative delirium is unclear, and whether it will develop to Alzheimer′s disease is controversial. Magnetic resonance imaging （MRI）, as a noninvasive and quantitative method for the analysis of brain structures and functions, has been gradually applied to a variety of neuropsychopathic disorders in recent years. The purpose of this study is to investigate the use of MRI in the studies of postoperative delirium.
