Magnetic resonance imaging (MRI) has become an important tool in the investigation of cerebral abnormalities associated with psychiatric illnesses. There are a number of benefits of investigating psychiatric illness with MRI, which is superior to computed tomography scanning. MRI has been used to study neurologic deficits seen in schizophrenia, affective disorders, dementia, and more recently, anxiety disorders. Magnetic resonance spectroscopy offers a new investigational technique that adds functional information to the structural changes seen with standard MRI scanning. This review highlights the current data in living human subjects that demonstrate structural changes in psychiatric disorders using MRI, including recent studies of the anxiety disorders.
磁共振成像（MRI）已成为研究与精神疾病相关的脑部异常的重要工具。使用MRI研究精神疾病有诸多益处，它优于计算机断层扫描。MRI已被用于研究精神分裂症、情感障碍、痴呆以及最近的焦虑症中出现的神经功能缺损。磁共振波谱提供了一种新的研究技术，能为标准MRI扫描所见的结构变化增添功能信息。这篇综述重点介绍了目前在活体人类受试者中利用MRI证明精神疾病结构变化的数据，包括最近关于焦虑症的研究。
