吞咽是一种复杂的运动过程，涉及多个脑区和神经网络。许多中枢神经系统疾病都会导致吞咽困 难。功能磁共振成像（functional magnetic resonance imaging，fMRI）技术可以显示中枢神经系统结构和功能 的关系，磁共振弥散张量成像（diffusion tensor imaging，DTI）可清晰地观测大脑白质纤维束的完整性。本文 综述了关于吞咽功能和吞咽障碍的多模态磁共振成像研究的相关文献。

Swallowing is a complex motor process that involves multiple brain regions and neural networks. Central nervous system diseases can lead to dysphagia. Functional magnetic resonance imaging(fMRI) displays the relationship between the structure and function of the central nervous system, while diffusion tensor imaging(DTI) provides clear observation of the integrity of brain white matter fibers. This article reviews the relevant literature on multimodal magnetic resonance imaging research on swallowing and dysphagia.
