| 摘 要： |
| 消化道动力障碍是胃食管反流病、胃轻瘫、功能性消化不良等疾病的核心病理生理机制，磁共振成像（MRI）技术凭借其无创、无辐射、多参数动态成像以及兼顾解剖和功能评估的独特优势，为胃动力评估提供了全新工具，符合临床精准诊疗的发展趋势。本文就MRI在胃动力评估中的技术创新、临床应用和研究进展作一系统综述，并分析其临床应用价值和当前存在的局限性，从而为相关疾病的诊疗实践和科研创新提供有益参考。 |

| Abstract: |
| Gastrointestinal motility disorders represent a core pathophysiological mechanism underlying diseases such as gastroesophageal reflux disease, gastroparesis, and functional dyspepsia. Magnetic resonance imaging (MRI), with its unique advantages of being non-invasive, radiation-free, capable of multi-parametric dynamic imaging, and providing both anatomical and functional assessment, offers a novel approach for evaluating gastric motility, which conforms to the developmental trend of precise clinical diagnosis and treatment. This article systematically reviewed the technological innovations, clinical applications, and research progress of MRI-based gastric motility assessment, and further discussed the clinical value and current limitations of this methodology, aiming to provide valuable insights for both clinical practice and scientific research in related fields. |
