MRI评估胃动力的研究进展

The recent advance in the assessment of gastric motility by MRI

随着生活工作压力的增大,胃动力紊乱的发病率呈逐年增长趋势,而胃动力紊乱的主要原因是功能性消化不良,因此胃动力检测有助于功能性胃肠道疾病的诊断和治疗。近几年,MRI新技术和新软件的研发以及随着其在胃肠道疾病诊断方面研究的快速发展,通过使用组织对比剂可获得胃肠道高分辨率图像。目前,大多数研究是在证实该技术在临床应用中的价值及研发数据处理技术,新软件研发可以克服运动伪影,提高图像质量,便于诊断评价。MRI检查技术具有无创伤、无电离辐射、多平面成像等优势,广泛适用于需要重复检查的患者。但是,目前该技术仍未能在胃肠道动力评价中广泛应用。该文主要对胃动力不同检查技术进行比较及MRI评价胃动力方面研究进展进行阐述。

With the growing stress at work as well as personal life, the morbidity rate of gastric dynamic disorder for modern people has been increasing annually. The main cause of the disorder is functional dyspepsia, in the meanwhile, detection of gastric motility will facilitate the diagnosis and treatment of functional gastrointestinal diseases. In recent years, with the help of MRI technology development and new computer softwares, we are able to obtain high-resolution images of the gastrointestinal tract by using contract agent. At present, most research is to confrm and to development softwares for image data processing. The research and development of new computer software can overcome motion artifact, improve image quality, and facilitate diagnosis as well. The noninvasion, little ionizing radition, and mutli-planar imaging make the technique suitable for the patients requiring repeative medical check. However, the technique hasn’t been widely applied in gastrointestinal examination and evaluation. This article mainly makes a comparison between gastrointestinal examination and evaluation on the one hand, and focuses on the progress of gastric dynamics assessment with MRI technique.
