0 引言磁共振成像(MRI)是利用磁场中人体氢质子共振后产生的信号成像的方法,不同的脉冲序列可产生不同参数成像。在人体可任意层面成像,图像具有优秀的组织分辨率和空间分辨率,已成为中枢神经系统和肌骨组织最重要的检查方法之一。早期的磁共振机器扫描速度慢,成像序列少,胃肠道MRI检查主要限于食管和直肠的检查,随着MRI技术发展,如快速扫描、脂肪抑制技术和胃肠造影剂完善,MRI在胃肠道的应用已日趋广泛。
0 Introduction Magnetic resonance imaging (MRI) is the use of magnetic field generated by human proton resonance signal imaging method, different pulse sequences can produce different parameters of imaging. Imaging at any level of the human body, with excellent tissue and spatial resolution, has become one of the most important tests for the central nervous system and musculature. Early magnetic resonance machine scan slower, less imaging sequence, gastrointestinal MRI examination is mainly limited to esophageal and rectal examination, with the development of MRI technology, such as rapid scanning, fat suppression and gastrointestinal contrast agent perfect, MRI in gastrointestinal Road applications have become increasingly widespread.
