The development of a new treatment-support system combined endoscopy with magnetic resonance imaging(MRI)

本研究的目的是开发一种新的治疗支持系统结合内窥镜与磁共振成像（MRI）。使用紧密放置在胃肠道壁的表面线圈的腔内MR成像能够以与EUS成像相似的质量可视化活体猪胃肠道壁层的分化。此外，可以观察粘膜下层的血管结构。磁共振腔内成像不仅有助于胃肠道病变的诊断，而且有助于安全的内镜治疗。

The purpose of this study is to develop a new treatment-support system combined endoscopy with magnetic resonance imaging (MRI). Endoluminal MR imaging using the surface coil closely placed to the gastrointestinal wall was able to visualize the differentiation of living porcine gastrointestinal wall layers with similar quality to EUS imaging. Additionally, it was possible to visualize the vascular structures in the submucosal layer. Endoluminal MR imaging would be useful not only for diagnosis of the gastrointestinal lesion but also for safely endoscopic treatment.
