The project to develop an integrated MR-endoscope system to help an endoscopy and an endoscopic surgery is ongoing. This study is one of this project, and the purpose of this study is to create an MR probe (RF coil) to insert into gastrointestinal tract through the mouth and to obtain a high spatial resolution MR images of gastric and esophageal wall. Making a flexible structure RF coil, the coil could be inserted into gastrointestinal tract easily, and the high spatial resolution MR images of gastric and esophageal wall of pig were successfully obtained and each layer in them was identified. In addition, blood vessels in gastric wall were visualized.
