An integrated MR-endoscope system that provides high quality MR images with an
endoscopic view and information of the scope location has been developed to improve the
accuracy and safety of endoscopy and endoscopic surgeries. To examine the feasibility of
this system, the MR imaging of a gastric ulcer in animal experiments was conducted in vivo.
Using an intra-cavitary RF coil for 1.5 T-MRI with navigation, the gastric ulcer region was
visualized in T1-and T2-weighted images with sufficient SNR and CNR. These MR images …
