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 1.5T-MRI with navigation, the
gastric ulcer region was visualized in T1- and
T2-weighted images with sufficient SNR and CNR. These MR
images could correspond to a histological specimen of
ulcer region. Therefore, the feasibility of this system
was demonstrated.
