[ Summary ] |
We have performed endoscopic MR (endo-MR) for the diagnosis of gastrointestinal tumors. Since 1995, we have used a MR-endoscope (XGIF-MR 30) with a small Radio-Frequency coil mounted in its tip. The MR endoscope was inserted into the duodenum, the patient was placed in a prone position in an MRI scanner. The pulse sequences used for this method were of the fast SPGR type. After the normal scan, six axial scans were performed, after intravenous injection of 20ml of Gadlinium-DTPA. Pancreatic tumors were detected more frequently by use of endo-MR (87.5%) than by computed tomography (CT). The accuracy of endo-MR diagnosis of cancer extension in patients with carcinoma of the head of the pancreas was the same as that obtained by use of CT and endosonography (EUS); TS factor 100%, S factor 75%, RP factor 100%, and PV factor 75%. Endo-MR is a useful method for diagnosing pancreatoduodenal tumors. |
