MR endoscopy: preliminary experience in human trials.

The authors performed local staging of esophageal and rectal cancer (without pathologic correlation) with use of a nonferromagnetic magnetic resonance (MR) endoscope with a 3-cm-long receive-only coil embedded in its tip in 16 patients (eight with esophageal cancer and eight with anorectal cancer). Results with spin-echo sequences were optimal in all cases [corrected].
