Abstract
AIM: To explore the value of rectal magnetic resonance hydrography (MRH) in rectal carcinoma.
METHODS: Thirty-four patients with rectal carcinoma were included in the study. All underwent plain scan, three-planar enhanced scan and hydrography.
RESULTS: All foci were correctly detected by rectal MRH, which showed that there were irregular intraluminal filling defects (n = 32), and that “cuff” or “sawn-off” signs were seen at the distal end of the tumor (n = 19). Main MRH findings were: intraluminal soft tissue mass (n = 30), irregular thickening of the rectal wall and partial or circumferential stenosis of the rectal lumen (n = 26). The accuracy of rectal MRH for T staging was 82 ......
