title: [The hydro-MRT of chronic inflammatory bowel diseases].
abstract: OBJECTIVE
  Evaluation of hydro-MRI in the diagnosis of chronic inflammatory bowel disease (IBD).
  
  
  METHODS
  33 patients with suspected Crohn's disease or ulcerative colitis were studied prospectively. After distension of the colon by a rectal enema, breathhold MR imaging was performed during bowel relaxation. Results were compared to the clinical diagnosis, endoscopy, barium studies and histopathology.
  
  
  RESULTS
  24/24 patients with active Crohn's disease were correctly diagnosed by MRI. Conversely, MRI was positive in only 2/5 patients with ulcerative colitis. In 5 patients the presence of IBD was excluded. There were no false positives.
  
  
  CONCLUSIONS
  Hydro-MRI is a very reliable modality in the diagnosis of Crohn's disease. In the differentiation of Crohn's disease from ulcerative colitis, hydro-MRI seems to be a promising imaging procedure.
