Background and Aim: The purpose of this study was to investigate the diagnostic value of magnetic enteroclysis (ME) in comparison with three established techniques for the study of the small bowel, namely: Computed tomography of abdomen (CTS), Transdermal abdominal ultrasound (TUS) and small bowel follow-through (SBFT).

Patients and Methods: Twenty-four consecutive patients with Crohn's disease were submitted to ME. The findings from the mucosa, the intestinal wall and the adjacent tissues were compared with those of conventional CTS, TUS and SBFT.

Results: ME and SBFT detected the number, length and location of the affected part of the small bowel at rates that did not differ significantly. The detection of stenotic areas was unsatisfactory with TUS, although the exact thickness of the intestinal wall in the affected areas was satisfactorily demonstrated. CTS did not differ significantly from the TUS, although it its sensitivity was inferior compared to ME. ME detected abnormalities such as ulcers and mucosal thickening at rates no more than 50% but its sensitivity to demonstrate prestenotic dilatation of the bowel was 100%. The presence of mesenteric lymphadenitis did not differ significantly between ME, TUS and CTS.

Conclusion: In patients with small bowel Crohn's disease, ME seems to be an important method for the precise detection of the affected areas at higher rates compared to CTS and TUS. In the near future ME will probably become the most important method for the study of patients with small bowel Crohn's disease.
