Crohn's disease of the small intestine: a comparative study of the radiological and pathological appearances.

A prospective study was carried out to compare the radiological and pathological appearances of Crohn's disease of the small intestine. The X-ray examinations were carried out by infusing barium directly into the small intestine. Thirty-six patients who were operated on for Crohn's disease of the small intestine are included. There was excellent correlation between the radiological appearances and the findings at morbid anatomy.
