GREY-SCALE ULTRASOUND IN CROHN DISEASE

Grey scale ultrasound examination was performed in 20 patients with Crohn's disease of varying extent and severity. In 15 of the 20 patients studied, thickening of the wall of the terminal ileum and caecum, with adjoining inflammatory changes in the mesentery, produced recognisable patterns on longitudinal and transverse ultrasonographs. Grey scale ultrasound, although not providing the specificity or detail of conventional radiology, can be helpful in the assessment of ileocaecal Crohn's disease, particularly in younger patients where the radiation hazards of repeated x-ray examinations are undesirable.
