CT is useful for the evaluation of adhesive small bowel obstruction, to detect accurately patients with complications who require urgent operation and to determine the location of the adhesion, which represents a significant prognostic factor for success of conservative treatment.

The use of fine needle aspiration biopsy, interpreted by an experienced cytologist, means that short term follow-up of fibroadenomas can be avoided.
