Multidetector row CT of small bowel tumours.

Computed tomography is being increasingly used for the evaluation of patients with vague abdominal symptoms, and may provide the initial opportunity to detect and characterize tumours of the small bowel. The recognition of imaging features on CT allows distinction to be made between benign and malignant neoplasms. Multidetector row CT (MDCT) provides high-resolution imaging and helps in precise localization and characterization of lesions. This article illustrates the imaging appearances of small bowel tumours on MDCT and demonstrates the usefulness of multiplanar reformatting (MPR) in the diagnosis and categorization of these tumours.
