Functional abnormalities of the gastrointestinal tract in patients with spinal cord injuries: evaluation with imaging procedures.

One quarter of patients with spinal cord injuries eventually have severe chronic gastrointestinal symptoms. Because there are about 1.5 million such patients in the United States, major chronic gastrointestinal symptoms will develop in approximately 400,000 patients, all of whom are likely to need the services of radiologists. These gastrointestinal abnormalities, however, are quite different from the gastrointestinal problems that occur in the general population. For this reason, the imaging methods used for diagnosis in these patients are also different from those used with persons who do not have spinal cord injuries. The purpose of this review is to describe the role of diagnostic imaging in patients with severe chronic gastrointestinal symptoms associated with spinal cord injury.
