The last decade has seen significant increases in the amount of diagnostic radiation to which patients with GI disorders attending specialist centers are exposed. The majority of this exposure is due to abdominal CT. Higher levels of exposure are more likely in patients with IBD and organic small bowel disorders but are also associated with other organic and functional diagnoses. Given the likely deleterious effects of exposure to ionizing radiation and the age and gender profile of patients in these disease categories, there is a clear need for evidence-based guidelines on the use of diagnostic imaging in patients with organic and functional GI disorders.
