- “Although CT enterography has limited sensitivity (55.2%; 16 of 29 patients) in identifying the source of obscure gastrointestinal bleeding, positive CT enterography findings can reliably indicate the true cause of of obscure GI bleeding with a high positive predictive value (100%; 16 of 16 patients).”

Radiology 2011; 259:739-748 - “ CT enterography has a potential role in the evaluation of obscure gastrointestinal bleeding. Despite the limited sensitivity of CT enterography, positive CT enterographic findings can reliably indicate the true source of obscure gastrointestinal bleeding. CT enterography is particularly effective in helping identify the source of bleeding in patients with a history of massive bleeding.”
