Otomi Y, et al. - Researchers retrospectively estimated the capabilities of SPECT/CT in the diagnosis of gastrointestinal bleeding by a comparison with planar imaging alone as well as planar and SPECT. They retrospectively analyzed 20 patients (21 examinations) who underwent gastrointestinal bleeding scintigraphy in the past 7 years and in whom the bleeding site was identified by endoscopy or capsule endoscopy, or in whom no evidence of gastrointestinal bleeding was identified during the clinical course. As per outcomes, the 3 imaging methods detected the presence of gastrointestinal bleeding with good accuracy. The addition of SPECT or SPECT/CT helped providing clarity about the anatomical position of the uptake and contributed to the localization of the site of gastrointestinal bleeding. Hence for detecting the site of gastrointestinal bleeding, planar + SPECT/CT imaging was supported to have the highest diagnostic ability.
