Likewise, the use of CTA as the first test leads to faster triage of patients in the emergency room when compared with endoscopy for GI bleed [24]. Nonvariceal Upper Gastrointestinal Bleeding CTA Abdomen With IV Contrast Although CTA can detect GIB, typically both the abdomen and pelvis are imaged, because the site of bleeding is unclear without endoscopy. There is no significant literature supporting the use of CTA abdomen with IV contrast only. CTA Abdomen Without and With IV Contrast Although CTA can detect GIB, typically both the abdomen and pelvis are imaged, because the site of bleeding is unclear without endoscopy. There is no significant literature supporting the use of CTA abdomen without and with IV contrast only. CTA Chest With IV Contrast Although esophageal bleed (which can be localized on CTA chest) can present as UGIB, the literature supports CTA of abdomen and pelvis if the site of bleeding is unclear without endoscopy. There is no significant literature supporting the use of CTA chest with IV contrast. CTA Chest Without and With IV Contrast Although esophageal bleed (which can be localized to CTA chest) can present as UGIB, the literature supports CTA of abdomen and pelvis without and with IV contrast, if the site of bleeding is unclear without endoscopy. There is no significant literature supporting the use of CTA chest without and with IV contrast. Fluoroscopy Upper GI Series Barium or iodine upper GI series has no role in the diagnosis of acute UGIB in a modern-day practice. MR Enterography There is no significant literature supporting the use of MR enterography in patients with overt UGIB. RBC Scan Abdomen and Pelvis There is no significant literature to support the use of a Tc-99m-labeled RBC scan of the abdomen and pelvis for the initial imaging of suspected overt UGIB (without endoscopy performed). Variant 2: Adult.
