In cases with negative endoscopic findings and high clinical suspicion, selective angiography of the mesenteric arteries is sometimes necessary. An alternative is scintigraphy with red blood cells labeled with technetium-99m, a radioactive marker; this shows the site of the bleeding on a gamma camera but unhelpful unless the bleeding is continuous and significant.[1] Another drawback is the lack of specificity of localisation of the bleeding site.[2]
