Technetium labelled red blood cell scintigraphy in the diagnosis of intestinal haemorrhage
99m-Technetium labelled red blood cell scintigraphy was used in the investigation of 15 adult patients with suspected small or large bowel bleeding requiring at least five units of blood (mean 14.3 units) and one neonate with rectal bleeding. Scintigraphy was found to be an accurate method of detecting the site of haemorrhage and was superior to angiography. This technique may be of particular value in patients with profuse colonic haemorrhage when the view at colonoscopy is poor.
