title: Scintigraphic diagnosis of protein losing enteropathy using Tc-99m dextran.
abstract: The authors performed abdominal scintigraphy using intravenously administered Tc-99m dextran in a patient with protein losing enteropathy. The study revealed abnormal leakage of the radiotracer in the left lumber area that moved over time in a pattern suggestive of small intestinal transit. Besides being a nonprotein and having long stay in intravascular compartment, the macromolecule may have many advantages over Tc-99m human serum albumin, the current radiotracer of choice for imaging intestinal protein loss.
