Expectoration in the Gastrointestinal Tract A Diagnostic Problem in ln-111 Granulocyte Scintigraphy

摘要

Scintigraphic detection of infectious foci with ln-111 labeled granulocytes or leukocytes is a well-established technique in nuclear medicine. The technique is commonly used to demonstrate inflammatory activity in Crohn's disease and ulcerative colitis. Its application, however, may be influenced by infectious expectoration located within the gastrointestinal tract. In performing this technique, it is important to have this differential diagnostic possibility in mind; it can be clarified by repeated imaging.
