Scintigraphic localization of intermittent gastrointestinal haemorrhage with indium-111-labelled platelets.
Because of the central role of blood platelets in haemostasis, 111In-labelled platelets might be supposed to participate in the haemostatic process and give rise to scintigraphic hot spots at the bleeding sites in cases of intermittent gastrointestinal haemorrhage. Three patients with intermittent gastrointestinal haemorrhage are described in whom focal tracer accumulations after injection of autologous 111In-labelled platelets indicated the presence of transient gastrointestinal haemorrhage. Repeatedly performed scintigraphy after injection of 111In-labelled platelets may prove to be a useful tool for the localization of intermittent gastrointestinal haemorrhage.
