[Detection of arterial thrombi using blood platelets labeled with indium-111]

Scintigraphy with Indium 111-labelled platelets was carried out in 62 patients (37 transient cerebral ischaemic accidents, 21 lower limb ischaemic episodes and 4 aortic aneurysms) to detect arterial thrombi. The results of this investigation were compared with the surgical findings and showed this to be a satisfactory method of detecting haematologically active thrombi.
