[Kinetic study of indium-111 labelled platelets in idiopathic thrombocytopenic purpura (author's transl)].

Labelling platelets with 111 Indium-oxine has advantages over the conventional 51 Chromium method: labelling is more efficient and the radiations emitted almost exclusively consist of gamma-rays. Owing to these advantages, autologous platelets can be used for kinetic studies in patients with idiopathic thrombocytopenic purpura, even when thrombocytopenia is severe. 111 Indium labelling also provides accurate information on the sites of platelet destruction, which may help to predict the patient's response to splenectomy.
