Detection of aneurysms by gamma-camera imaging after injection of autologous labelled platelets

Autologous platelet labelling was used to calculate platelet half-life in 860 patients with symptoms of coronary heart disease and/or peripheral vascular disease. Abnormal platelet deposition indicating an abdominal aortic aneurysm was found in 21 by gamma-camera imaging after reinjection of autologous indium-111 labelled platelets. Aneurysms detected by imaging were confirmed by angiography, computer tomography, and at subsequent surgery.
