Indium-111 labelled platelets in diagnosis of leg-vein thrombosis: preliminary findings.

Abstract

Platelets from eight patients thought clinically to have deep venous thrombosis were labbelled with indium-111 and reinjected. Subsequent scanning of the patients with a wholebody scanner and imaging with a gammacamera showed focal accumulation of the label at five sites in four legs, which correlated precisely with the sites of venous thrombi identified by ascending venography. This technique is a useful addition to methods for diagnosis venous thrombosis.
