Radiolabelled anti-human fibrin antibody: a new thrombus-detecting agent.
Rabbit anti-human fibrin globulin (A.F.G.) was labelled with iodine (131I) and used as a thrombus-detecting agent. 131I-A.F.G. labelled thrombi were displayed by means of a gamma scintillation camera. Normal subjects and patients with thrombophlebitis of legs, acute fibrin depositions other than thrombi, and chronic varicosities were examined. The 131I-A.F.G. technique detected both formed thrombi and those that were forming and could discriminate between acute thrombosis and chronic varicosities. Thrombophlebitis and extravascular fibrin depositions were best demonstrated between 24 and 27 hours of 131I-A.F.G. injection. Radiolabelled A.F.G. in normal veins and chronic varicosities was best displayed within 6 hours of injection.
