    Abstract:
    Fifty-two patients suspected of having deep vein thrombosis under-went scintigraphy with an indium-111-labeled monoclonal antifibrin antibody. Venography disclosed deep vein thrombosis in 31 patients. With the whole limb considered an anatomic entity, antifibrin antibody scintigrams obtained 2 hours after injection had a specificity and sensitivity of 81% and 84%, respectively. A higher sensitivity (92%) was found for a subgroup of patients (n = 44) with symptoms for less than 10 days. Regional sensitivities for all patients and for the subgroup, respectively, were 92% and 100% in the calf, 82% and 94% in the popliteal region, 63% and 71% in the thigh, and only 18% and 13% in the pelvis. Additional imaging performed 6 hours and 21 hours after injection in 12 patients and quantitative analysis done from scintigrams with and without blood-pool (technetium-99m human serum albumin) correction did not improve sensitivity. In-111-antifibrin antibody scintigraphy is an accurate method for diagnosis of acute established deep vein thrombosis of the calf and popliteal region; its sensitivity in the thigh is lower, and it is not feasible for diagnosis in the pelvic area.
