title: Technetium-99m red blood cell venography of the lower limb in symptomatic pulmonary embolization.
abstract: Tc-99m RBC venography of the legs was obtained in 42 patients with primary pulmonary symptomatology and a diagnosis of pulmonary embolization. In 31 of these 42 patients (74%), the nuclear venogram revealed the presence of deep vein thrombosis (DVT) and a source of embolization. Of the 31 patients with leg DVT documented by venography, 13 (42%) showed thrombosis confined to the calf. Clinical findings suggested that only 20 of the 31 patients (65%) with DVT could have harboured a source of embolization in the legs. Tc-99m RBC venography is a useful noninvasive test for the global and comprehensive assessment of patients with symptomatic pulmonary embolization.
