title: Pulmonary arteriovenous malformation: radionuclide detection and quantification of right-to-left shunting.
abstract: Radionuclide detection and quantification of right-to-left shunting in two patients with pulmonary arteriovenous malformation and Rendu-Osler-Weber disease are described. Radionuclide studies are simple, atraumatic, and clinically useful in determining the vascular nature of the lesion and in quantifying the amount of right-to-left shunting with reasonable accuracy both before and after operation.
