[Effect of Residual Volume in a Three-way Stopper and a Syringe on Actual Dose of Radiopharmaceuticals: Effect of Different Three-way Stoppers and Washing].

The purpose of this study were to evaluate the residual volume of radiopharmaceuticals in the three-way stopper and syringe used during radiopharmaceutical administration and the effect of washing. The three-way stoppers were a top injector tube, a top three-way stopper, and a Nipro three-way stopper with a needle. Sodium pertechnetate [Tc] injection (TcO) was used to compare the residual volume of radiopharmaceuticals in the three-way stopper and syringe without and with washing.
