Abstract
The quality of intravenous bolus injections of technetium-99m (99mTc)-labeled methylene diphosphonate (MDP) was compared between the bolus syringe* and a currently used method of bolus administration† in 13 patients undergoing routine bone scanning. No significant difference was found between the quality of the bolus injections using the two systems. However, the bolus syringe is more convenient to use and costs half the price.
