title: Labeling efficiency and stomach concentration in methylene diphosphonate bone imaging.
abstract: When Tc-99m-labeled methylene diphosphonate was used 4.75 hr after reconstitution, stomach concentration was seen in the majority of patients. The number of patients with stomach concentration increases with time and is associated with the increasing amount of product breakdown. The reconstituted labeled MDP should not be used after 4-5 hr if stomach concentration is to be avoided.
