title: Electrolytically labeled [99mTc]MDP: chromatographic pattern, stability and biodistribution in rats.
abstract: The labeling of methylene diphosphonate with 99mTc is possible after reduction of pertechnetate by means of controlled potential electrolysis. This results in a [99mTc]MDP complex which differs slightly from 99mTc(Sn)-MDP in paper and gel chromatography. The scintigraphic images of both preparations are comparable in quality. Biodistribution in rats shows a higher bone uptake for the 99mTc(Sn)-MDP complex, whereas [99mTc]MDP shows a higher uptake in the gastric wall.
