[Comparative analysis of MDP bone imaging agents used in Taiwan]

Bone scans have been established as a major investigative procedure for various bone, muscle and joint diseases, and for the detection of bony metastases. MDP (methylene diphosphate) labeled with Tc-99m is currently used for bone imaging. The quality of bone imaging agents can affect the quality of the bone image. In this work we compared the quality control for three commercially available MDP kits (Daiichi, Amersham, NEN) in Taiwan, and the imaging quality among the various MDP kits. Our results revealed a slight difference of quality control in various brands of Tc-99m MDP. However, there was no significant difference in the imaging quality among the various MDP kits.
