Bidentate monophosphates--phosphonoacetate (PAA), 2-phosphonoproprionate (PPA), 2-methyl-2-phosphonoproprionate (MPPA), and carbamyl phosphate (CAP)--which are pyrophosphate analogs, were successfully labeled with Sn(II)-reduced [99mTc] pertechnetate in high yield (greater than 95%). Biodistribution studies show that these Tc-99m-labeled monophosphates do localize in bone. At 2

The biologic and imaging characteristics of Tc-99m MDP and Tc-99m PPi were compared in animals and patients using freeze-dried bone-imaging kits. Biodistribution data in rabbits showed Tc-99m MDP had slightly higher bone uptake, significantly lower blood levels, and faster urinary
