Radiopharmaceuticals are the preferred agents for the assessment of function, as opposed to structure. Renal imaging agents are classic examples in that sense, since they allow the monitoring of the imaging of glomerular filtration and tubular secretion functions of the kidneys. Currently there are two agents available one is Tc-DTPA of unknown structure, and the other one is the... 

Until recently it has rarely been possible to definitively characterize the "mTc species present in a radiopharmaceutical formulation because of the extremely low concentrations involved. In some cases, electrophoresis has been used as a means of determining the minimum number of species present. In a recent example a methylene diphosphonate formulation for preparing a "mTc bone imaging agent was found to produce at least four different "mTc species.581 In favourable circumstances it may be possible to determine the net charge on the ionic materials present by this technique. However, such measurements require careful interpretation if erroneous conclusions are to be avoided, and they provide no detailed information relating to chemical structure.20...
