Evaluation of radiochemical purities of routinely used radiopharmaceuticals: Three years’ experience of a single institute
Introduction: Radiochemical purity (RCP) is a routine quality control test carried out at nuclear medicine to determine the concentration of various chemical species present in the radiopharmaceuticals (RPs). The present work describes three years of experience in a single institute for the measurement of these impurities in the RPs preparations. Methods: </strong...
متن کاملQuantification of oestrogen receptors in breast cancer: radiochemical assay on cytosols and cryostat sections compared with semiquantitative immunocytochemical analysis.
A radiochemical oestrogen receptor assay on cytosol was correlated with a radiochemical and an immunohistochemical oestrogen receptor assay using cryostat sections from 50 breast cancer specimens. Oestrogen receptors were reliably quantitated in 6 micron cryostat sections with Scatchard analysis using radiolabelled oestradiol, and a good quantitative and qualitative relation with cytosol oestro...
متن کاملRapid miniaturized chromatography for technetium-99m-tetrofosmin.
UNLABELLED The purpose of this investigation was to develop and evaluate a new and rapid miniaturized chromatography system that would accurately assess the radiochemical purity of 99mTc-tetrofosmin without the problems of solvent ratios and time requirements associated with the manufacturer's recommended procedure. METHODS The migration of the radiochemical components of 99mTc-tetrofosmin wa...

متن کاملTrace Characterization of Refractory Metals by Activation Techniques
The application of activation techniques to the assay of the refractory metals niobium, molybdenum, tantalum and tunjsten for their trace element impurities is reviewed. Activation with reactor neutrons, fast neutrons, charged partides and photons in connection with both the non-destructive and the radiochemical performance is considered. The decisive contribution of activation techniques to th...
