The Effect of Tin on the Tissue Distribution of99mTc-Sodium Pertechnetate

Abstract
When tin complex was administered prior to the injection of 99mTc-sodium pertechnetate [into humans], the distribution of the tracer was altered. The concentration at foci of cerebral pathology was drastically reduced; the concentration in the stomach (mucus cells), thyroid and salivary glands and choroid plexus was greatly increased and there was a shift of the tracer from the plasma to the red blood cells. Bone studies utilizing a tin complex should be done after other organs have been evaluated.
