| Abstract: | When tin complex is administered prior to the injection of 99mTc-sodium pertechnetate, the distribution of the tracer is altered such that: (a) the concentration at foci of cerebral pathology is drastically reduced; (b) the concentration in the stomach (mucus cells), thyroid and salivary glands, and choroid plexus is greatly increased; and (c) there is 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. |
