Physiologic imaging: Nuclear scans involve ingestion, intravenous injection, inhalation, subcutaneous injection , instillation into bladder of isotopes, radiotracers, in order to see function of various organs of body, heart, lungs, bones, liver/spleen, stomach, thyroid, lymph system, kidneys, bladder, brain, parathyroid gland and gall bladder.Normal values for adults and children are known.Radiation involved.
