Whole-body bone scanning involves injecting radioactive isotopes into the bloodstream. The isotopes are slightly radioactive and are associated with bone metabolism and blood circulation, and once bone damage occurs, there will be an aggregation of radioactive isotope concentrations at the place of damage. Usually used to observe whether there is bone damage and lesion sites, the radiation of this substance is very weak, the impact on the human body is very small, the metabolism of this radioactive material is also very fast, about three hours after the injection, through the urine can be discharged 60% of the whole body bone scan is safe. It should be noted that after the bone scan, within two days there is still part of the radioactive drug residue, and then avoid contact with infants, pregnant women within two days after the examination, avoid staying in densely populated public places, it is recommended to drink more water, eat more vegetables, eat more bananas, do not eat greasy food.
