ect in the bones of the skeleton of inflammatory or infectious processes, the doctor may perform a few shots to track the dynamics of the process immediately after the introduction of a radioactive pharmaceutical preparation.To contrast agent does not remain in the internal organs, the day before scanning the patient is recommended to drink plenty of fluids, and immediately prior to the diagnosis you need to empty the bladder.After a bone scan should continue to use as much liquid as possible (within two days), to bring the body of residues of radioactive drug.
