The results of a bone scan are usually available within 2 days.
The radioactive tracer is evenly spread among the bones. No areas of too much or too little tracer are seen.
The tracer has accumulated in certain areas of the bone, indicating one or more "hot" spots. Hot spots may be caused by a fracture that is healing, bone cancer, a bone infection (Reference osteomyelitis Opens New Window), Reference arthritis Opens New Window, or a disease of abnormal bone Reference metabolism Opens New Window (such as Reference Paget's disease Opens New Window).
Certain areas of the bone lack the presence of tracer, indicating one or more "cold" spots. Cold spots may be caused by a certain type of cancer (such as Reference multiple myeloma Opens New Window) or lack of blood supply to the bone (bone infarction).
