Isotope Bone Scanning

Description: Bone scanning uses a Technetium 99m diphosphonate or polyphosphonate. This becomes fixed to hydroxyapatite in the bone and marks those areas where bone is being laid down. The activity is high at any site where there is a bone reaction to any process or pathology. The diagnosis is made from a combination of pattern and clinical findings and by additional referral to the plain films.
