No iodine bone scan: Nuclear medicine bone scans are performed using a radionuclide called tc 99m mdp. It is a radioactive particle tagged to a molecule involved in bone metabolism. Common exam, around for decades. There is now a new scan using a pet/ct scanner and an isotope sodium flouride. It is sensitive and more accruate but also more expensive and less available.

These are different: A radionuclide bone scan is performed with 99mtc-mdp and is used to detect bone infection, trauma, metastases, inflammation etc. Radioactive iodine will not detect bone disease unless there are bone metastases from a primary cancer of the thyroid gland. Bone scan is very sensitive for detection of various disease while whole-body iodine scan is very useful to detect metastases from thyroid cancer.
