Emission / transmiss: A bone scan images bone physiology... How the bone is metabolizing calcium. An x-ray looks at the anatomy of the bone. A bone scan is an emission scan and x-ray a transmission scan. A bone scan is a nuclear medicine procedure, and an x-ray a radiology procedure.

Both radiation: Nuclear medicine radiation is given internally via IV injection, ingestion, or inhalation for determination of function of organs of body. Isotopes have different half lives and decay at different rates.Ct/xray is external radiation for visualization of anatiomy and pathology. Both contribute to radiation dose. Both are ionizing radiation. Ultrasound and MRI do not involve irradiation.
