How do diagnostic radiography, radiation therapy and nuclear medicine differ?
A doctor has provided 1 answer
Different radiation: Radiography or x-ray involves low dose ionizing radiation with images of chest , skeleton, skull etc. Radiation therapy uses high dose ionizing to treat tumors with external or internal irradiation. Nuclear medicine involves low dose ionizing radiation in form of isotopes that are internally injected intravenously. Inhaled, injected subcutaneously, or ingested orally.
