RADIOLOGY
The branch of medicine that deals with the use of radioactive substances in diagnosis and treatment of disease.
Branch of medicine that uses radiation for diagnosis (diagnostic imaging) and treatment (radiation therapy) of disease. Originally, it involved X rays for diagnosis and X rays, gamma rays, and other ionizing radiation for treatment. Diagnostic methods now include isotope scanning ( nuclear medicine), use of nonionizing radiation, as in ultrasound
and magnetic resonance imaging, and radioimmunoassay (in which
radioactive isotopes in antibodies against hormones detect minute
amounts of hormones for diagnosis of endocrine disorders). Radiotherapy
now includes, in cancer treatment, radioactive hormones and
chemotherapeutic drugs.
