ra·di·ol·o·gy (rd-l-j)

n.

1. The branch of medicine that makes diagnostic images of anatomic structures through the use of electromagnetic radiation or sound waves and that treats disease through the use of radioactive compounds. Radiological imaging techniques include x-rays, CAT scans, PET scans, MRIs, and ultrasonograms.

2. The use of radiation for the scientific examination of material structures; radioscopy.

radiology

[-ol′əjē]

Etymology: L, radius + logos, science

the branch of medicine concerned with radioactive substances and with the diagnosis and treatment of disease by visualizing any of the various sources of radiant energy. Three subbranches of radiology are diagnostic radiology, imaging using external sources of radiation; nuclear medicine, imaging radioactive materials that are placed into body organs; and therapeutic radiology, the treatment of cancer using radiation. Formerly called roentgenology. radiologic, radiological, adj.

radiology, oral,

n all phases of the science and art of radiology that are of interest to the dental profession. Oral radiology involves the generation and application of roentgen rays for the purpose of recording shadow images of teeth and their supporting tissues, adjacent regions, and associated parts. It also includes the interpretation of the radiographic findings.
