Ionization - any process by which a neutral atom gains or loses an electron, thus
acquiring a net charge
Magnetic Resonance Imaging - process of using a magnetic field and radiofrequencies
to create sectional images of the body
Mammography - radiography of the breast
Nuclear Medicine Technology - branch of radiology that involves the introduction of
radioactive substances into the body for both diagnostic and therapeutic purposes
Positron Emission Tomography - the creation of sectional images of the body that
demonstrate the psychologic function of various organs and systems
Radiation - energy transmitted by waves through space or matter
Radiation Therapy - branch of radiology involved in treatment of disease by means of x-
rays or radioactive substances
Radiography - making of records (radiographs) of internal structures o the body by
passing x-rays or gamma rays through the body to act on specially sensitized film or an
imaging plate or system
Radiologic Technologist - general term applied to an individual who performs
radiography, radiation therapy, or nuclear medicine technology
Radiologist - physician who specializes in the use of x-rays and other forms of both
ionizing and nonionizing radiation in the diagnosis and treatment of disease
Radiologist Assistant - an advanced-level radiographer who extends the capacity of the
radiologist in the diagnostic imaging environment, thereby enhancing patient care
Radiology - branch of health sciences dealing with radioactive substances and radiant
energy ans with the diagnosis and treatment of disease by means of both ionizing (ex:
roentgen rays) and nonionizing (ex: ultrasound) radiation
