Diagnostic Medical Sonography - Visualization of *deep structures* of the body by
*recording the reflections of pulses of ultrasonic waves* directed into the tissue.
Energy - Capacity to operate or work.
Ionization - Any process by which a *neutral atom gains or loses an electron*, thus
acquiring a net charge.
Magnetic Resonance Imaging (MRI) - Process of using a *magnetic field and
radiofrequencies to create sectional images* of the body.
Mammo*grpah*y - Radio*graph*y 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.

like, "Woah, are they gonna turn me into a radioactive ninja turtle in here!?")
Positron Emission Tomography (PET) - The creation of *sectional images* of the body
that demonstrate the *physiologic function* of various organs and systems.
Utilizes *radioisotopes*.
Radiation - *Energy transmitted by waves through space* or through a medium.
Radiation Therapy - Branch of radiology involved in the *treatment of disease* by
means of *x-rays* or *radioactive substances*.
Radiography - *Making of records* (radiographs) of internal structures of 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 (RT) - 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 (RA) - An *advanced-level radiographer who extends the capacity
of the radiologist* in the diagnostic imaging environment, thereby enhancing patient
care.
