bone densitometry (BD) - measurement of bone density using dual-energy x-ray absorptiometry (DEXA or DXA) to detect osteoporosis cardiovascular interventional technology (CVIT) - radiologic procedures for the diagnosis and treatment of diseases of the cardiovascular system computed tomography (CT) - recording f predetermined plane in the body using an x-ray beam that is measured, recorded, and then processed by a computer for display on a monitor 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 mammography - radiography of breast nuclear medicine technology - involves the introduction of radioactive substances into the body for both diagnostic and therapeutic purposes positron emission technology (PET) - the creating of sectional images of the body that demonstrate the physiologic function of various organs and systemsradiation - energy transmitted by waves through space or through a medium radiation therapy - involves treatment of disease by means of x-rays or radioactive substances radiography - making records 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 radiology - branch of health sciences dealing with radioactive substances and radiant energy and with diagnosis and treatment of disease by means of both ionizing and non ionizing radiation
