(Computed Tomography) Technologist
specialize in computed tomography (CT), and are sometimes referred to as
CT technologists. CT scans produce a substantial amount of
cross-sectional x-rays of an area of the body. From those
cross-sectional x-rays, a three-dimensional image is made. The CT uses
ionizing radiation; therefore, it requires the same precautionary
measures that radiographers use with other x-rays.
(Magnetic Resonance) Technologist
Radiographers also can
specialize in Magnetic Resonance Imaging (MR) as an MR technologist. MR, like
CT, produces multiple cross-sectional images to create a 3-dimensional
image. Unlike CT, MR uses non-ionizing radio frequency to generate image
In addition to radiologic
technologists, others who conduct diagnostic imaging procedures include
cardiovascular technologists and
medical sonographers, and
nuclear medicine technologists.
specialty for radiographers specialize in is mammography. Mammographers
use low dose x-ray systems to produce images of the breast.
