Radiology Modalities Flashcards
MRI
Magnetic Resonance Imaging is a diagnostic
procedure that uses a combination of a large magnet, radiofrequencies, and a
computer to produce detailed images of organs and structures within the body. Cross
sectional views can be obtained to reveal details. MRI does not use radiation, as do x
rays or CT scans. Education: Need to be a certified technologist.

Magnetic Resonance Imaging (MRI)
Computerized Tomography (CT)
does not use radiation, as do x
rays or CT scans.
Magnetic Resonance Imaging (MRI)
What does CT stand for?
Computerized Tomography
a diagnostic imaging
procedure that uses a combination of x-rays and computer technology to produce
cross-sectional images (often called “slices”), both horizontally and vertically, of the
body.
Computerized Tomography (CT)
A _________ scan demonstrates detailed images of any part of the body, including the
bones, muscles, fat, and organs.
Computerized Tomography (CT)
_________ scans are more detailed than general x-rays.
Computerized Tomography (CT)
an x-ray examination of the breast
mammogram
Used to detect and diagnose breast disease in women (and men) who either have breast problems such as a lump, pain, or nipple discharge, as well as for women (or men) who have no breast complaints.
mammogram
use invisible electromagnetic energy beams to
produce images of internal tissues, bones and organs on film.
diagnostic x-rays
a specialized area of radiology that uses very
small amounts of radioactive materials, or radiopharmaceuticals, to examine organ
function and structure.
Nuclear Medicine
a combination of many different
disciplines, including chemistry, physics, mathematics, computer technology, and
medicine. This branch of radiology is often used to help diagnose and treat
abnormalities very early in the progression of a disease, such as thyroid cancer.
Nuclear medicine
uses high-frequency sound
waves and a computer to create images of blood vessels, tissues, and organs.
Ultrasonography
also called sonography
Ultrasonography
Used to view internal organs and to assess blood flow through
various vessels.
Ultrasonography
Often used to examine many parts of the body such as the abdomen, breasts, female pelvis, prostate, scrotum, thyroid and
parathyroid, and the vascular system.
Ultrasounds
During pregnancy, these are performed
to evaluate the development of the fetus.
Ultrasounds
the treatment of
cancer and other diseases with radiation.
Radiation Therapy
High energy x-rays are used to kill the
cancer cells by preventing them from multiplying.
radiation therapy
used to cure or control cancer, or to alleviate some of the symptoms associated with cancer.
radiation therapy
x-ray images of blood vessels in the body
angiograms
the x-ray images allow a doctor to determine whether a blood vessel is
blocked, constricted, malformed, or otherwise obstructed or damaged.
angiograms
What does the abbreviation PET mean?
Positron Emission Tomography
a nuclear medicine functional imaging technique that is used to observe metabolic processes in the body as an aid to the diagnosis of disease.
PET Positron Emission Tomography
This exam is a combination of nuclear medicine and CT imaging.
Positron Emission Tomography
The system detects radioactive isotopes, which is introduced into the body. In modern scanners, three-dimensional imaging is often accomplished
with the aid of a computed tomography X-ray scan performed on the patient during the
same session, in the same machine.
