the study of the uses of radioactive substances for visualizing the internal structures of the body in order
to diagnose and treat disease. it is divided into three specialties: diagnostic radiology, radiation therapy,
and nuclear medicine - Correct Answers radiology
an electromagnetic wave with a high energy level and short wavelength that can penetrate solid objects.
X-rays can be used in diagnosis and therapy. - Correct Answers X-Ray
a form of X-ray imaging in which digital X-ray sensors are used instead of traditional photographic film.
they reduce processing time and also require less radiation to produce images - Correct Answers digital
x-ray
the ability of certain materials to attract iron and other metals - Correct Answers magnetism
capable off emitting radiant energy; or giving off radiation as the result of the disintegration of the
nucleus of an atom. - Correct Answers radioactive
energy produced by fission of an atomic nucleus - Correct Answers nuclear energy
refers to something that does not permit the passage of X-rays. Bones are relatively radiopaque. -
Correct Answers radiopaque
radiopaque substances used in radiography to permit visualization of internal structures. contrast
visualization include liquids, powders, and gases. They are administered orally, parenterally, and
rectally. A positive contrast medium is more dense than the surrounding tissue. a negative contrast
medium is less dense than the surrounding area in the body. barium sulfate and iodine are positive
contrast media. air is a negative contrast media. - Correct Answers contrast media
oral agents may cause skin rash, vomiting, diarrhea, abdominal pain, or constipation. IV agents can
cause urticaria (rash), skin reddening, anaphylaxis, or death. some individuals have allergies to iodine. -
Correct Answers adverse effects of contrast media
, a special material with a sensitive emulsion layer that reacts when it is exposed to radiation and thereby
produces an image. Single-emulsion film is used to create images of the extremities and the breasts. -
Correct Answers x-ray film
an image recorded on film that has been exposed. An older term for radiograph is roentgenogram,
named after the discoverer of X-rays, Wilhelm conrad roentgen. - Correct Answers radiograph
an unwated increase in the density of the emulsion either before or after exposure to radiation. heat,
light, chemicals, and extraneous radiation can produce fogging which appears as darkened areas on the
finished radiograph - Correct Answers film fog
extraneous marks and areas of increased or decreased density on film. artifacts interfere with diagnostic
value of the radiograph - Correct Answers artifacts
a light-proof container that holds X-ray film and serves to intensify the image - Correct Answers cassette
the visible difference between any two areas of radiographic density - Correct Answers contrast
a unit used to measure X-ray dosage in air - Correct Answers roentgen
a unit used to measure the X-ray dosage in human beings. it is abbreviation of roentgen equivalent in
man. - Correct Answers rem
a unit used to measure the actual absorbed dose of radiation - Correct Answers rad
the process by which an atom becomes ionized (gains or loses electrons) - Correct Answers ionization
radiation that causes ionization in the tissues that absorb it. - Correct Answers ionizing radiation
an image produced on film by a sweeping beam of radiation - Correct Answers scan
