RADT60 Midterm Questions and Correct
Answers
Electrocardiography Ans: (ECG, EKG) - A graphic record produced
by an electrocardiograph, a device for recording heart rhythm by
measuring electrical conduction through the heart
Radiography Ans: Uses electromagnetic energy in the form of x-
rays to create medical images.
Sonography Ans: Uses high-frequency sound energy to create
medical images.
Nonionizing
Magnetic resonance imaging Ans: (MRI) - Uses the energy of high-
strength magnetic fields and radio waves.
-Nonionizing
Thermography Ans: The body's naturally emitted heat energy can
produce images for diagnostic purposes

Mammography Ans: Specific type of breast imaging that uses low-
dose x-rays to detect cancer early (before women experience
symptoms, when it is most treatable.)
It can help reduce the number of deaths from breast cancer among
women ages 40 to 70.
Myelography Ans: A fluoroscopic examination of the spine after
the injection of a radiopaque medium
Arthrography Ans: A method of radiographically visualizing the
inside of a joint using a radiolucent or radiopaque contrast
medium
Coronary arteriography Ans: A radiograph or examination of the
heart injected with radiopaque medium
DEXA Ans: Bone densitometry, also called dual-energy x-ray
absorptiometry. Uses a very small dose of ionizing radiation to
measure bone loss
Most accurate method for diagnosing osteoporosis.

Fluorescence Ans: The instantaneous production of light only
during an interaction between a type of energy and some element
or compound
ALARA Ans: As Low As Reasonably Achievable
PACS Ans: Abbreviation for "picture archiving and
communications system"
RIS Ans: (Radiologic information system) Database of radiology
exam-details of all radiologic-specific patient data from patient
scheduling to radiologist's report
Human Diversity Ans: The variety of human societies and cultures
and examines their similarities and differences
These differences are what make each person unique and valuable
in his or her own right.
Cultural Globalization Ans: Globalization means that people now
cross borders into other countries to work, go to school, receive
medical care, visit, and live.
Stereotype Ans: An exaggerated belief, image or distorted truth
about a person or group.

A generalization that allows for little or no individual differences
or social variation.
Ethnocentrism Ans: Belief in the superiority of one's nation or
ethnic group.
Assimilation Ans: the social process of absorbing one cultural
group into harmony with another
Biculturalism Ans: partial identification with two cultures
Tort Ans: Violations of civil law, as opposed to criminal law
Personal injury law
Get compensation for injury
Image receptor Ans: (IR) The device that receives the energy of the
x-ray beam and forms the image of the body part
Heterogeneous Ans: X-ray beams are heterogenous (composed of
different energies)
Continuous Quality Improvement (CQI) Ans: system of
development in the workplace for daily improving performance at
every level in every operational process by focusing on meeting or
exceeding customer expectations
