ANSWERS. VERIFIED 2026.
Particular care must be taken when using radiation for medical imaging. This is the result of
radiation's ability to create __________ in human tissue and possible biochemical changes.
A. ionizations
B. radio waves
C. sound waves
D. thermal changes - ANS A. ionizations
In the diagnosis of patient disease states, physicians can select from an array of medical
diagnostic modalities. A few of these involve the use of ionizing energy to create a medical
image. If a physician is concerned about the use of ionizing radiation, he or she may choose to
order any of the following diagnostic modalities EXCEPT:
A. thermograms.
B. medical sonography.
C. radiography.
D. magnetic resonance imaging. - ANS C. radiography.
The use of x-rays to create a medical image on patients is referred to as:
A. electrocardiography.

The Greek physician Hippocrates is regarded as the father of Western medicine. All of the
following choices represent his medical beliefs EXCEPT the:
A. use of high ethical standards of conduct.
B. important medical value of sorcery and witchcraft.
C. importance of closely monitoring a patient's condition and recovery.
D. value of diet and exercise and allowing nature to take its course in recovery. - ANS B.
important medical value of sorcery and witchcraft.
Throughout the history of medicine, remarkable achievements have been recorded. These
events have led to our current understanding of the human organism and disease. As this
research continues, much of it will most likely focus on:
A. proper sanitation and public health.
B. immunology and the development of vaccines.
C. germ theory and infection.
D. human genes and genetic engineering. - ANS D. human genes and genetic engineering.
Wilhelm C. Roentgen's discovery of "the x-ray" is regarded as one of medicine's most significant
achievements. Although his discovery was accidental, his early research was so thorough that
no significant findings have been added to his original theories. This in itself is a true tribute to
the brilliance of Roentgen as a scientist. One of the most famous early images he created was
an x-ray image of his:
A. colon.
B. laboratory assistant's foot.

D. kidneys. - ANS C. wife's hand.
A valuable x-ray procedure used to diagnose a myocardial infarction would be:
A. mammography.
B. myelography.
C. arthrography.
D. coronary arteriography. - ANS D. coronary arteriography.
All of the following are true of the diagnostic procedure of mammography EXCEPT:
A. it is very valuable for the detection of early breast cancers.
B. the procedures may be performed using a general radiographic machine.
C. radiographers need to be specially trained in order to perform mammography.
D. radiographers must be certified by the ARRT to qualify for the mammography examination. -
ANS B. the procedures may be performed using a general radiographic machine.
In order to study the blood vessels of the brain, kidneys, liver, and other organs, contrast
material is administered into these vessels by using:
A. catheters.
B. stents.
C. balloons.
D. none of the above. - ANS A. catheters.
