MULTIPLE CHOICE
1. The use of x-rays to create a medical image on patients is referred to as
a. electrocardiography.
b. radiography.
c. sonography.
d. magnetic resonance imaging.
ANS: B
Radiography is the making of records of internal structures of the body by passage of x-
rays or gamma rays through the body. These records or images are typically referred to a
s radiographs.
REF: p. 4
2. Particular care must be taken when using radiation for medical imaging. This is the result 6
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
Some forms of electromagnetic energy, including x-
rays, have the ability to ionize atoms in matter. These ionizations have the ability to disru
pt the composition of matter and are capable of disrupting life processes. Special protecti
on should be provided to prevent excessive exposure to ionizing radiation.
REF: p. 3
3. 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 medi
cal 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 involves the use of x-
rays for the production of medical images. Medical procedures such as thermograms, sono
grams, and magnetic resonance scans use nonionizing energy forms and consequently do
not produce ionizations in human tissue. They are regarded as nonionizing modalities for i
maging and offer excellent alternatives to physicians concerned about radiation exposure t
o patients.
