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 t o a s
radiographs.
REF: p. 4
2. 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
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 protect
i 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-
