1. Theuse of x-rays to create a medicalimage on patients is referred to as
t t t t t t t t t t t t t t
a. electrocardiography.

c. sonography.
d. magnetic resonance imaging. t t
ANS: B t t
Radiography is the making of records of internal structures of the body by t t t t t t t t t t t t
passage of x-rays or gamma rays through the body. These records or images are typically
t t t t t t t t t t t t t t t
referred to as radiographs.

2. Particular care must be taken when using radiation for medical imaging. This is
t t t t t t t t t t t t
the result of radiation’s ability to create
t t in human tissue and possible
t t t t t t t t t t t t
biochemical changes.
t t
a. ionizations
b. radio waves t
c. sound waves t
d. thermal changes t
ANS: A
Some forms of electromagnetic energy, including x-rays, have the ability to ionize
t t t t t t t t t t t
atoms in matter. These ionizations have the ability to disrupt the composition of
t t t t t t t t t t t t t
matter and are capable of disrupting life processes. Special protection should be
t t t t t t t t t t t t
provided to prevent excessive exposure to ionizing radiation.

3. In the diagnosis of patient disease states, physicians can select from an array of
t t t t t t t t t t t t t
medical diagnostic modalities. A few of these involve the use of ionizing
t t t t t t t t t t t t
energy to create a medical image. If a physician is concerned about the use of
t t t t t t t t t t t t t t t
ionizing radiation, he or she may choose to order any of the following
t t t t t t t t t t t t t
diagnostic modalities EXCEPT
t t t
a. thermograms.
b. medical sonography. t
c. radiography.
d. magnetic resonance imaging. t t
ANS: C
Radiography involves the use of x-rays for the production of medical images. t t t t t t t t t t t
Medical procedures such as thermograms, sonograms, and magnetic resonance
t t t t t t t t t
scans use nonionizing energy forms and consequently do not produce
t t t t t t t t t t
ionizations in human tissue. They are regarded as nonionizing modalities for
t t t t t t t t t t t
imaging and offer excellent alternatives to physicians concerned about radiation
t t t t t t t t t t
exposure to patients.

4. The Greek physician Hippocrates is regarded as the father of Western medicine.
t t t t t t t t t t t
tAll of the following choices represent his medical beliefs EXCEPT the
t t t t t t t t t t
a. use of high ethical standards of conduct.
t t t t t t
b. important medical value of sorcery and witchcraft. t t t t t t
c. importance of closely monitoring a patient’s condition and recovery. t t t t t t t t
d. value of diet and exercise and allowing nature to take its course in recovery.
t t t t t t t t t t t t t
ANS: B
The Hippocratic Corpus is writings that they emphasize rational and natural
t t t t t t t t t t
explanations for the treatment of disease and reject sorcery and magic. The
t t t t t t t t t t t t
Hippocratic oath still governs the ethical conduct of physicians today.

5. Throughout the history of medicine, remarkable achievements have been recorded. These
t t t t t t t t t t
tevents have led to our current understanding of the human organism and disease. As
t t t t t t t t t t t t t
t this research continues, much of it will most likely focus on
t t t t t t t t t t
a. proper sanitation and public health. t t t t
b. immunology and the development of vaccines. t t t t t
c. germ theory and infection. t t t
d. human genes and genetic engineering. t t t t
ANS: D
Although the Human Genome Project is finished, analyses of the data will
t t t t t t t t t t t
continue for many years. The replacement of faulty genes through gene therapy
t t t t t t t t t t t t
offers promises of cures for a variety of hereditary diseases, and through genetic
t t t t t t t t t t t t t
engineering, important pharmaceuticals continue to be developed. Medical research
t t t t t t t t t
will continue to focus on the genetic code in all cells.

6. Wilhelm C. Roentgen’s discovery of ―the x-ray‖ is regarded as one of medicine’s
t t t t t t t t t t t t
tmost significant achievements. Although his discovery was accidental, his early
t t t t t t t t t
tresearch was so thorough that no significant findings have been added to his
t t t t t t t t t t t t
t original theories. This in itself is a true tribute to the brilliance of Roentgen as
t t t t t t t t t t t t t t
t a scientist. One of the most famous early images he created was an x-ray image
t t t t t t t t t t t t t t
t of hist
a. colon.
b. laboratory assistant’s foot. t t
c. wife’s hand. t
d. kidneys.
ANS: C
November 8, 1895, is believed by historians to be the day that Roentgen created
t t t t t t t t t t t t t
the famous image of the hand of his wife. Through his investigative
t t t t t t t t t t t t
tmethods, Roentgen identified the properties of x-rays. t t t t t t

, 7. A valuable x-ray procedure used to diagnose a myocardial infarction is
t t t t t t t t t t
a. mammography.
b. myelography.
c. arthrography.
d. coronary arteriography. t
ANS: D
Coronary arteriography is an extremely valuable tool in diagnosing atherosclerosis,
t t t t t t t t t
which can block the coronary arteries and cause a heart attack (myocardial
t t t t t t t t t t t t
infarction). By way of a special catheter with a balloon tip, effective treatment
t t t t t t t t t t t t t
tof atherosclerosis is possible. This treatment of a blocked blood vessel is termed
t t t t t t t t t t t t
tangioplasty. Angioplasty is used to treat patients without having to use invasive t t t t t t t t t t t
open-heart surgery.

t t t t t t t t t t t t
a. it is very valuable for the detection of early breast cancers.
t t t t t t t t t t
b. the procedures may be performed using a general radiographic machine.
t t t t t t t t t
c. radiographers need to be specially trained in order to perform mammography. t t t t t t t t t t
d. radiographers must be certified by the ARRT to qualify for t t t t t t t t t
the mammography examination.
t t t
ANS: B
Special breast imaging centers have been built to accommodate the demand for
t t t t t t t t t t t
tmammography procedures. Equipment and supplies, such as a specially designed x- t t t t t t t t t t
ray tube and high-resolution digital imaging detectors, are used to create high-quality
t t t t t t t t t t t
tbreast images. Mammography cannot be performed using general x-ray
t t t t t t t t
tequipment.

9. To study the blood vessels of the brain, kidneys, liver, and other organs,
t t t t t t t t t t t t
tcontrast material is administered into these vessels by using
t t t t t t t t
a. catheters.
b. stents.
c. balloons.
d. none of the above. t t t
ANS: A
Angiography is the term for radiologic examination of the blood vessels after t t t t t t t t t t t
tinjection of a contrast medium. Most often, the contrast material is injected
t t t t t t t t t t t
through a catheter, which can be directed to a variety of major arteries or veins
t t t t t t t t t t t t t t t
for visualization of these structures.

t t t t t t t t t t t
tmedicine. An imaging modality that uses no ionizing radiation and the energy
t t t t t t t t t t t
tof radio waves and magnetic fields is
t t t t t t
a. nuclear imaging. t
b. thermography.
