Chapter 01: Introduction to Imaging and Radiologic Sciences
Adler: Introduction to Radiologic and Imaging Sciences and Patient Care, 8th Edition
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 as
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 disrupt the composition of matter and are
capable of disrupting life processes. Special protection 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 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 involves the use of x-rays for the production of medical images. Medical
procedures such as thermograms, sonograms, and magnetic resonance scans use nonionizing
energy forms and consequently do not produce ionizations in human tissue. They are
regarded as nonionizing modalities for imaging and offer excellent alternatives to physicians
concerned about radiation exposure to patients.

REF: pp. 3-4
4. 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
The Hippocratic Corpus is writings that they emphasize rational and natural explanations for
the treatment of disease and reject sorcery and magic. The Hippocratic oath still governs the
ethical conduct of physicians today.
REF: p. 5
5. 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
Although the Human Genome Project is finished, analyses of the data will continue for
many years. The replacement of faulty genes through gene therapy offers promises of cures
for a variety of hereditary diseases, and through genetic engineering, important
pharmaceuticals continue to be developed. Medical research will continue to focus on the
genetic code in all cells.
REF: p. 6
6. 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.
c. wife’s hand.
d. kidneys.
ANS: C
November 8, 1895, is believed by historians to be the day that Roentgen created the famous
image of the hand of his wife. Through his investigative methods, Roentgen identified the
properties of x-rays.

7. A valuable x-ray procedure used to diagnose a myocardial infarction is
a. mammography.
b. myelography.
c. arthrography.
d. coronary arteriography.
ANS: D
Coronary arteriography is an extremely valuable tool in diagnosing atherosclerosis, which
can block the coronary arteries and cause a heart attack (myocardial infarction). By way of a
special catheter with a balloon tip, effective treatment of atherosclerosis is possible. This
treatment of a blocked blood vessel is termed angioplasty. Angioplasty is used to treat
patients without having to use invasive open-heart surgery.
REF: p. 8
8. 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
Special breast imaging centers have been built to accommodate the demand for
mammography procedures. Equipment and supplies, such as a specially designed x-ray tube
and high-resolution digital imaging detectors, are used to create high-quality breast images.
Mammography cannot be performed using general x-ray equipment.
REF: p. 8
9. 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
Angiography is the term for radiologic examination of the blood vessels after injection of a
contrast medium. Most often, the contrast material is injected through a catheter, which can
be directed to a variety of major arteries or veins for visualization of these structures.
REF: p. 8
10. Radiologic science continues to be one of the most exciting professions in medicine. An
imaging modality that uses no ionizing radiation and the energy of radio waves and
magnetic fields is
a. nuclear imaging.
b. thermography.
c. CVIT.
