, Chapter 01: Introduction to Imaging and Radiologic Sciences
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.
CORRECT ANSWER: B
Radiography is the making of records, known as radiographs, of internal structures of the body by
passage of x-rays or gamma rays through the body to act on, historically, specially sensitized film or,
most commonly, on a digital imaging plate or detector. In the diagnostic radiography department,
images are created using X-rays that pass through the body.
REF: pp. 3-4
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
CORRECT ANSWER: 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 radiology field, a number of imaging technologies do not employ ionizing radiations. As a
result, the profession is starting to reference a new term that includes medical sonography and
magnetic resonance imaging. This term is often referred to as:
TB
a. x-ray.
b. diagnostic modalities.

,c. imaging sciences.
d. therapeutic services.
CORRECT ANSWER: C
The term imaging sciences has been preferred to the term radiation or radiologic sciences in areas
that use a nonionizing form of radiation such as diagnostic medical sonography and MRI.
REF: p. 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 medicinal potions and super natural powers.
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.
CORRECT ANSWER: B
The Hippocratic Corpus is writings that they emphasize rational and natural explanations for the
treatment of disease and natural recovery and rejects 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 new pharmaceuticals based upon
a. proper sanitation and public health.
b. immunology and the development of vaccines.
c. germ theory and infection.
d. human genes and genetic engineering.
CORRECT ANSWER: 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
TB
developed. Medical research 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 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. hand-held fluoroscope.
CORRECT ANSWER: 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. His methods were so thorough that no significant additions have been made to his work.
REF: p. 6
7. The application of x-rays or gamma rays for disease treatment purposes is referred to as
a. chemotherapy.
b. positron scanning.
c. dual energy absorptiometry.
d. radiation therapy.
CORRECT ANSWER: D
Radiologic technology also involves the use of x-rays or radioactive substances in the treatment of
disease (radiation therapy).
REF: p. 7
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 are be performed using a general radiographic machine.
TB
c. radiographers need to be specially trained in order to perform mammography.
d. 3-D images of the breast can be produced using tomosynthesis.
