RTE 1523C Final Exam Questions and
Correct Answers Updated
Question 1
A patient comes to the radiology department for a cervical spine routine. The study is
ordered for nontraumatic reasons. The AP open mouth projection reveals that the
base of the skull and upper incisors are superimposed, but they are obscuring the
upper portion of the dens. On the repeat exposure, what should the technologist do
to demonstrate the upper portion of the dens?
Correct Answer
do fuchs or judd



Question 2
A radiograph of an AP open-mouth projection of the cervical spine reveals that the
zygapophyseal joints are not symmetric. No fracture or subluxation is present. Which
one of the following positioning errors most likely led to this radiographic outcome?

Correct Answer
rotation of the spine



Question 3
The intervertebral foramina of the thoracic spine form an angle of how many degrees
with the midsagittal plane?
Correct Answer
90

,Question 4
An AP axial cervical projection obtained with the patient rotated toward the right side
demonstrates
1. the spinous processes positioned closer to the left side of the vertebral bodies.
2. closed intervertebral joint spaces.
3. elongation of the uncinate processes.
4. the left SC superimposed over the vertebral column.
Correct Answer
1 and 4 only



Question 5

Correct Answer
L3-4



Question 8

vertebra superimposed over the posterior occipital bone. How should the positioning
setup be adjusted to obtain an optimal projection?

,Question 9
Where is the IR centered for a hyperflexion or hyperextension lateral projection of the
cervical spine?
Correct Answer
fourth cervical vertebra



Question 10
An AP axial cervical projection with poor positioning demonstrates obscured
intervertebral disk spaces and each vertebra's spinous process within its vertebral
body. How was the positioning setup mispositioned for such a projection to be
obtained?
Correct Answer
The central ray had an insufficient cephalic angle.



Question 11
A patient enters the ED with a cervical spine injury as a result of a fall. The initial
horizontal beam lateral projection reveals no subluxation or fracture. The ED physician
is concerned about a whiplash injury. Which of the following routines would be most
helpful in diagnosing this type of injury?
Correct Answer
Patient in hyperflexion and hyperextension lateral positions



Question 12
Scoliosis is defined as an abnormal or exaggerated _____ curvature.
Correct Answer
lateral



Question 13
Where does the central ray enter the body for the AP axial projection (Ferguson
method) of the lumbosacral junction?
Correct Answer
ASIS

, Question 14
A patient comes to radiology for a thoracic spine routine. The patient has a history of
arthritis of the spine. The radiologist requests that additional projections be taken to
demonstrate the zygapophyseal joints. What position(s) and/or projection(s) would be
ideal to demonstrate these structures?
Correct Answer
70 degree oblique



Question 15
Where should the superior edge of the IR/collimated field be placed for an AP
projection of the thoracic vertebrae?
Correct Answer
1 1/2 to 2 inches above the shoulders



Question 16

unite posteriorly.
Correct Answer
lamina



Question 17
Dense material, like bone, is considered:
Correct Answer
radiopaque



Question 18
