1. Which of the following projections will project the dens within the shadow
of the foramen magnum? - ANSWER Fuchs method
2. A radiograph of an AP open-mouth projection of the cervical spine reveals
that the zygapophyseal joints are not symmetric. What position error can
lead to this radiographic outcome? - ANSWER rotation of spine
3. A radiograph of an AP axial projection of the cervical spine reveals that the
intervertebral joints are not open. The following factors were used for this
projection: 5-degree cephalad angle, 40-inch (100 cm) SID, grid, slight
extension of the skull, and the CR centered to the thyroid cartilage. Which
alteration should be made for the repeat exposure? - ANSWER increase
the CR angulation
4. A radiograph of a lateral thoracic spine reveals that there is excessive
density along the posterior aspect of the spine. Even with good collimation,
the scatter radiation reaching the image receptor obscures the spinous
processes. What can the technologist do to improve the visibility of the
, posterior elements of the spine? - ANSWER Place a lead mat on the
tabletop posterior to the patient
5. A radiograph of a lateral projection of the cervical spine reveals that the
ramus of the mandible is superimposed over the spine. What could the
technologist have done to prevent this? - ANSWER increase the
extension of the skull
6. Situation: a patient enters the ED due to a motor vehicle accident. the
patient is on a back board and wearing a cervical collar. The technologist is
concerned about the artifacts that the collar will project on the spine during
the horizontal beam lateral projection. What should he do in this situation
for the first cervical spine projection? - ANSWER leave the collar on
during exposure
7. Situation: A lateral projection of the thoracic spine reveals that the upper
aspect, which is a primary are of interest on this patient, is obscured by the
patient's shoulder. Which of the following changes will best demonstrate
this region of the spine? - ANSWER perform a swimmer's lateral
projection
8. Situation: A patients enters the ED with a cervical spine injury due to a fall.
The initial horizontal beam lateral projection reveals no subluxation of
fracture. The ED physician is concerned about a whiplash injury. Which of
the following routines would be most helpful in the diagnosing this type of
injury? - ANSWER Patient in flexion and extension lateral positions
,9. Which one of the following projections will best demonstrate a
compression fracture of the thoracic spine? - ANSWER lateral projection
10.Situation: A patient enters the ED, He is on a back board and in a cervical
collar. The initial lateral cervical spine projection demonstrates C1 to C6.
The patient has broad and thick shoulders. Because the hospital is in rural
setting, no CT scanner is available. What should the technologist do next? -
ANSWER Perform horizontal beam swimmer's lateral projection
11.The right intervertebral foramina are best demonstrated on which
projection of the cervical spine? - ANSWER RAO and LPO
12.The intervertebral foramina of the lumbar spine are located at an angle of
_____-in relation to the midsagittal plane - ANSWER 90 degrees
13.The zygapophyseal joints of the upper lumbar (L1-2) vertebrae are ______
in relationship to the midsagittal plane. - ANSWER 50 degrees
14.What is the term for the superior aspect of the coccyx? - ANSWER base
15.The Scotty dog sign is demonstrated with oblique projections of the thoracic
and lumbar spine - ANSWER false
16.The average degree of rotation required to demonstrate the L3-4
zygapophyseal joints is: - ANSWER 45 degrees
, 17.If the waist is supported properly, an average-size patient does not require
any CR angulation of the lateral lumbar spine projection - ANSWER true
18.What CR angulation should be used for an AP axial projection of the L5-S1
joint space is - ANSWER 30 to 35 degrees cephalad
19.A radiographic appearance on an oblique lumbar spine in which the neck of
the Scotty dog appears broken suggests the presence of ______. - ANSWER
spondylolysis
20.An anterior wedging of vertebrae with a loss of body height but rarely
causing neurologic symptoms is called: - ANSWER compression fracture
21.Sciatic-type pain resulting from a "slipped disk" indicates: - ANSWER
Herniated nucleus pulposus
22.What CR angle should be used for a lateral sacrum/coccyx projection? -
ANSWER None. CR is perpendicular to the image receptor
23.A radiograph of an LPO projection of the lumbar spine reveals that the
downside pedicle is projected too far posterior in the vertebral body. What
specific positioning error is present on the radiograph? - ANSWER
Excessive rotation of the spine
24.The neck of the scotty dog represents? - ANSWER pars interarticularis
