a. inferior
b. superior
c. at the same level

Answer 5

b. superior

Question 6

To obtain open intervertebral disk spaces for AP axial cervical vertebrae projections when imaging the upright and kyphotic patient, the central ray:
a. angulation needs to be increased over that used on the supine patient.
b. should be angled caudally.
c. should remain horizontal.
d. angulation needs to be decreased over that used on the supine patient.

Answer 6

a.angulation needs to be increased over that used on the supine patient.

Question 7

b. the pt is underrotated

Answer 7

a. the pt is overrotated

Question 8

A less than optimal lateral cervical vertebrae projection demonstrates the articular pillars of one side of the patient situated anterior to the opposite articular pillars. How was the patient mispositioned?
a. The midcoronal plane was not aligned parallel to the IR.
b. The midsagittal plane was not aligned perpendicular to the IR.
c. The midcoronal plane was not aligned perpendicular to the IR.
d. The acanthiomeatal line was not parallel with the floor.

Answer 8

c. The midcoronal plane was not aligned perpendicular to the IR.

Question 9

An AP Open Mouth (atlas and axis projection) with accurate positioning demonstrates all of the following except:
a. the first through fourth cervical vertebrae.
b. the upper incisors and occipital base are seen superior to the dens.
c. lateral masses equidistant to the dens.
d. an open atlantoaxial joint.

Answer 9

a. the first through fourth cervical vertebrae.

Question 10

An AP Open Mouth (atlas and axis projection) with poor positioning demonstrates the upper incisors obscuring the dens and atlantoaxial joint. How was the positioning setup mispositioned for such an image to be obtained?
1. The patient’s face was rotated toward the left side.
2. The patient’s chin was elevated more than needed.
3. The patient’s chin was tucked more than needed.
4. An imaginary line connecting the occlusal plane and posterior occiput’s inferior edge was not aligned perpendicular to the imaging table.

Answer 10

3 and 4 only

Question 11

A lateral cervical projection with accurate positioning demonstrates:
1. C1 and C2 without cranial or mandibular superimposition.
2. open intervertebral disk spaces.
3. superimposed right and left articular pillars and zygapophyseal joints.
4. the spinous process in profile.

Answer 11

1, 2, 3, and 4

Question 12

A lateral cervical projection obtained with the patient’s head tilted toward the IR demonstrates the:
a. posterior arch of C1 in profile
b. vertebral foramen of C1.

Answer 12

b. vertebral foramen of C1.

Question 13

Which of the following projections or positions demonstrates the right intervertebral foramina?
1. Lateral
2. LPO
3. LAO
4. RAO

Answer 13

2 and 4 only

Question 14

An AP thoracic projection with accurate positioning demonstrates all of the following except:
a. open intervertebral joint spaces.
b. equal interpediculate spaces.
c. distorted vertebral bodies.
d. spinous processes aligned with the midline of the vertebral bodies.

Answer 14
