Which foramina are demonstrated with a left posterior oblique (LPO) position of the cervical spine?

• The left intervertebral foramina (downside)

• The right intervertebral foramina (upside)

• The right intervertebral foramina (downside)

• The left intervertebral foramina (upside)

The zygapophyseal joints for the typical cervical vertebra lie at an angle of _____ in relation to the midsagittal plane.

• 30 degrees

• 45 degrees

• 70 degrees

• 90 degrees

Name the special projection.

• LAO

• AP Axial Oblique Projection (Pillars)

• RPO

• Cervicothoracic (Swimmer’s) lateral projection

Which structures are unique to the Cervical vertebrae?

• Costal Facets

• Bifid Tips

• Transverse Foramen

• Zygapophyseal joints

An image of an AP axial projection of the C-spine reveals that the intervertebral joints are not open. The following factors were used: CR centered to the thyroid cartilage with a 5 degree angle cephalad, 40 inch SID, grid, slight extension of the skull. Which correction should be made?

• Increase cephalic angle to 15 degrees

• Increase caudal angle to 15 degrees

• Decrease cephalic angle to 5 degrees

• Remove tube angle. CR should be perpendicular.

A lateral cervical spine projection shows the ramus of the mandible superimposed over the anatomy of interest. Which action should the technologist take when positioning for the repeat image to ensure that the same error does not occur?

• Increase the extension of the skull

• Angle the CR 10-15 degrees caudad

• Increase the flexion of the skull

• Have the patient hold 5-10 pounds in each hand

Name the special projection.

• Closed mouth odontoid AP view (Fuchs view)

• Open mouth odontoid AP view

• Wagging jaw (Ottonello Method)

• Cervicothoracic (Swimmer’s) lateral projection

The odontoid is located on the superior aspect of _____ and articulates with the anterior arch of _____.

• C1, C2

• C2, C1

• C7, T1

• C2, C3

When a patient has an abnormal lateral curvature of the spine it is referred to as

A radiograph of a right posterior oblique (RPO) cervical spine shows that the lower intervertebral foramina are not open. The upper intervertebral foramina are well visualized. What positioning error has occurred?

• The patient's upper body is under-rotated.

• The CR angle is wrong. Increase the CR angle to 15 degrees cephalad.

• The patient has significant trauma.

• The patient was placed in a lateral position.
