Q

If an AP open mouth position is performed and the resulting image shows teeth over the atlanto-axial space, what positioning improvements should be made to improve the image?

A

The chin needs to be elevated more.

19
Q

Explain why the chin should be jutted up and forward when performing the oblique images of the cervical spine.

A

It moves the mandable (gonion) out of the way so the structures of the atlas and axis can be visualized.

20
Q

The “wagging jaw” or –1– Method is used to demonstrate –2–.

A
  1. Othonello Method

2. All 7 of the cervical vertebrae

21
Q

According to Merrills, what line should be placed perpendicular to the IR when performing the AP cervical spine position/projection?

A

Occlusal Plane

22
Q

When should the Fuchs Method for the dens be performed?

A

When the dens is not fully visualized on the AP open mouth

23
Q

The –1– lateral projection/position if the cervical spine will show the intervertebral spaces widely separated from one another.

A

Extension

24
Q

What can be done to eliminate the tongue from obscuring the atlanto-axial space?

A

Phonate “ah” during the exposure

25
Q

The joint space between the cervical spine and the skull is called the –1–.

A

Atlanto-occipital joint space

26
Q

Where will the dens demonstrated when the Fuchs or Judd Methods are performed?

A

In the shadow of the Foramen Magnum

27
Q

This type of curvature is present in the cervical spine.

A

Lordotic

28
Q

T or F: All 7 cervical vertebrae will be demonstrated in the routine AP axial projection.

A

False

29
Q

T or F: According to Merrills the CR should be perpendicular to the IR if the Fuchs is properly positioned.

A

True

30
Q

T or F: The Ottonello Method is a form of autotomography.

A

True

31
Q

T or F: It is appropriate for the technologist to remove a cervical collar if the radiographs are cleared by the physician.

A

False

32
Q

How should the patient’s arms be placed when performing lateral projection?

A

Down at their reaching for the ground

33
Q

When should a “swimmers” position be performed?

A

When the C7-T1 joint space is not visualized on a neutral lateral cervical

34
Q

Intervertebral foramen are best demonstrated when the –1– position/projection is performed.

A

Oblique

35
Q

When performing AP axial oblique projections of the cervical spine on a patient who is lying on an exam table, the CR should be directed to C4 at an angle of –1–.

A

15-20 degrees cephalic

36
Q

When performing the Pawlow Method for cervical spine the adjacent arm should be –1–.

A

Elevated

37
Q

The patient should be rotated –1– degrees when oblique positions are performed.

A

45 degrees

38
Q

When performing AP axial obliques, the –1– that is –2– will be best demonstrated.

A

Intervertebral formamen; furthest from the IR

39
Q

What structures need to be present on the Pawlow or Twining Methods when performed at Wheeling Hospital?

A

All anatomy from C1-T3

40
Q

When a patient can neither be erect nor rolled for oblique cervical radiographs due to a trauma situation an ETA must be utilized to obtain the oblique radiographs. What does ETA stand for and briefly describe what will be done to achieve this.

A

Eccentric Tube Angulation- angle the tube 45 degrees in necessary direction and angle the tube 15-20 degrees cephalic if pt is supine or 15-20 degrees caudal if patient is prone.

41
Q

The Kasabach Method utilizes a CR angle of –1– degrees –2–.

A
  1. 10-15 degrees

2. caudal

42
Q

Whiplash may be demonstrated by using AP and PA axial projections to demonstrate the vertebral –1–.

A

Pillars

43
Q

What structures make up the intervertebral foramen?

A

Inferior and superior vertebral notches

44
Q

The posterior vertebral arch is formed by the –1–.

A

Lamina
