Cervical Flashcards
The AP axial projection of the cervical spine will utilize a CR angulation of –1–.

Axis
When performing the Judd Method for the odontoid process, the –1– projection is utilized.
PA
What cervical spine structure will be demonstrated when the patient is rotated 90 degrees?
Zygapophyseal joints
An SID of –1– should be used for lateral projections of the cervical spine.
72”
Explain why the correct SID discussed in question #5 should be utilized.
You are utilizing the air gap technique and it’s less patient dose.

Tip of chin to the mastoid processes

15-20 degrees caudal
What position of the patient will best demonstrate the left intervertebral foramina when using a caudal CR angle?
LAO
What 2 structures should ideally be superimposed when performing the AP projection open mouth position of the cervical spine?
Occlusal plane and the occipital bone of the skull
The Method name for the recumbent “swimmers” position is –1–.
Pawlow
When performing the AP axial projection of the cervical spine, the CR should be directed to –1–.
Thyroid Cartilage
When performing the lateral with flexion, how will the spinous processes be demonstrated?
Widely separated from one another
The Twining Method utilizes a CR angle of –1– if the patient’s remote shoulder cannot be adequately depressed.
5 degrees caudal
The –1– Method will utilize an AP axial oblique projection/position in order to demonstrate the odontoid process and atlanto-axial space.
Kasabch
When performing oblique positions of the cervical spine with the patient in an erect prone position, the foramen that is –1– the IR will be best demonstrated.
Closest to
Why are flexion and extension views performed when doing lateral cervical spine studies?
We are checking to see the mobility of the cervical spine
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?
The chin needs to be elevated more.
Explain why the chin should be jutted up and forward when performing the oblique images of the cervical spine.
It moves the mandable (gonion) out of the way so the structures of the atlas and axis can be visualized.
The “wagging jaw” or –1– Method is used to demonstrate –2–.
- Othonello Method
2. All 7 of the cervical vertebrae
According to Merrills, what line should be placed perpendicular to the IR when performing the AP cervical spine position/projection?
Occlusal Plane
When should the Fuchs Method for the dens be performed?
When the dens is not fully visualized on the AP open mouth
The –1– lateral projection/position if the cervical spine will show the intervertebral spaces widely separated from one another.
Extension
What can be done to eliminate the tongue from obscuring the atlanto-axial space?
Phonate “ah” during the exposure
The joint space between the cervical spine and the skull is called the –1–.
Atlanto-occipital joint space
Where will the dens demonstrated when the Fuchs or Judd Methods are performed?
In the shadow of the Foramen Magnum
This type of curvature is present in the cervical spine.
Lordotic
T or F: All 7 cervical vertebrae will be demonstrated in the routine AP axial projection.
False
T or F: According to Merrills the CR should be perpendicular to the IR if the Fuchs is properly positioned.
True
T or F: The Ottonello Method is a form of autotomography.
True
T or F: It is appropriate for the technologist to remove a cervical collar if the radiographs are cleared by the physician.
False
How should the patient’s arms be placed when performing lateral projection?
Down at their reaching for the ground
When should a “swimmers” position be performed?
When the C7-T1 joint space is not visualized on a neutral lateral cervical
Intervertebral foramen are best demonstrated when the –1– position/projection is performed.
Oblique
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–.
15-20 degrees cephalic
When performing the Pawlow Method for cervical spine the adjacent arm should be –1–.
Elevated
The patient should be rotated –1– degrees when oblique positions are performed.
45 degrees
When performing AP axial obliques, the –1– that is –2– will be best demonstrated.
Intervertebral formamen; furthest from the IR
What structures need to be present on the Pawlow or Twining Methods when performed at Wheeling Hospital?
All anatomy from C1-T3
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.
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.
The Kasabach Method utilizes a CR angle of –1– degrees –2–.
- 10-15 degrees
2. caudal
Whiplash may be demonstrated by using AP and PA axial projections to demonstrate the vertebral –1–.
Pillars
What structures make up the intervertebral foramen?
Inferior and superior vertebral notches
The posterior vertebral arch is formed by the –1–.
Lamina
