Cervical Spine Flashcards
The AP axial cervical spine CR is:
angles 15-20 degrees cephalic to the level of C4
The AP axial cervical spine SID:
100 cm
What is the purpose of the angulation on the tube of the AP axial cervical spine:
Open up the joint spaces, intervertebral disk spaces
AP open mouth should show a clear view of the _________ to allow the head to pivot side to side.
C1-C2 articulation
With the mouth fully wide open the occlusal plane is:
Perpendicular
An imaginary line drawn from the lower margin of the upper incisors to the tip of the mastoid process (base of the skull):
Occlusal plane
If the base of the skull are superimposed over the odontoid:
flex the head and neck
bring the chin down
The teeth are superimposing the odontoid process:
bring the chin up
extend the head and neck
A lateral Cervical spine is performed with a __________ SID.
180 cm
Can you count on a lateral c-spine, 7 cervical vertebrae, and do not see the articulation of C1. What do you do next?
laterocervical thoracic projection
Use hand weights to relax the shoulders down and completely show the area
Someone comes in immobilized on a spine board what are you going to do?
horizontal beam lateral
properly get it cleared by attending physician
In an anterior oblique of the cervical spine what is best demonstrated?
Intervertebral foramana
If the patient is facing the x-ray tube
15-20 degrees cephalic
if the patient’s back is to the x-ray tube:
15-20 degrees cuadad
When you are in anterior oblique position you best demonstrate the:
intervertebral foramina closest to the IR
