Where does the CR go for an AP cervical?
C4 (thyroid cartilage)
What is the collimation for an AP cervical?
8x10
What anatomy must be present for an AP cervical?
C3 to T1 and lung apices
What bony feature is superimposed over the base of the occiput in an AP cervical?
Bottom of mandible
What is at the center of an AP cervical film?
C4
What imaging study is considered the best choice to exclude fracture according to ACR?
High-resolution CT
What is the SID for anterior cervical obliques?
72
What is the SID for all cervical views except APOM and AP cervical?
72
What is the SID for APOM and AP cervical?
40
For an anterior cervical oblique, the patient must be rotated how many degrees away from the PA position?
45
What is the tube tilt for anterior cervical obliques?
15 degrees caudal
What is the collimation for anterior cervical obliques?
8x10
What two cervical films don’t have an 8x10 collimation?
APOM, flexion/extension lateral
Which cervical series have tube tilts?
Anterior obliques = 15 caudal
Posterior obliques = 15 cephalic
AP cervical - 15 cephalic
What are the breathing exercises for all cervical views?
Exhale and hold (for AP and APOM, you can also use “don’t breathe and don’t move”)
Which IVFs are visible with right anterior cervical obliques?
Right
Which IVFs are visible with left anterior cervical obliques?
Left
What anatomy must be present for anterior cervical obliques?
Base of occiput to T1
What is the purpose of flexion/extension lateral views?
Demonstrate ligament instability and range of motion
What is the collimation for flexion/extension lateral views?
Leave open at 10x12
Where do we measure calipers for the swimmer’s view?
Under the arms, axilla to axilla
Which arm is raised for a swimmer’s view?
One closest to film
Where is the CR for a swimmer’s view?
T1
What is the breathing instruction for the swimmer’s view?
Exhale and hold
What is the purpose for the raised arm with swimmer’s?
Acts as a natural filter for cervical spine
A tube tilt of how many degrees and in which direction MAY be used for swimmer’s?
5 degree caudal
For a right swimmer’s view, which humerus is visible on the inferior aspect of the film?
Left
Seating during the cervical series helps to avoid what kind of posture?
Military neck
Which is preferred: anterior or posterior cervical obliques and why?
Anterior; radiation protection and shoots into concavity
What 5 set ups are all done at 72 SID?
All lateral cervicals, all cervical obliques, PA chest, lateral chest, AP full spine
