21
Q

For an anterior cervical oblique, the patient must be rotated how many degrees away from the PA position?

A

45

22
Q

What is the tube tilt for anterior cervical obliques?

A

15 degrees caudal

23
Q

What is the collimation for anterior cervical obliques?

A

26
Q

What are the breathing exercises for all cervical views?

A

Exhale and hold (for AP and APOM, you can also use “don’t breathe and don’t move”)

27
Q

Which IVFs are visible with right anterior cervical obliques?

A

Right

28
Q

Which IVFs are visible with left anterior cervical obliques?

A

Left

29
Q

What anatomy must be present for anterior cervical obliques?

A

Base of occiput to T1

30
Q

What is the purpose of flexion/extension lateral views?

A

Demonstrate ligament instability and range of motion

31
Q

What is the collimation for flexion/extension lateral views?

A

Leave open at 10x12

32
Q

Where do we measure calipers for the swimmer’s view?

A

Under the arms, axilla to axilla

33
Q

Which arm is raised for a swimmer’s view?

A

One closest to film

34
Q

Where is the CR for a swimmer’s view?

A

T1

35
Q

What is the breathing instruction for the swimmer’s view?

A

Exhale and hold

36
Q

What is the purpose for the raised arm with swimmer’s?

A

Acts as a natural filter for cervical spine

37
Q

A tube tilt of how many degrees and in which direction MAY be used for swimmer’s?

A

5 degree caudal

38
Q

For a right swimmer’s view, which humerus is visible on the inferior aspect of the film?

A

Left

39
Q

Seating during the cervical series helps to avoid what kind of posture?

A

Military neck

40
Q

Which is preferred: anterior or posterior cervical obliques and why?

A

Anterior; radiation protection and shoots into concavity

41
Q

What 5 set ups are all done at 72 SID?

A

All lateral cervicals, all cervical obliques, PA chest, lateral chest, AP full spine
