On the grid, anterior to the spine in an upper corner of the collimation field

31
Q

Swimmer’s View: Breathing Instructions

A

Suspended full exhalation (Breathe all the way out and hold completely still)

32
Q

Cervical Pillar View: Purpose

A

Taken in addition to to standard cervical series to provide a better frontal view of the articular pillars

33
Q
