(18 cards)
Structures AP
C7 to L1 including all 12 thoracic vertebrae
CR and CP AP
CR: perp
CP:T7
No rotation AP
Shoulder: medial ends of clavicle are equidistant to VB
SP equidistant to pedicles
Pelvis: SP equidistant to pedicles
No waist f/e AP
Open IV joint space
No distortion of vertebral bodies
Phase of respiration AP
Domes of diaphragm at ~T8-9 for expiration
Motion artifacts AP
Suspended expiration indicated by:
Sharp diaphragms
Sharp margins if ribs
Sharp lung markings
Structures Lat
C7-L1
Posterior rib margins
CR and CP lat
CR: perp or 10-15 Cephalad if shoulders are wide and spine not // to tabletop
CP: T7
No rotation Lat
Main: posterior margin of vertebral bodies SI ant/ post
Posterior ribs will not be perfectly SI ant/post
No tilt Lat
Intervertebral spaces open when thoracic spine is // to ir
Posterior ribs are in same transverse level
Phase of respiration lat
Breathing technique preferred or on expiration
Motion artifacts breathing technique
Shallow breathing
Blurred diaphragm

Structure Swimmer
C5-T3
CR and CP swimmers
CR: perp
May need to add caudal angle if they can’t depress shoulders
CP: midline at c7/t1
No rotation Swimmerd
Main: post margins of VB SI ant/post
Z joints SI ant/post
No tilt swimmers
Intervertebral disk spaces open
