Ribs & Sternum

Question 1

RAO Sternum

Answer 1

kVp: 70
mA: 30
40 inch SID

20 degrees RAO
ULB 1 inch above jugular notch
CR midway between jugular & xiphoid tip
Medial light border at spine
Breathing techniques 3-4 seconds or suspended expiration

Best seen RAO because of teen heart
LPO if needed

Question 2

Lateral sternum

Answer 2

kVp: 75
mAs:30
72 SID

ULB 1 -2 inches above jugular notch
Sternum aligned with CR
Arms above head out the way
Expose on full inspiration

Question 3

PA SC joints

Answer 3

kVp: 75
mAs: 30
SID: 40 inches

CR @ T3 level with SC joint
Take a breath in, blow it out and hold

Question 4

Oblique SC Joints

Answer 4

kVp: 75
mAs:30
SID : 40

15 degree rotation towards ROI
CR @T3 and 2 inches lateral of spine

THE DOWNSIDE SC JOINT IS THE ONE BEST VISUALIZED

CR for upper ribs @T7 (3-4 inches below jugular notch) & midline
Top of IR 1.5 inch above shoulders
Roll shoulders forwards
Take a breath and and hold

CR for lower ribs midway between xiphoid tip
Raise chin to prevent superimposing upper ribs
Roll shoulders forward
Take a breath in, blow it out and hold

Question 6

Answer 6

kVp: 75
mAs: 30
SID :40

CR: upper ribs @T7 (3-4 inches below jugular notch) & midline
Top of IR 1.5 inch above shoulders
Roll shoulders forwards
Take a breath and and hold

CR for lower ribs midway between xiphoid tip
Raise chin to prevent superimposing upper ribs
Roll shoulders forward
Take a breath in, blow it out and hold

Question 7

Oblique ribs

Answer 7

kVp: 75
mAs: 30
SID: 72

Rotate patient 45 degrees RPO/LPO
CR: upper ribs @T7 (3-4 inches below jugular notch) & midline
Top of IR 1.5 inch above shoulders
