Q

Rib considerations Positioning

A

Upright or Recumbent?
•Upper ribs are best demonstrated when patient is upright
•Lower ribs are best demonstrated when patient is recumbent

•Reality: Rib fractures are painful
•If patient can stand: perform all views upright
•If patient is unable to stand: perform all views recumbent

-CR: Perpendicular to center of IR
-Collimation: 14”x17”
-Respiration: Suspend at full inspiration to depress diaphragm

17
Q

AP projection Upper Ribs UNILATERAL

A

•Center between MSP and lateral border of ribs
•Collimation: Check lateral border of ribs and include a little past midline

18
Q

AP projections lower ribs
