BEST SEEN - RIBS AP - posterior ribs (AD/BD) PA - anterior ribs (AD/BD) OBLIQUES RAO / LPO : LT axillary ribs + RT post rib art w/spine LAO / RPO RT axillary ribs + LT post rib art w/spine
UNIT 3 RT 122 TECHNIQUE CONSIDERATION RIBS : UNILATERAL OR BILATERAL SHORT SCALE CONTRAST NEEDED BONY DETAIL AD – above diaphram 60 – 70 KVP – INSPIRATION BD – below diaphram 70 KVP + 3-4 x more mAs (ABD) EXPIRATION
Routine: Bilateral RIBS Must include : BOTH sides (RT & LT) TOP & Bottom (AED & BD) AP or PA OBLIQUES LPO (RAO) RPO (LAO) (May also include PA CHEST for lungs) ↑ kVp for lungs (90-120)vs kVp bony ribs (60-80)
PA for Chest or Bilat RIBS (AD)
BILAT – AD (upright) 14 x 17 LW CW Centering – same as CXR MSP + T 7
(AP) BILATERAL - AD
Deep Inspiration Why?
INSPIRATION vs EXPIRATION
Why do AP vs PA projection? PA AP
BILAT (BD) 11X14 CW OR 14 x 17 LW Centering – (similar to upper ABD) MSP + L-1 (Bend of Rib) Top of light 1 – 2 “ above xyphoid Bottom of light 1 – 2 “ below IC
OR Upright
