|
Why do you do an AP KUB instead of a PA KUB for an OCG?

FULL EXPIRATION
It moves 1-3" superiorly and laterally. FULL INSPIRATION It moves 1-3" inferiorly and medially |

|
You may see a horizontal line in the gallbladder when doing the uprights.
|
|
What is the Rt. Lat. Decub. done to see?
|
MOST IMPORTANT PICTURE
Because it shows stratification or laying of stones better than uprights. |
