This anatomical structure MUST be included on upright radiography.
Diaphragm
List 3 criteria for a decubitus radiograph.

List the 2 structures (also list the vertebral level) to bisect when centering for a kidney shot:
1) Xyphoid Process T-10
2) Umbilicus L-4
Which kidney is lower and why?
Right kidney is lower due to liver
The proper centering for a KUB is ____.
Iliac Crest (L4)
KUB stands for what anatomical structures:
Kidneys, Ureters, Bladder
What is the minimum degree that a patient should be elevated when performing an upright abdomen radiograph?
70 degrees; if less must do LLD
What is the proper centering for a bladder shot?
2” bellow ASIS or 2” above pubic symphysis
Why is it important to use the proper respiration when performing abdominal radiography?
Gets diaphrgam up so organs are not compressed and full abdominal cavity may be seen
Why are upright or decubitus radiographs performed?
Demonstrate air and fluid levels.
If performing an upright on a pt who cannot stand completely upright how should the CR be directed to accurately demonstrate air and fluid levels?
CR must remain parallel to the horizon for accurate demonstrate of air and fluid levels
What is the projection of the decubitus abdomen radiograph that has their anterior surface facing the tube?
AP Projection
List an advantage for doing the abdomen using a PA projection?
Greatly reduces pt gonadal dose
What must be included on an upright abdomen radiograph? (from what to what)
Diaphragm to acetabulum
If performing 2 CW radiographs of the abdomen on a large pt what needs to demonstrated on the finished radiographs to ensure that all anatomy is included?
Overlap
When is a diaphragm shot necessary and describe how to perform this radiograph.
Needed when he diaphragm is clipped. Top of IR is at axillary level to ensure diaphragm is on radiograph.
The surgical removal of the gallbladder is ____.
