AP projection used for Barium Enemas that best demonstrates the Right (hepatic) flexure and the ascending colon?
Patient prep for a Barium Enema
-Dietary restrictions (clear liquids only) and a bowel cleansing regimen
-May be omitted in cases of suspected bowel obstruction or volvulus, colostomy pts., prolonged diarrhea, or severe rectal bleeding.
Single contrast studies
When using a Barium Enema they best demonstrate:

What does a lateral decubitus abdomen with a double contrast study best demonstrate?
Lateral ascending colon and medial descending colon
Where is the air in a left lateral decubitus abdomen when using a double contrast study?
Lateral descending colon and medial ascending colon
Where is the air in a right lateral decubitus abdomen when using a double contrast study?
Rectosigmoid area of the colon
What is best visualized in the PA Axial of the colon?
Pyloric canal and the duodenal bulb
What is best visualized in the Upper GI RAO position?
To see hiatal hernias
Why would you use the Trendelenburg position for an Upper GI?
What are the joint tissue that makes up the sutures of the skull?
Towne method (AP Axial)
Which method best demonstrates the occipital bone?

If you have an AP Axial projection of the skull and you can't get the OML perpendicular, how would you compensate?
Caldwell (PA/PA Axial)
What method would best demonstrate the frontal bone?
Structures best demonstrated are:
-Posterior clinoid process
-Dorsum sellae (in middle of foramen magnum)
-CR for a trauma patient: Enters the acanthion while continuing to be parallel to the MML
