The CR for the PA axial projection of the sigmoid colon?
30 degrees caudal
Rotating the patients body ____ degrees into the LPO position, places the ____ kidney parallel to the IR?
30, right
To demonstrate esophageal varices, the patient must be examined in the __________ position?
Recumbent
The ______ ________ position is often used during an upper GI examination to demonstrate hiatal hernias?
AP Trendelenburg
Which radiographic position should be used to best demonstrate the duodenal loop and the duodenojejunal junction filled with contrast medium?
Recumbent Right Lateral
During an air-contrast BE, in what part of the colon is air most likely to be visualized with the body in the AP recumbent position?
Transverse Colon
Which position will best demonstrate possible nephroptosis?
Erect
What two oblique positions can be used to demonstrate the entire esophagus effectively?
RAO and LPO
For the double-contrast UGI examination, which projection produces the best image of the gas-filled duodenal bulb and pyloric canal?
Recumbent LPO position
Which positions can be used to effectively demonstrate the left colic flexure during radiographic exam of the large bowel?
RPO and LAO
What is best demonstrated in the RAO position?
Right colic flexure, ascending and sigmoid colon are "open"
During an intravenous urogram (IVU), the RPO position is used to demonstrate the:
1. Left kidney parallel to the IR
2. Right kidney parallel to the IR
3. Right kidney perpendicular to the IR
1 and 3
Why is the recumbent RAO position preferred over the upright position for the esophageal image?
Allows for more complete contrast filling of the esophagus
Single-contrast UGI examinations with the patient recumbent, which projection produces the best image of a barium-filled pyloric canal and duodenal bulb in patients with a sthenic body habitus type?
RAO position
Double-contrast exams of the stomach or large bowel are performed to better visualize the _______?
Gastric or bowel mucosa
What structure must be included on the scout, AP projection during a routine BE exam?
Symphysis Pubis
To enhance filling of the major and minor calyces of the kidney if ureteric compression is contraindicated, what can be done?
Place patient in a 15 degree Trendelenburg position
A large out-pouching of the upper esophagus is termed
Zenker's Diverticulum
An upper GI series is performed on a hypersthenic patient. A radiograph of the RAO position reveals that the duodenal bulb and C loop are not in profile. The technologist had rotated the patient 40 degrees. What modification of the position is required during the repeat exposure?
Increase patient rotation to more than 60 degrees
This projection decreases OID and spreads the bowels for better visualization
PA
The left lateral position best demonstrates ______?
Contrast-filled rectosigmoid region
What specific position is recommended for a male patient during a voided cystourethrogram?
30 degree RPO
