Upper GI Positioning Flashcards
Where do you center for most all upper GI positions?
L1 3-4 inches above crest
What is the degree of obliquity for an RAO upper GI?
40-70 degrees
What is the degree of obliquity on an RAO upper GI for a hypersthenic patient? Asthenic? Sthenic/hyposthenic?
Hypersthenic 70
Asthenic 40
Sthenic/hyposthenic 45-50
What is best demonstrated on an RAO upper GI?
- Entire stomach and duodenum
- Body and pylorus are barium filled
- Duodenal bulb and c-loop shown in profile
Where do you center for a PA upper GI?
L1 an inch left of the vertebral column for the average patient
What is demonstrated on a PA upper GI?
- The body and pylorus are barium filled
- The fundus is air filled
What is demonstrated on a right lateral upper GI?
- The entire stomach and duodenum.
- Retrogastric space
- Vertebrae in true lateral perspective
Why are the pyloric portion of the stomach and c-loop best demonstrated in a right lateral position?
Because the barium empties out of the stomach with the patient laying on their right side
What is the degree of obliquity for an LPO upper GI for a hypersthenic patient? Asthenic? Sthenic/ hyposthenic?
Hypersthenic 60
Asthenic 30
Sthenic/ hyposthenic 45
What is demonstrated on an LPO upper GI?
- The entire stomach and duodenum
- The fundus filled with barium
Where is the CR directed for an AP upper GI?
L1 midway between the outer margin of the body Dan the midsagital plane
What is demonstrated on an AP upper GI?
- Entire stomach and duodenum
- Fundus filled with barium
If the patient is supine which part of the stomach should be air filled?
The body and pyloric region
If the patient is prone which portion of the stomach should be air filled?
The fundus
If the patient is erect which portion of the stomach should be air filled?
The fundus and some of the body
