Digestive System UGI SBS BASW Review Flashcards
The most anterior part of the stomach is the –1–.
Pylorus
The –1– position will best demonstrate the esophagus without superimposition on the heart or spine.
RAO
The recommended degree of obliquity for an unobstructed image of the esophagus is –1– degrees.
35-40 degrees
This portion of the small bowel has a “feathery” appearance.
Jejunum
The most superior portion of the stomach is the –1–.
Fundus
What type of Kv is necessary for adequate penetration during barium studies?
High
Digestion and absorption takes place in this portion of the alimentary tract.
Small Intestines
The normal emptying for the stomach is approximately –1–.
2-3 hours
The medical term for swallowing is –1–.
Deglutition
When the patient who has had barium is lying prone, the barium will be located in this portion of the stomach.
Pylorus
List 3 ways that gas products can be introduced for a barium study.
- Gas Crystals
- Carbonated Beverage
- Poke holes in the straw the patient is drinking from
The CR should be directed to the vertebral level of –1– for a stomach follow-up radiograph. What bony landmark is at this level that is used for stomach centering?
- L1-L2
2. Costophrenic angle
How will the stomach be demonstrated in the LAO or RPO position?
Elongated
How much should the patient be rotated when performing oblique images of the stomach?
40-70 degrees
Which positioning of the stomach will demonstrate the entire duodenal loop?
Right Lateral, AP, and PA.
Which projection, PA or AP is preferred when demonstrating the small intestines?
PA
What is another name for the LES?
Cardiac Sphincter/ Lower Esophageal Sphincter
Where should the IR be placed when performing BASW f/u radiographs?
Top of IR placed at EAM
The stomach lies in which quadrant?
Left Upper Quadrant
What is rugae and what is its main function?
Rugae are the folds in stomach lining that allow for the stomach to expand. Rugae gives the stomach more area.
Name 2 pathologies that the Valsalva Maneuver will demonstrate during barium studies of the upper digestive tract.
Esophageal Varacies and GERD
Why would barium not be the contrast of choice if a patient has a suspected perforation?
Barium does not get absorbed by the body. You would want to use a water soluble contrast.
What is the term for a wavelike movement of food through the digestive tract?
Peristalsis
What position will best demonstrate the duodenal bulb?
RAO
The structure that allows passage of food/ barium from the small intestines into the large intestines is called the –1–.
Ileocecal Valve
A thinner suspending medium…
will pass quicker
A thicker suspending medium…
will pass slower
A cooler suspending medium…
will pass quicker
A warmer suspending medium…
will pass slower
A patient with a disease or blockage…
will pass slower
What type of contrast should be used if there is a suspected perforation in the digestive tract and why?
A water soluble contrast should be used because if it leaks into the abdominal cavity it will be absorbed by the body.
What is meant by the term “full column” or single contrast study of the esophagus?
You are trying to see the esophagus filled with barium by swallowing one thickness of barium and taking the exposure while it is filled when the patient swallows.
Where do we center for oblique views of the esophagus?
2’’ from MSP toward side up (L) when done prone
List the proper prep for the following exams.
- BASW
- UGI
- SBS
- No prep needed
- NPO since midnight
- NPO
What position may better demonstrate hiatal hernias?
Trendelenburg
If a patient is positioned in an upright AP projection describe where the barium and air will be.
Barium in the Pylorus
Air in the Fundus
Explain what happens to the stomach if the patient is hypersthenic.
The stomach lays high, is elongated, is away from midline and more horizontal.
What will the radiographer do in regard to the patient rotation when performing oblique stomach views for the hypersthenic patient?
The radiographer will oblique the patient more.
Which section of the small bowel is the shortest?
Duodenum
Name the three organs with ducts that enter/empty into the small bowel?
- Liver
- Pancreas
- Gallbladder
Referring to question #40, these organs (Liver, Pancreas, Gallbladder) are referred to as the –1– system.
Billiary
What organ is part of both the respiratory and digestive systems?
Pharynx
What is the correct vertebral level used when centering for an esophagus study?
T5-T6
The esophagus joins the stomach at the esophagogastric junction, which is at the vertebral level of –1–.
T11
The duodenaljejunal flexure is suspended by the –1–.
Ligament of Trietz
