Q

What is rugae and what is its main function?

A

Rugae are the folds in stomach lining that allow for the stomach to expand. Rugae gives the stomach more area.

21
Q

Name 2 pathologies that the Valsalva Maneuver will demonstrate during barium studies of the upper digestive tract.

A

Esophageal Varacies and GERD

22
Q

Why would barium not be the contrast of choice if a patient has a suspected perforation?

A

Barium does not get absorbed by the body. You would want to use a water soluble contrast.

23
Q

What is the term for a wavelike movement of food through the digestive tract?

A

Peristalsis

24
Q

What position will best demonstrate the duodenal bulb?

A

RAO

25
Q

The structure that allows passage of food/ barium from the small intestines into the large intestines is called the –1–.

A

Ileocecal Valve

26
Q

A thinner suspending medium…

A

will pass quicker

27
Q

A thicker suspending medium…

A

will pass slower

28
Q

A cooler suspending medium…

A

will pass quicker

29
Q

A warmer suspending medium…

A

will pass slower

30

31
Q

What type of contrast should be used if there is a suspected perforation in the digestive tract and why?

A

A water soluble contrast should be used because if it leaks into the abdominal cavity it will be absorbed by the body.

32
Q

What is meant by the term “full column” or single contrast study of the esophagus?

A

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.

33
Q

Where do we center for oblique views of the esophagus?

A

2’’ from MSP toward side up (L) when done prone

34
Q

List the proper prep for the following exams.

  1. BASW
  2. UGI
  3. SBS
A
  1. No prep needed
  2. NPO since midnight
  3. NPO
35
Q

What position may better demonstrate hiatal hernias?

A

Trendelenburg

36
Q

If a patient is positioned in an upright AP projection describe where the barium and air will be.

A

Barium in the Pylorus

Air in the Fundus

37
Q

Explain what happens to the stomach if the patient is hypersthenic.

A

The stomach lays high, is elongated, is away from midline and more horizontal.

38
Q

What will the radiographer do in regard to the patient rotation when performing oblique stomach views for the hypersthenic patient?

A

The radiographer will oblique the patient more.
