Q

What are some suggestions to a patient for quicker emptying/ passing of barium through the bowel during a SBS?

A
  1. The patient can walk around the department.
  2. Talk to patient about food.
  3. Use the “F” spoon or the paddle with the balloon to help barium pass through the small bowel.
  4. The upright position will increase the functioning time of duodenal filling and emptying.

Q

Explain why a higher kV is necessary for demonstration of the alimentary canal?

A

Area being x-rayed is thick and an increase in the penetration ability of beam to reach the desired structures is needed. Also trying to penetrate/image structures that are filled with barium.

  2. Carbonated Beverage
  3. Poke holes in the straw the patient is drinking from
17
Q

The CR should be directed to this vertebral level for stomach radiography? –1–
This is at the bony landmark of the –2–.

A
  1. L1-L2

2. Cosaphrenic Angle

18
Q

What body habitus requires a greater degree of obliquity for stomach radiography?

A

19
Q

How will the stomach be demonstrated or seen when the LAO position is performed?

A

Elongated

20
Q

List 2 things the Valsalva Maneuver may demonstrate during a BASW or UGI?

A
  1. Esophagus Varacies

2. GERD

21
Q

What muscle structure allows food stuff or barium to pass into the large intestines and indicates the completion of a SBS?

A

Ileocecal Valve

22
Q

Briefly explain your instructions to a patient when you perform BASW f/u radiographs to ensure that the entire esophagus will be filled with barium?

A

Take a drink, hold it in your mouth, now swallow, keep drinking, keep drinking. On the second Keep Drinking, get on rotor-on the 3rd Keep Drinking, expose so the esophagus is filled with barium when exposing.

23
Q

What is the purpose of air/gas being used during stomach studies?

A

Mucosal lining will be better visualized

24
Q

If a patient is examined in the upright position air will be in the –1– of the stomach.

A

Fundus

Q

What is the term for examination of the small intestine by direct injection of barium under fluoroscopic guidance?

A

Enteroclysis Procedure

LPO

27
Q

Barium will be in the –1– for the above position (AP LPO).

A

Fundus

28
Q

What should the proper respirations be for examination of the stomach, small bowel, or general abdominal cavity?

A

Suspend on Exhalation

29
Q

Explain the anterior/posterior centering when performing a lateral stomach.

A

CR centered midway between the MCP and the anterior surface of the abdominal cavity.

30
Q

What lateral of the stomach will cause it to empty it quicker?

A

right
