25
Under normal circumstances the stomach will empty in _____
2-3 hours
26
What stomach position best demonstrates the duodenal bulb
PA oblique RAO or LPO
27
What are some suggestions to make for quicker emptying/passing of barium through the bowel during a SBS?
- talk about food - walk - lay on right side
28
What is the best position/projection to demonstrate the esophagus without superimposition of the heart or spine?
RAO
29
What is the degree of obliquity for stomach radiography?
40-70
30
What is the degree of obliquity or esophagus radiograph and why?
35-40 because it gets it away from the spine
31
Explain why a higherLV is necessary for demonstration of the alimentary canal...
B/c barium has a higher atomic number and it is harder to penetrate
32
If a pt is lying supine, what portion of the stomach will contain barium?
Fundus
33
The top of the IR should be placed at __1__ or BASW radiograph. This correlates to the CR being directed to what vertebral level? __2__
1. EAM | 2. T5-T6
34
When barium studies of the upper intestinal tract are preformed, what are three ways that air may be introduced?
1. Gas crystals 2. Carbonated drink 3. Drinking barium via straw
35
1. The CR should be directed at this vertebral level for a stomach radiograph? 2. This is at the bony landmark of the ____
1. L1-L2 | 2. Costal angle
36
What body habitus requires a GREATER degree of obliquity for a stomach radiograph?
Hypersthenic
37
How will the stomach be demonstrated or seen when the LAO position is performed?
Elongated
38
List 2 things the Valsalva Maneuver may demonstrate during a BASW or UGI
1. Esophageal varicies | 2. GERD
39
What muscle structure allows food stuff or barium to pass into the large intestine and indicates the completion of a SBS?
Ileocecal valve
40
What is the purpose of air/gas being used during stomach studies?
Expand rugea
41
If a pt is examined in the upright position air will be in the
Pyloris
42
What is the term or examination of the small intestine by direct injection of barium under fluoroscopic guidance?
Enterocalysis
43
1. A pt is radiographed using AP projection, oblique position and the duodenal bulb is well demonstrated. Name specific position. 2. Barium will be in the ___ for the above position
1. LPO | 2. Fundus
44
What should the power respirations be for examination of the stomach, small bowel, or general abdominal cavity?
Suspend on exhalation
45
Explain the anterior/posterior centering when performing a lateral stomach?
Centering to L1-L2 2" from MCP bisect mid coronal plane and anterior border of pt
46
Failure of the smooth muscle of the alimentary canal to relax
Achalasia
47
Inflammation of the appendix
Appendicitis
48
Peptic ulcer of the lower esophagus, often with stricture
Barrett's Esophagus
49
Digestion and absorption takes place in this portion of the alimentary canal
Small Intestines
50
Which position will demonstrate the entire duodenal loop?
Right lateral
51
Which projection, PA or AP is PREFERRED when demonstrating the small intestines?
PA
52
What is another name for the LES
Cardiac sphincter
53
Why would barium not be he contrast of choice if a pt has a suspected perforation?
Body cannot absorb barium, if it is leaked into peritoneum it could be toxic
54
What position will best demonstrate the duodenal bulb?
RAO
55
The structure that allows passage of food/barium from the small intestines into the large intestines called the ______
Ileocecal valve
56
What type of contrast should be used if there is a suspected perforation in the digestive tract and why?
Iodine, because body can absorb it if it leaks into the peritoneum due to perforation
57
What is meant by the term "full column" or single contrast study of the esophagus?
Entire esophagus filled with barium/using BA only (no gas)
58
List the proper prep for the following exams: 1. BASW 2. UGI 3. SBS
1. None 2. NPO 3. NPO
59
What position may better demonstrate hiatal hernias?
Trendelenburg
60
If a pt is positioned in an upright AP projection describe where the barium and air will be?
Barium-pylorus | Air-fundus
61
Which section of the small bowel is the shortest
Duodenum
62
Name three organs with ducts that enter/empty into the small bowel
Liver, gallbladder, pancreas
63
What organ is part of both the respiratory and digestive systems?
Pharynx
