Large Intestine Contrast Studies Flashcards
List a reason why an air contrast BE study is preferred over a double contrast BE study.
Better visualization of mucosal lining and it will distended the bowel.
Barium is referred to as a –1– meaning that it will not ever totally mix and will not be absorbed into the body.
- Suspension
List three methods used for cleansing the bowel in preparation for a barium enema exam.
- Enema
- Dietary Restrictions
- Laxatives
Double contrast barium enema exams may be performed by using two different methods for filling the colon with air and barium. Describe the both.
- Single stage double contrast method in which the colon is selectively filled with barium and air at the same time.
- Two stage double contrast in which the colon is filled with the barium contrast, the pt elevates and returns to the radiographic table for insertion of air to finish the exam.
Explain the proper breathing method that should be explained to the patient that will assist them throughout the BE procedure.
Slow deep breathing. In through the nose out through the mouth.
The temperature of choice for barium preparation is –1–.
41 degrees F
The –1– position is used when the enema tip for a procedure.
Sims
The –1– method of filling the colon calls for filling the colon with barium, emptying, and filling with air.
Welin
The most anterior structure of the large intestines is the –1–.
Transverse Colon
The external opening of the large intestine is –1–.
Anus
The pouches of large intestine are –1–.
Hautra
When performing a BE exam, it is referred to as a –1–.
Retrograde
The –1– position will best demonstrate and open the hepatic flexure.
LPO
When a left lateral decubitis radiograph of an air contrast BE, the –1– will be filled with air.
ASCENDING COLON
The CR should be to the approximate level of –1– for a PA projection BE follow up radiograph.
Iliac crest
When performing an AP axial projection BE follow up radiograph, the CR should be –1– degrees –2–.
- 30-40 degrees
2. Cephalic
When performing an AP projection during an air BE study, air may appear in the –1– due to its position.
Transverse Colon
List three things that occur in order for something to be decubitus.
- Vertical IR
- Horizontal CR
- Recumbent patient
The most anterior part of the stomach is –1–.
Pylorus
Splenic Flexure
RPO
BA filled descending colon
Left lateral decub
BA filled transverse colon
PA
Rectosigmoid
AP axial
Hepatic Flexure
LPO
Air filled transverse colon
AP
Air filled descending colon
Right lateral decub
Rectum and distal sigmoid
Lateral
How much should patients be obliqued when performing the BE follow ups?
35-40 degrees
The costophrenic angle is at vertebral –1–.
L1-L2
What position will best demonstrate the duodenal loop?
Lateral
Why is it important that the entire colon be cleaned out prior to the BE exam?
So fecal matter doesn’t mimic pathological polyps or lesions.
What is proper kV to use when performing BE exam and why?
90 kG or higher because you’re trying to penetrate barium.
The CR should be directed to enter –1– for the AP axial projection of the colon.
2” below ASIS
When performing the PA axial projection of the colon, the CR should be angled –1– degrees –2– entering –3–.
- 30-40 degrees
- Caudal
- ASIS
When performing through left or right lateral projection for colon, the CR should perpendicular and directed to the level of –1–.
ASIS
What centering adjustment may need to be made when performing any projection for the colon in the upright positi.
May need to center down a little lower due to the colon moving lower in abdominopelvic cavity.
The for barium from ingestion to colonic filling –1–.
3-4 hrs
What is the general term given for a surgical procedure of an artificial opening into the intestine?
Enterostomy
Once the waste products of digestion have entered the colon, if too much water/fluid is absorbed by the body the resulting affect to the patient is the condition of –1–.
Constipation
