Q

Double contrast barium enema exams may be performed by using two different methods for filling the colon with air and barium. Describe the both.

A
  1. Single stage double contrast method in which the colon is selectively filled with barium and air at the same time.
  2. 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.

29
Q

A

L1-L2

30
Q

What position will best demonstrate the duodenal loop?

A

Lateral

31
Q

Why is it important that the entire colon be cleaned out prior to the BE exam?

A

So fecal matter doesn’t mimic pathological polyps or lesions.

32
Q

What is proper kV to use when performing BE exam and why?

A

90 kG or higher because you’re trying to penetrate barium.

33
Q

The CR should be directed to enter –1– for the AP axial projection of the colon.

A

2” below ASIS

34
Q

When performing the PA axial projection of the colon, the CR should be angled –1– degrees –2– entering –3–.

A
  1. 30-40 degrees
  2. Caudal
  3. ASIS

Q

When performing through left or right lateral projection for colon, the CR should perpendicular and directed to the level of –1–.

A

ASIS

36
Q

What centering adjustment may need to be made when performing any projection for the colon in the upright positi.

A

May need to center down a little lower due to the colon moving lower in abdominopelvic cavity.

37
Q

The for barium from ingestion to colonic filling –1–.

A

3-4 hrs

38
Q

What is the general term given for a surgical procedure of an artificial opening into the intestine?
