Q

What is the centering point for the UGI and the SBFT Combination?

A

Centered at (L2) for stomach and proximal Small Bowel

20
Q

For the oral method SBFT, how often are images taken?

A

Every 30 minutes until barium reaches the terminal ileum (usually 2 hours)

21
Q

What does SBFT stand for?

A

Small bowel follow-through

22
Q

What are the three views for the Upper GI & SBFT Combination?

A
  1. Prone
  2. Supine
  3. LPO
23
Q

What is the purpose of doing prone imaging for the Upper GI & SBFT Combination proceedure?

A

-Compress the abdominal contents
-Provides radiation protection,

24
Q

What is the pupose of doing supine imaging for the Upper GI & SBFT Combination proceedure?

A

-Prevents compression of overlapping loops of intestine

25
Q

What does supine imaging demonstrate for the Upper GI & SBFT Combination proceedure?

A

Demonstrates superior and lateral shift of barium-filled stomach

26
Q

How much should the patient be obliqued for the LPO imaging for the Upper GI & SBFT Combination proceedure?

A

Oblique view to demo the stomach and 1st part of duodenum

27
Q

What is the the centering point for images taken up to 15 minutes after contrast injection for the Upper GI & SBFT Combination proceedure?

A

L2

28
Q

What is the the centering point for images taken after 15 minutes after contrast injection for the Upper GI & SBFT Combination proceedure?

A

At the illiac crest

29
Q

What kVp is used for the Upper GI & SBFT Combination proceedure?

A

125kVp

30
Q

What body position is used for imaging of the Upper GI & SBFT Combination proceedure? Why?
