T/F
For imaging of the small bowel, you should always include pubic symphysis
True
What are the contraindications to small bowel imaging?
- Complete obstruction
- Suspected perforation
- Pre-surgical patients;
- Concern regarding fecal impaction
What is the patient prep prior to small bowel imaging for the UGI or SBFT proceedures?
- Low residue diet 2-3 days prior to exam
- NPO 8-12 hours before the exam
- No smoking or chewing gum
- Remove all clothing, put on hospital gown
- Possible cleansing enema before
If there was a perforation or obstruction, and the patient needed small bowel imaging, what type of contrast would we give them?
Water-soluble iodinated contrast

30%-50% w/v
What can be done if the patient’s peristalsis is very slow in small bowel imaging?
-Have them move around between images
-Give them gastric stimulants
T/F
You can give negative contrast for the small bowel series when requested.
True
What is the proceedure step by step for the Upper GI & SBFT Combination proceedure?

What is the purpose of doing prone imaging for the Upper GI & SBFT Combination proceedure?
-Compress the abdominal contents
-Provides radiation protection,
What is the pupose of doing supine imaging for the Upper GI & SBFT Combination proceedure?
