Question 2: Which is the ideal way to order a CT to see an intra-abdominal abscess? What findings are you looking for?
View answer
Answer 2:

A CT scan with both oral and IV contrast would be preferred. Oral contrast helps differentiate structures from within and outside of the intestine. It may also help reveal the presence of a fistula or other disruption of the bowel wall. IV contrast may enhance the abscess by concentrating the contrast material within the abscess wall. In a study without contrast such as this, fat-stranding around around the abscess is a key finding.
