• Better outline the colon and rectum

• Evaluate for colitis, bowel perforation, or rectal tumors

• Assess anorectal abscesses or fistulas

• Improve visualization in post-surgical cases or complex infections

6. What should you do before a CT Abdomen and Pelvis?

• Fasting: Don’t eat for at least 4–6 hours before the scan (especially if IV/oral contrast is used).

• Hydration: Drink plenty of water unless advised otherwise.
