Which item is commonly part of CT patient preparation?

• A. Fasting for 24 hours prior to scan
• B. No Gown Change Required
• C. Oral Contrast Media Given Prior to Scan (abdomen/pelvis)
• D. No Consent Required

Answer: (C)

The main idea being tested is how CT prep supports accurate diagnosis, especially for the abdomen and pelvis. Giving oral contrast before the scan is a common preparation step because the iodinated liquid coats the lining of the gastrointestinal tract. This makes the bowel lumen stand out from surrounding tissues, helping to clearly see walls, lesions, inflammation, or other abnormalities. It also helps distinguish intraluminal contents from surrounding structures, improving overall image interpretation for abdominal/pelvic CT. In contrast, fasting for 24 hours isn’t a typical universal requirement for CT prep and isn’t standard practice for most abdomen/pelvis scans. A gown change is often used to reduce artifacts and ensure safety, so saying no gown change is required isn’t accurate. And consent is normally obtained before imaging, so saying no consent is required isn’t correct.
