Which statement is true about CT colonography's handling of stool artifacts?

• A. Stool artifacts should be ignored as they do not affect interpretation.
• B. Polyp findings should be assumed if stool is present.
• C. Describe filling defects and layering stool; emphasize that stool can mimic polyps and recommend cleansing or repeat imaging if uncertainty persists.
• D. Recommend immediate surgical consultation for any stool artifact.

Answer: (C)

In CT colonography, stool artifacts can masquerade as polyps or obscure true lesions, so the report should actively address them. The best approach is to describe how the stool appears—mention any filling defects and layering of stool—and emphasize that stool can mimic polyps. Then guide next steps: recommend enhanced bowel cleansing or repeat imaging if uncertainty remains, to differentiate stool from real polyps. This balances accurate interpretation with patient management. Ignoring stool artifacts is risky because it can lead to false interpretations. Assuming polyps are present simply because stool is seen is inappropriate. Recommending immediate surgical consultation for a stool artifact is excessive; the appropriate response is to optimize preparation or repeat imaging to clarify findings.
