Purpose: The purpose of this study was to assess the feasibility of CT colonography (CTC) using the fecal tagging method in children and tagging performance. Methods: A total of 11 outpatient patients were subjected to this study. All patients underwent bowel preparation using amidotrizonic acid at a dose of 0.8±0.1ml/kg/day for three days prior to CTC. After colonic air insufflations, CT was scanned in both supine and prone position. In six colon segments and between different patients, the degree of fecal tagging was evaluated and graded in six point scale by two independent radiologists. Results: All studies were performed without any complications. All patients needed no sedatives. Tagging performance was "good" or "moderate" in 86% of evaluated residual segments. Conclusion: In conclusion, CTC with fecal tagging method is safe and feasible in children.
