Abstract
The purpose of this study was to evaluate the feasibility of single scan CT colonography (CTC) using polyethylene glycol electrolyte solution with contrast medium (PEG-C) bowel preparation in children. Seven patients suspected of colorectal elevated lesions were subjected to CTC. All patients underwent bowel preparation using polyethylene glycol electrolyte solution (PEG) at a dose of 32 ± 3 ml/kgBW before the day of CTC. The water-soluble contrast agent was given to the patients at a dose of 0.6 ± 0.1 ml/kgBW the next morning. After colonic air insufflation, the patient was scanned axially with a single run. After evaluation of multiplanar reformation images, 3-dimensional images (CT enema and virtual endoscopy image) were reconstructed. CT enema image was composed from air image and contrast-medium image. All studies were performed without complications. CTC showed the entire colon without blind spots in all patients with only single scan. In conclusion, the single scan CTC using PEG-C preparation is safe and less invasive compared to conventional CTC due to the shorter examination time and lower radiation dose.
