Paper Abstract

The purpose of this study was to perform CT colonography (CTC) without cathartic colon cleansing. Four groups of 3 patients were prepared the day before CTC with a dedicated low residue diet, a hydration control allowing 2 liters of fluid intake and barium as tagging agent. Four different barium regimens were investigated. Groups 1 and 3 ingested barium over 1 day at different concentrations and groups 2 and 4 over 2 days. The barium volume to drink the day before CTC was 750 ml in groups 1 and 2 and 50 ml in groups 3 and 4. The fluid, density measurements of the fecal residue and tagging efficacy were evaluated. All fecal residue with densities ≥ 150 H.U. was electronically labeled. Per segment a visual labeling score (0, 25, 50, 75, 100%) was performed. The fluid was evaluated according to its proportion to the maximum anteroposterior diameter of the colonic segment where it was detected. No significant differences in densities of tagged residue were detected. The visual labeling scores varied between 90 and 100% in all segments. There were 6 fluid levels: 5 covering < 10% and one covering 50% of the colonic lumen. The lowest density of the fluid was 360 H.U. In this preliminary study we could conclude that CTC without cathartic cleansing and with barium produced efficient labeling of fecal residue. The barium intake could be reduced to one day and to 50 ml.
