RESUMO
The colonic transit of an indium-111 enteric coated capsule was imaged with a gamma camera over a period of 3 days. The geometric centre of activity in the colon was calculated from regions drawn over four segments of the colon, plus a fifth segment as the estimated passed stool activity. Fifteen healthy subjects were scanned and the results analysed. The images were analysed by two observers to assess reproducibility of the geometric centre quantitative index (correlation, r = 0.985). In conclusion, although it can be difficult to identify the anatomical segments of the colon from the gamma camera images, by following a protocol with clear guidelines for ROI placement, good inter-observer reproducibility can be obtained.
