Comparison of Radiologists' confidence in excluding significant colorectal neoplasia with multidetector-row CT colonography compared with double contrast barium enema.
By Taylor et al
"The aim of this study was to compare the confidence of experienced radiologists in excluding colonic neoplasia with CT colonography (CTC) compared with barium enema. Radiologists stated they had confidently excluded a significant lesion in 314 (71%) and 382 (86%) of 444 segments with barium enema and CTC, respectively. Confidence was significantly higher with CTC in the in the descending and ascending colon and caecum.Confidence in excluding polyps 6 mm or larger is significantly greater with CT colonography particularly in the proximal colon."
