Abstract
Objective
Performing computed tomography (CT) colonography, we compared different reconstruction
modi for the detection of colorectal polyps.
Methods
The CT data of 48 patients using 16-slice helical CT were analysed in axial slices,
virtual-endoscopy and colon-dissection modus.
Results
The sensitivity (specificity) for the detection of colonic polyps was 94% (80%) if
using “colonic-dissection” tool and 89% (80%) if using “virtual-endoscopy” tool. The
difference between the virtual endoscopy and colon dissection, considering polyps
up to 4.9 mm, was significant.
Conclusions
Reconstruction software colon dissection improves the sensitivity of CT colonography.
