| Abstract |
In this thesis, CT colonography was investigated in a population at increased-risk for colorectal cancer. We focused on a limited bowel preparation for CT colonography with regard to image quality, diagnostic value and patient acceptance. Furthermore, performance characteristics of radiographers and of a computer aided diagnosis algorithm were evaluated in cathartic CT colonography. Finally, radiation doses that are currently used for CT colonography around the world were determined by means of a survey.
