CT colonography is a modern examination method in the diagnostics of disease of the large intestine. Its advantage is a minimal invasiveness, correct pre-operative staging, the possibility of the examination of an intestine with stenotizing tumors after an unsuccessful colonoscopy, as well as detection of extracolonic findings. Using CT colonography as a screening method is discussed. A disadvantage is its expensiveness and a radiation risk. Necessary preconditions for a high-quality imaging are a quality multi-detector CT apparatus, sophisticated data-processing software, a carefully prepared patient and an educated radio-diagnostician. Authors explore file of 43 patients in view of classification, clinical relevance and effect on subsequent therapeutic plan in extracolonic findings, which are additive benefits of CT colonography as mentioned above.
