Following instrumental methods were used: CT colonoscopy, fibrocolonoscopy, irrigography-irrigoscopy, ultrasound research of colon. Computer Tomography researches was carried out on "General Electric" (USA) 16 layer CT scanner with 1.2 mm step by following phases: definition of research indication, preparation of intestine, insufflation, getting image, working on image and interpretation. In all cases intenstine was filled up with common air by manually method. According to 224 patients examination results in colon growing anomalies diagnostic CT colonoscopy responsivity is 98,0%, specificity 100%, diagnostic accuracy 98,2%, diverticulosis diagnostic 92,3%, 95,1%, 92,7%, and accordingly polyps in diagnostic: 87,3%, 85,6%, 85,9%.
