Abstract: 
The diagnostic value of colonoscopy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>virtual colonoscopy versus colon oscopy was compared in detection of colorectal neoplasia. colonoscopy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>virtual colonoscopy was performed on 29 patients with suspected colorectal diseases, results were compared with colonoscopy for each case. colonoscopy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>virtual colonoscopy was successfully performed on each patient. All patients tolerated colonoscopy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>virtual colonoscopy well, had no complications. All colorectal malignance were identified both by colonoscopy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>virtual colonoscopy and colonoscopy. Twenty-five polyps were detected with colonoscopy, whereas only 16 polyps were defined by colonoscopy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>virtual colonoscopy. Detection rates of polyps greater than 1.0 cm, between 0.5-0.9 cm and less than 0.5 cm in size were 90%, 62.5% and 28.6% respectively. colonoscopy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>virtual colonoscopy is fast, minimally invasive and well tolerated. This technique is a valuable clinical method in diagnosis of colorectal malignance and polyps larger than 0.5 cm in size.
