Abstract

Colorectal carcinoma is the 3rd commonest malignancy and 2nd cause of mortality due to cancer. It is the result of a multiyear, multistep transformation of an asymptomatic adenomatous polyp to a symptomatic invasive carcinoma. Optical colonoscopy (OC) and laboratory testing have been traditionally used in colorectal cancer (CRC) screening, diagnosis, and follow-up. Since its introduction in 1994 computer tomography colonoscopy (CTC) has gradually been enlisted in CRC screening and diagnosis methods functioning either as an alternative or a first-choice examination. This review focuses on CTC development, current indications, methodology, image acquisition followed by case examples from our department, data reporting, and future directions.
