CT colonography; latest indications, methodology, and case examples

Emmanouil Siderakis, Myrsini Stasinopoulou, Georgia Economou, Efthimios Andriotis


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.
