Computed tomographic colonography compared with colonoscopy or barium enema for diagnosis of colorectal cancer in older symptomatic patients: two multicentre randomised trials with economic evaluation (the SIGGAR trials)

Health Technology Assessment, 2015
Background: Computed tomographic colonography (CTC) is a relatively new diagnostic test that may be superior to existing alternatives to investigate the large bowel.

Colon centreline calculation for CT colonography using optimised 3D opological thinning [PDF]

, 2002
CT colonography is an emerging technique for colorectal cancer screening. This technique facilitates noninvasive imaging of the colon interior by generating virtual reality models of the colon lumen.

Colorectal Laterally Spreading Tumors by Computed Tomographic Colonography

International Journal of Molecular Sciences, 2013
To date, few reports focused primarily on detecting colorectal laterally spreading tumors (LSTs) have been published. The aim of this study was to determine the visibility of LSTs on computed tomographic colonography (CTC) compared with that on colonoscopy as a standard.

Association between diverticulosis and colonic neoplastic lesions in individuals with a positive faecal immunochemical test [PDF]

, 2017
Background The association between diverticulosis and colonic neoplastic lesions has been suggested, but data in literature are conflicting. This study aimed to investigate such a relationship in patients participating in a colorectal cancer screening ...

Accuracy of CT Colonography for Detection of Large Adenomas and Cancers [PDF]

, 2008
Background Computed tomographic (CT) colonography is a noninvasive option in screening for colorectal cancer. However, its accuracy as a screening tool in asymptomatic adults has not been well defined.

Extracolonic findings of computed tomographic colonography in Koreans

World Journal of Gastroenterology, 2009
To determine the frequency and characteristics of extracolonic lesions detected using computed tomographic (CT) colonography.The significance of extracolonic lesions was classified as high, intermediate, or low. Medical records were reviewed to establish whether further investigations were carried out pertaining to the extracolonic lesions that were ...
