Computer tomography colonography participation and yield in patients under surveillance for 6-9 mm polyps in a population-based screening trial [PDF]

, 2016
Purpose: Surveillance CT colonography (CTC) is a viable option for 6-9 mm polyps at CTC screening for colorectal cancer. We established participation and diagnostic yield of surveillance and determined overall yield of CTC screening. Material and methods:

Occult Dysplasia in a Localized Giant Pseudopolyp in Crohn’s Colitis: A Case Report

Canadian Journal of Gastroenterology, 2009
Localized giant pseudopolyposis of the colon (pseudopolyp larger than 1.5 cm in size) is a rare complication of inflammatory bowel disease. There is one report of an occult carcinoma within such a lesion, and no reports of sole dysplasia.

Colorectal cancer screening for average-risk North Americans: an economic evaluation. [PDF]

PLoS Medicine, 2010
BACKGROUND: Colorectal cancer (CRC) fulfills the World Health Organization criteria for mass screening, but screening uptake is low in most countries. CRC screening is resource intensive, and it is unclear if an optimal strategy exists.

A Clinical Decision Support Framework for Incremental Polyps Classification in Virtual Colonoscopy

Algorithms, 2010
We present in this paper a novel dynamic learning method for classifying polyp candidate detections in Computed Tomographic Colonography (CTC) using an adaptation of the Least Square Support Vector Machine (LS-SVM).

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.
