Review of Computed Tomographic Colonography from a Surgeon’s Perspective

Journal of Gastrointestinal and Liver Diseases, 2015
Abstract New research has addressed many of the early concerns of Computed Tomographic colonography (CTC) and these studies are now beginning to shape clinical practices. A review of the literature demonstrates that the sensitivity of CTC in screening for large polyps (≥ 1cm) or cancers in the large intestine is as high as that of conventional optical

Patients & healthcare professionals values regarding true and false-positive diagnosis when colorectal cancer screening by CT colonography : discrete choice experiment [PDF]

, 2013
PURPOSE: To establish the relative weighting given by patients and healthcare professionals to gains in diagnostic sensitivity versus loss of specificity when using CT colonography (CTC) for colorectal cancer screening.

Computed tomographic colonography in the diagnosis of colorectal cancer

British Journal of Surgery, 2010
AbstractBackgroundThis study aimed to determine the sensitivity of computed tomographic colonography (CTC) in diagnosing colorectal cancer and to explore the reasons why these cancers are missed on CTC.MethodsPatients who underwent CTC in the 56-month period from 1 January 2004 to 1 September 2008, and all cases of colorectal cancer recorded in the ...

ORIGINAL ARTICLE: Will An Additional Observer Enhance Adenoma Detection During Colonoscopy? [PDF]

, 2012
Background: Due to varied level of experience, the detection rate of adenoma on colonoscopy is different. In presence of both fellows and attending the incidence rates of adenoma are shown to increase in a small study reported by Rogart et al [4].

Texture analysis of CT colonography to develop a novel imaging biomarker for the management of colorectal cancer

Annals of Gastroenterological Surgery
Background Recent studies have focused on evaluating the biomarker value of textural features in radiological images. Our study investigated whether or not a texture analysis of computed tomographic colonography (CTC) images could be a novel biomarker ...
