A note on feature selection for polyp detection in CT colonography [PDF]

, 2006
In this paper we describe a computer aided detection (CAD) algorithm for robust detection of polyps in computed tomography (CT) colonography. The devised algorithm identifies suspicious polyp candidate surfaces using the surface normal intersection ...

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.

Retrospective analysis of computed tomographic colonography in a rural hospital [PDF]

Journal of Medical Imaging and Radiation Oncology, 2017
AbstractIntroductionThe aims of this study were to investigate the diagnostic performance of computed tomography colonography (CTC) performed in a rural secondary hospital, and to describe the local pattern of CTC service provision.MethodA single site, retrospective observational analysis was conducted for all patients undergoing CTC during the 12 ...

Computed tomographic colonography for symptomatic patients: the diminutive polyp dilemma

, 2022
Background: Computed tomographic colonography (CTC) is sensitive to polyp detection but is considered inaccurate for measuring diminutive polyps (6 mm, cases were categorized as either 'diminutive' (largest polyp 0.05) in mean age (73 vs.

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
