Computed tomographic colonography: clinical value

Abdominal Imaging, 2007
Computed tomographic colonography (CTC) has the potential to reliably detect polyps in the colon. Its clinical value is accepted for several indications. The main target is screening asymptomatic people for colorectal cancer (CRC). As in large multi-centre trials controversial results were obtained, acceptance of this indication on a large scale is ...

Computed tomographic colonography for colorectal screening

Endoscopy, 2007
Computed tomographic colonography (CTC) is a specialized computed tomographic examination that has been optimized for the detection of colorectal polyps. The technology has undergone major advances in recent years and there is emerging consensus that state-of-the-art CTC results in performance characteristics comparable to those of optical colonoscopy ...

Meta-Analysis: Computed Tomographic Colonography

Annals of Internal Medicine, 2005
Computed tomographic (CT) colonography, also called virtual colonoscopy, is an evolving technology under evaluation as a new method of screening for colorectal cancer. However, its performance as a test has varied widely across studies, and the reasons for these discrepancies are poorly defined.To systematically review the test performance of CT ...

Ileocecal valve imaging on computed tomographic colonography

Abdominal Imaging, 2004
The aim of our study was to describe the visualization, normal anatomy, and variations of the ileocecal valve with computed tomographic (CT) colonography to provide information about its optimal imaging.We analyzed data in two- and three-dimensional rendering mode in 71 consecutive patients who underwent routine CT colonoscopy followed by conventional ...

Computed tomographic colonography

Current Opinion in Gastroenterology, 2009
Computed tomographic colonography is a new and noninvasive method to evaluate the colon. The goal of this review is to discuss the latest data and define outstanding issues related to computed tomographic colonography.Computed tomographic colonography is gaining momentum as a potential primary colon cancer screening method in the USA.

Computed tomographic colonography: comparison of two workstations

Acta Radiologica, 2005
Purpose: To compare two commercially available computed tomography (CT) colonography systems with respect to interobserver variability, the influence of level of expertise, and the gradual reduction of reviewing time for each system. Material and Methods: Two residents and two radiologists using Siemens CTAPP Colography software and ...

Computed tomographic colonography.

Acta gastro-enterologica Belgica, 2005
Computed tomographic colonography, also called virtual colonoscopy, is an evolving technology under evaluation as a new method of screening for colorectal cancer. However, its performance as a test has varied widely across studies, and the reasons for these discrepancies are poorly defined.

Colon Imaging: Computed Tomographic Colonography

Clinical Gastroenterology and Hepatology, 2005
Computed tomographic colonography (CTC, virtual colonoscopy) is an attractive modality with which to image the colon. Many different techniques are available; moreover, during the last several years, advances in hardware and software have been remarkable.

Computed Tomographic Colonography: Ready for Prime Time?

Gastroenterology Clinics of North America, 2010
Computed tomographic (CT) colonography is a noninvasive method to evaluate the colon and has received considerable attention in the last decade as a colon-imaging tool. The technique has also been proposed as a potential primary colon cancer-screening method in the United States. The accuracy of the technique for the detection of large lesions seems to

Computer-aided marginal artery detection on computed tomographic colonography

SPIE Proceedings, 2012
Computed tomographic colonography (CTC) is a minimally invasive technique for colonic polyps and cancer screening. The marginal artery of the colon, also known as the marginal artery of Drummond, is the blood vessel that connects the inferior mesenteric artery with the superior mesenteric artery.
