Consensus on current clinical practice of virtual colonoscopy.

OBJECTIVE The purpose of our study was to determine the current opinions regarding the performance, interpretation, reporting, and clinical role of virtual colonoscopy among a group of selected experts to develop a consensus statement. MATERIALS AND METHODS A questionnaire was sent to 33 selected experts in virtual colonoscopy. Responses were tabulated and results were used to develop a conse...

A Hybrid 3D Colon Segmentation Method Using Modified Geometric Deformable Models

Introduction: Nowadays virtual colonoscopy has become a reliable and efficient method of detecting primary stages of colon cancer such as polyp detection. One of the most important and crucial stages of virtual colonoscopy is colon segmentation because an incorrect segmentation may lead to a misdiagnosis.  Materials and Methods: In this work, a hybrid method based on Geometric Deformable Models...

COMPUTED TOMOGRAPHIC COLONOGRAPHY (VIRTUAL COLONOSCOPY) FOR SCREENING OF COLORECTAL CANCER INTRODUCTION The California Technology Assessment Forum is requested to review the scientific evidence for the use of computed Tomographic Colonography (virtual colonoscopy) for screening of colorectal cancer

Virtual vs. optical colonoscopy in symptomatic gastroenterology out-patients: the case for virtual imaging followed by targeted diagnostic or therapeutic colonoscopy.

AIM To compare virtual colonoscopy with optical colonoscopy findings in symptomatic patients. BACKGROUND Computer tomographic colonography is an alternative to optical colonoscopy. Studies have shown that two-dimensional computer tomographic colonography does not have sufficient sensitivity. Three-dimensional computerized tomographic virtual colonoscopy compares well with optical colonoscopy ...
