Computed tomographic (CT) colonography continues to evolve rapidly. Advances in
scanning and display technologies, encouraging performance data, and increased …

Background: Computed tomographic (CT) colonography, also called virtual colonoscopy, is
an evolving technology under evaluation as a new method of screening for colorectal …

Background We evaluated the performance characteristics of computed tomographic (CT)
virtual colonoscopy for the detection of colorectal neoplasia in an average-risk screening …

Purpose: To retrospectively determine which of several computed tomographic (CT)
colonography–based polyp measurements is most compatible with the linear measurement …

We present an approach to the detection of tumors in colonoscopic video. It is based on a
new color feature extraction scheme to represent the different regions in the frame …

Background Colonic polyps are more likely to be cancerous, especially those with large
diameter, large number and atypical hyperplasia. If colonic polyps cannot be treated in early …

We have developed a three-dimensional (3-D) computer-aided diagnosis scheme for
automated detection of colonic polyps in computed tomography (CT) colonographic data …

Literature review indicates high levels of error within radiology. The aetiology of radiological
error is multi-factorial. While individuals have a duty to progressively improve their …

PURPOSE: To evaluate the accuracy of contrast material–enhanced multi–detector row
computed tomographic (CT) colonography for preoperative staging of colorectal cancer …

OBJECTIVES: The aim of this study was to determine patient pre-examination expectations
and postexamination appraisals for CT colonography, conventional colonoscopy and bowel …
