Three-dimensional CT Colonography

Three-dimensional endoluminal CT colonography (virtual colonoscopy): comparison of three commercially available systems.

OBJECTIVE The purposes of this study were to directly compare 3D endoluminal volume rendering and navigational capabilities of three different CT colonography systems and to assess feasibility of 3D evaluation for primary polyp detection. MATERIALS AND METHODS Closely matched endoluminal images from three CT colonography software systems (Navigator, Vitrea 2, and V3D-Colon) and optical colono...

Three-dimensional virtual dissection at CT colonography: unraveling the colon to search for lesions.

Computed tomographic (CT) colonography is a promising noninvasive examination for colorectal cancer screening; however, the optimal interpretation strategy remains undecided. Virtual dissection is an innovative technique whereby the three-dimensional (3D) model of the colon is virtually unrolled, sliced open, and displayed as a flat 3D rendering of the mucosal surface, similar to a gross pathol...

CT colonography standards.

Computed tomography (CT) colonography is the established successor to the barium enema for the detection of colonic neoplasia due to superior performance and patient experience. Consequently, CT colonography is widely disseminated across Western populations and increasingly provided by both subspecialist and general radiologists alike. As a result, CT colonography is now part of the core traini...

Evolution of CT colonography REVIEW

Many public health organizations, including the American Cancer Society, recommend colorectal carcinoma screening for all average risk adults beginning at the age of 50 years. Colorectal cancers are known to develop from precursor adenomatous polyps that progress from small to large size and from dysplasia to cancer over the course of many years. Despite the potential for prevention, patient co...
