Colonic Distention at Screening CT Colonography: Role of Spasmolytic Agents and Body Habitus

CT colonography and colorectal screening.

Role of CT Colonography in Colonic Lesions and Its Correlation with Conventional Colonoscopic Findings.

BACKGROUND Preoperative evaluation in patients with colorectal carcinoma is essential for a correct therapeutic plan. Conventional colonoscopy has certain limitations including its inability to detect synchronous lesions in case of distal obstructive mass and inaccurate tumour localization. CT colonography combines cross sectional imaging with virtual colonoscopic images and offers a comprehens...

Screening CT colonography: how I do it.

OBJECTIVE The purpose of this article is to detail an approach to CT colonographic screening that has evolved at one institution. CONCLUSION CT colonography is a rapidly advancing technology that has great potential for addressing a deadly but preventable disease-colorectal carcinoma. CT colonography is ideally suited for widespread screening of asymptomatic adults and has become an integral ...

CT colonography screening: ready for prime time?

Every year more than one million new patients are diagnosed with colon cancer worldwide. Although multiple prospective randomized trials and observational studies have demonstrated that mortality from colon cancer can be reduced with screening and removal of adenomatous polyps, compliance with screening guidelines remains low. Recent CT colonography (CTC) trials have shown that CTC is capable o...

Colonic polyps: complementary role of computer-aided detection in CT colonography.

PURPOSE To apply a computer-aided detection (CAD) algorithm to supine and prone multisection helical computed tomographic (CT) colonographic images to confirm if there is any added benefit provided by CAD over that of standard clinical interpretation. MATERIALS AND METHODS CT colonography (with patients in both supine and prone positions) was performed with a multisection helical CT scanner i...
