Advances in CT Colonography for Colorectal Cancer Screening and Diagnosis

CT colonography (CTC) is a validated colorectal cancer test that provides an additional minimally-invasive screening option which is likely to be preferred by some patients. Important examination prerequisites include adequate colonic cleansing and distention. Tagging of residual material aids in the differentiation of true polyps from stool. Low radiation dose technique should be employed rout...

CT colonography: A new technique for colorectal cancer screening

Although optical col on oscopy is the criterion standard for colorectal cancer screening, CT colonography is now accepted to be useful when screening averagerisk patients. Earlier studies that indicated poor sensitivity for CT colonography have now been largely refuted. Recent improvements in workstation design and advances that permit primary 3D viewing of images have increas ed screening accu...

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...

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 ...
