CT Colonography

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...

Synchronous Navigation for CT Colonography

We present a synchronous navigation module for CT colonography (CTC) reading. The need for such a system arises because most CTC protocols require a patient to be scanned in both supine and prone positions to increase sensitivity in detecting colonic polyps. However, existing clinical practices are limited to reading one scan at a time. Such limitation is due to the fact that building a referen...
