Contribution of CT colonography to clinical practice

CT Colonography: A Guide for Clinical Practice

Computerised tomography (CT) colonography has been a rapidly evolving subject over the last few years due to a combination of clinical need and technological advances. The technique has moved from primarily a research tool to a commonly accepted examination in the clinical diagnostic armoury. Its position in the diagnostic hierarchy for colonic disorders is continuing to evolve. Colorectal carc...

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...

External Clinical Validation of Prone and Supine CT Colonography Registration

This paper provides an external validation of a prone-supine registration algorithm for CT colonography (CTC). A validation sample of 49 patient cases with 66 polyps (6 to 30mm) was selected from a publicly available, anonymized CTC archive. To enhance generalizability, no case was excluded due to poor preparation or inadequate distension. Corresponding prone and supine polyp coordinates were r...

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...
