Patient Preparation

Abstract

As is the case with many radiological examinations, computer tomography (CT) colonography (CTC) requires adequate preparation of the patient prior to imaging to achieve its full diagnostic potential. Properly performed, the preparatory steps of CTC contribute to high sensitivity for detection of polyps and can be obtained with a minimum of patient discomfort. In this chapter, we will focus on two topics central to achieving a high-quality exam: patient education and bowel preparation. Our review will include methods currently employed to achieve these ends, as well as a discussion of research aimed at improving them. Throughout this chapter, we will emphasize practical aspects of patient preparation that can improve both patient comfort and the quality of colonography images.
