Performance and Interpretation of CTC



It has been almost 30 years since Coin proposed that computed tomography (CT) scanning had the potential to be used as a screening tool for the detection of colonic polyps [1]. Yet it was not until 1994 that Vining and coworkers were able to employ the new technology of spiral/helical CT and modern computer graphics, catalyzing extensive research and clinical efforts that molded the field that we now call CT colonography (CTC) or “virtual colonoscopy.” [2] Owing to these efforts, reasonable consensus now exists on the optimal means by which to prepare the patient, acquire the CT data, and interpret the resulting images, though some healthy debates do persist. The goal of this chapter is to describe these technical factors in CTC and to give the reader a perspective on current techniques and alternatives. We review the best evidence for current practices and recommendations. With this information, we hope the reader will have a thorough understanding of what is required to set up a high-quality clinical operation for performance of CTC.
