Virtual Colonoscopy : A Practical Guide
Virtual colonoscopy, or CT colonography, is a novel and rapidly evolving technique for the detection of tumoral lesions in the colon. It promises to be of great value as a screening tool for both colorectal cancer and its adenomatous precursor. Virtual colonoscopy requires rigorous preparation, colonic distension, and optimization of scanning parameters. Dedicated reading, analysis, and reporting of the data sets are mandatory. With contributions from several leaders in the field, this book addresses all the important issues relating to virtual colonoscopy. There is a particular focus on practical aspects: how to start virtual colonoscopy in your department, the regular preparation, the importance of fecal tagging, how to reduce the preparation, how to obtain optimal colonic distension, and the correct scanning parameters. Imaging characteristics and pitfalls are considered in detail, with an extensive pictorial review of difficult lesions, and the importance of computer-aided diagnosis is discussed.
Fundamentals of Virtual Colonoscopy
Virtual colonoscopy is a rapidly developing technique that can be performed in an outpatient setting without sedation. It promises to be safer and less intrusive than conventional diagnostic tests for colon cancer and is attractive to patients. Despite the attention that virtual colonoscopy has received among medical professionals, many lack an understanding of the basics of this cutting-edge procedure. Renowned radiologist Abraham Dachman, MD, and a distinguished group of international contributors have prepared a fundamentals book that fills this void. This practical handbook fully explains the essentials of this state-of-the-art technique to radiologists, gastroenterologists, radiology residents, and technologists. Major concepts are reinforced by clear, true-to-life illustrations. Readers will find that the practical design and current content of this guide make it an essential introduction to CT colonography.
