Virtual colonoscopy, or CT colonography, is a rapidly evolving technique for the detection of tumoral lesions in the colon. It is now accepted by the American Cancer Society as a valuable screening tool for both colorectal cancer and its adenomatous precursor. Virtual colonoscopy requires state-of-the-art technique with rigorous preparation, colonic distension, and optimization of scanning parameters. Dedicated reading, analysis, and reporting of the data sets are mandatory. With contributions from a number of 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; the importance of computer-aided diagnosis is also discussed. In this second edition the text has been updated with the latest study results and developments in technology and new illustrations have been included. This book will be invaluable to every radiologist seeking information on how to perform the exciting technique of virtual colonoscopy.
gAs barium enema rapidly gives way to the era of virtual colonoscopy (VC), increasing numbers of radiologists and gastroenterologists need a guide to navigate this transition. The second edition of eVirtual Colonoscopy: A Practical Guidef has arrived to fulfil this need. c I would highly recommend this practical and informative book to anyone interested in virtual colonoscopy. I would particularly recommend it for radiologists making the transition from barium to VC, radiographers and perhaps most of all, sceptical colonoscopists.h

geThe book offers a very comprehensive overview of all aspects and issues of [computed tomographic] CT colonography with a focus on how to perform practically this examination.f c I found the book to be well organized and written clearly and succinctly. c book is intended to be ea guide for both the beginner and the experienced CT colonographer. It fulfills its purpose and is an excellent resource for radiologists and radiology residents who are involved in performing and interpreting virtual colonoscopy.h
