CT Colonography for Radiographers
Description
This book explains every aspect of the role of radiographers in performing CT colonography (CTC) and interpreting CTC images with the aim of enabling radiographers to extend the scope of their practice. It provides all the information required with respect to procurement of informed consent, principles of CT and radiation dose, patient preparation and positioning, the use of contrast media, the performance of diagnostic and screening CTC studies, and the interpretation and reporting of images. A wide range of CTC findings are described and depicted, covering normal anatomy, artifacts, hemorrhoids, polyps, colon cancer, diverticular disease, lipomas, and extracolonic structures. In addition, a chapter focusing on self-assessment of image interpretation will aid learning. The rising number of CTC studies for colon disorders is adding to an already burdened radiology workload. To reduce this workload, radiographers will increasingly be given responsibility to carry out CTC examinationsand this book will provide the support that they need in order to perform CTC studies to the standard required.

"This claims to be the first textbook on CT colonography (CTC) performance and image interpretation written for radiographers. . Throughout there are plentiful illustrations of good quality. . this book achieves its aim admirably. . it is also a most useful text for radiologists who are starting out in CTC or for radiologists already experienced in the technique who wish to keep their skill up to the mark." (Dr. Nick Reading, RAD Magazine, May, 2017)"This book contains a wealth of information for those starting out in providing a CTC service in their hospitals and departments and also for those practitioners who require a workbench manual. The book is written in a clear and concise manner with a good glossary and index. . Dr Bortz and colleagues have written an excellent book in this evolving imaging technique that radiographers, radiologists, family physicians and gastroenterologists will find useful and practical." (Peter Corr, The South African Radiographer, Vol. 55 (1), May, 2017)
