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 examinations and this book will provide the support that they need in order to perform CTC studies to the standard required.

Colorectal cancer (CRC) is a major health problem because it represents around 10% of all cancers and achieves a worldwide estimate of 1.4 million newly diagnosed cases annually, resulting in approximately 700,000 deaths. Approximately 19-31% of patients present liver metastases. At diagnosis, a further 23-38% will develop extra-hepatic disease. Over the past decade, the widespread use of modern chemotherapeutic and biological agents, combined with laparoscopic surgical techniques, has improved the prognosis of metastatic CRC. A better understanding of the biology of the tumor, along with high efficiency of diagnostic and therapeutic methods, as well as the spread of screening programs, will improve the survival of the CRC patients in the near future.

It is fitting that the first book to be published on the new subject of virtual colonoscopy takes the form of an atlas with an abundance of images. Radiolo gists approaching this exciting new technique for detecting colorectal neoplasms will rely on their traditional radiological knowledge gained from experience with several different tools, including computed tomography scanning, double contrast barium enema, computer image processing, and, of course, conventional colonoscopic findings. In many cases, the resulting blend of image information is entirely novel and radiologists will be faced with unfamiliar image artifacts as well as the problem of distinguishing stool from real lesions. This atlas will be of great value to those applying this new technique. In this volume, Abraham H. Dachman, MD, has persuaded most of the world's authorities pioneering virtual colonoscopy to contribute their cases as well as their insights. The material is effectively organized into a preliminary text sec tion of clinical and research issues followed by a well-illustrated, high-quality collection of case images. It is of interest to note that most of the 2D images re main in black-and-white format, whereas the 3D images are often presented in color largely because the 3D software applications are commercial products and therefore more creatively formatted to resemble the pink/orange tint of human colonic mucosa.

More than two million medical students, doctors and other health professionals from around the globe have owned a copy of Davidson’s Principles and Practice of Medicine since it was first published. Today’s readers rely on this beautifully illustrated text to provide up-to-date detail of contemporary medical practice, presented in a style that is concise and yet easy to read. Davidson’s provides the factual knowledge required to practise medicine, explaining it in the context of underlying principles, basic science and research evidence, and shows how to apply this knowledge to the management of patients who present with problems rather than specific diseases. The book has won numerous prizes including being highly commended in the British Medical Association book awards. Davidson’s global perspective is enhanced by the input of an international team of authors and a distinguished International Advisory Board from 17 countries. Building on the foundations laid down by its original editor, Davidson’s remains one of the world’s leading and most respected textbooks of medicine. The underlying principles of medicine are described concisely in the first part of the book, and the detailed practice of medicine within each sub-specialty is described in later system-based chapters. Most chapters begin with a two-page overview of the important elements of the clinical examination, including a manikin to illustrate the key steps in the examination of the relevant system. A practical, problem-based clinical approach is described in the ‘Presenting Problems’ sections, to complement the detailed descriptions of each disease. The text is extensively illustrated, with over 1000 diagrams, clinical photographs, and radiology and pathology images. 1350 text boxes present information in a way suitable for revision, including 150 clinical evidence boxes summarising the results of systematic reviews and randomised controlled trials and 65 ’In Old Age’ boxes highlighting important aspects of medical practice in the older population. A combined index and glossary of medical acronyms contains over 10 000 subject entries. The contents can also be searched comprehensively as part of the online access to the whole book on the StudentConsult platform. Access over 500 self-testing questions with answers linked to the book’s content for further reading. The text uses both SI and non-SI units to make it suitable for readers throughout the globe. A new chapter specifically on Stroke Disease recognises the emergence of Stroke Medicine as a distinct clinical and academic discipline. A rationalisation of the 1350 boxes used throughout the book gives a simpler and clearer presentation of the various categories. New ‘In Adolescence’ boxes recognise the fact that many chronic disorders begin in childhood and become the responsibility of physicians practising adult medicine. These boxes acknowledge the overlap ‘transitional’ phase and highlight the key points of importance when looking after young people. The regular introduction of new authors and editors maintains the freshness of each new edition. On this occasion Dr Ian Penman has joined the editorial team and 18 new authors bring new experience and ideas to the content and presentation of the textbook. An expanded International Advisory Board of 38 members includes new members from several different countries.
