Clinical Radiology of the Horse is the best–selling, practical guide to all areas of equine radiography and radiology written by an experienced group of clinicians with a broad range of backgrounds. As with previous editions, this fourth edition provides more than 700 normal and clinical images including annotated radiographs and line diagrams. Many of the images have been replaced by digital images, and there are also many new illustrations, both in the textbook and on the companion website. It provides a comprehensive guide both to the techniques used to obtain radiographs of the horse, and to radiographic interpretation. The normal radiographic anatomy of immature and mature horses is presented with normal variations, incidental findings, and details of significant abnormalities. Remarks on clinical prognosis and treatment are also included. The text has been updated to include new information, knowledge gained from continued clinical experience and the most relevant references from recent literature. The emphasis throughout is on practical tips, common pitfalls, and the techniques used to obtain the best radiographs of specific areas and conditions.
The fourth edition has been completely updated and now fully reflects the move to digital imaging. Additional changes to this edition include major revisions to the chapters on the head, thorax, and abdomen; expansion of and division into three chapters for the foot, pastern, and fetlock; and further reading lists organised under sub–headings for ease of reference. The focus still remains on radiography and radiology, but the authors reference situations in which other imaging techniques may be appropriate and provide suggestions for further reading.
This edition also includes access to a password–protected website with all the images from the book as well as 150 additional images with examples of more subtle lesions, more fractures, correct technique and positioning versus incorrect, immature horses, progression of disease, and pathological images.
Clinical Radiology of the Horse, Fourth Edition will be invaluable all who take or read equine radiographs, including students, veterinary practitioners who x–ray horses relatively infrequently, and to equine specialists.
