Practical Veterinary Diagnostic Imaging is an essential and practical guide to the various diagnostic imaging modalities that are used in veterinary practice. It moves from basic mathematic and physical principles through to discussion of equipment and practical methods. Radiographic techniques for both small and large animals are covered. There is a separate chapter devoted to ultrasound, as well as discussion of advanced imaging techniques such as fluoroscopy, computerised tomography and magnetic resonance imaging. The book also covers legislation and safety issues in the context of their impact on the veterinary practice.
Presented with clear line diagrams and photographs, Practical Veterinary Diagnostic Imaging also provides revision points and self–assessment questions in each chapter to aid study. It is an ideal guide for student and qualified veterinary nurses. It is also a useful reference for veterinary students and veterinarians in general practice who want a basic guide to radiography and other imaging modalities.

Recenzii

This textbook provides a nice overview of the technical aspects of veterinary radiology and will be useful for veterinary technicians and veterinary students.   (Journal of the American Veterinary Medical Association, 15 September 2013)
In summary, this book fills an important niche in the market and will be particularly useful as a quick and concise reference for all in the practice. Additionally, it will provide a useful initial text for those embarking on diagnostic radiography.   (The Veterinary Journal, 1 August2013)
In summary, Practical veterinary diagnostic imaging is a radiography textbook that is suitable for veterinary
and veterinary nurse students who would like to increase their knowledge.   (Australian Veterinary Journal, 1
March 2013)

Readers looking for a concise overview or review of diagnostic imaging physics and positioning will find that this book fits the bill.   (Doody s, 4 January 2013)
"Students and veterinary nurses alike receive a handy reference to everything needed to know about diagnostic imaging in veterinary practice, including the basic principles of physics: all accompanied by illustrations key to understanding."  (Midwest Book Reviews, 1 December 2012)
My first impressions of this colourfully bound paperback are that it is inviting, and not as intimidating as some veterinary books. It clearly delivers what it promises, but lacks something in the monochrome presentation of all the text, photographs, figures and diagrams. It is, though, a welcome resource for any veterinary practice.   (Veterinary Record, 20 October 2012)
