"The strengths of this comprehensive text include its easy use, quick access to current and complete information, understandable diagrams and tables, and good quality images. This is a one-of-a-kind textbook that will be an excellent reference for veterinarians and veterinary medical students seeking comprehensive information about particular diagnostic procedures or laboratory tests." (Veterinary Clinical Pathology, 2011) "This impressive textbook is well worth the cost and will make a valuable addition to any veterinarian's reference library." (Journal of the American Veterinary Medical Association, March 2010)"This impressive textbook is well worth the cost and will make a valuable addition to any veterinarian's reference library." (Vet Med Today, 15 March 2010)"There are clinical pathology books, diagnostic imaging books, and diagnostic procedure books, but this is the first of its kind. A brief review of topics includes general principles for performing fecal tests, angiography, brain ultrasonography, and cardiac catheterization. The cardiac catheterization chapter includes waveforms and critical values and is a fantastic example of the balance achieved by the authors. The topics are both concise and thorough. Each topic is presented in a standardized format that is easy to scan, making this a valuable book for practitioners, veterinary students, and residents in training." (Doody's Reviews, March 2010)"I recommend this book strongly to every practice." (Veterinary Practice, November 2009)
