""This title remains the definitive textbook of veterinary radiology...covers normal and abnormal imaging anatomy of dogs, cats, and horses,... primarily focuses on radiograph interpretation, although it includes ultrasound, CT, and MRI findings as appropriate. The purpose is to teach radiographic interpretation centered around description using roentgen signs.... achieves this goal with direct and succinct text combined with illustrative and highly annotated examples of imaging findings throughout…. organized as both a textbook for students and as a reference guide for general and specialty practitioners. The book’s biggest strength is its images, as it should be for a radiology book. These are generally well annotated, allowing for easy identification of important structures and lesions.... Veterinary radiology is an ever-expanding field which justifies serial updates to the book, represented by this new edition."" ©Doody's Review Service, 2025, Jennifer M Reinhart, DVM, PhD, DACVIM (SAIM), DACVC (University of Illinois College of Veterinary Medicine)
