Donald E. Thrall, Ian D. Robertson Atlas of Normal Radiographic Anatomy and Anatomic Variants in the Dog and Cat, 3rd Edition, provides an in-depth look at both normal and non-standard subjects, along with demonstrations of proper technique and image interpretations. Expert authors Donald E. Thrall and Ian D. Robertson describe a wider range of "normal" as compared to other books — not only showing standard dogs and cats, but also non-standard subjects such as overweight and underweight pets and animals with breed-specific variations. Each body part is put into context with a description that helps explain why a structure appears as it does in radiographs, enabling you to appreciate variations of normal based on an understanding of basic radiographic principles.
