Description
Book SynopsisAcomplete, all-in-one resource for head and neck imaging in dogs, cats, and horses Veterinary Head and Neck Imaging is a comprehensive reference for the diagnostic imaging of the head and neck in dogs, cats, and horses. The book provides a multimodality, comparative approach to neuromusculoskeletal, splanchnic, and sense organ imaging. It thoroughly covers the underlying morphology of the head and neck and offers an integrated approach to understanding image interpretation. Each chapter covers a different area and discusses developmental anatomy, gross anatomy, and imaging anatomy, as well as the physical limitations of different modalities and functional imaging. Commonly encountered diseases are covered at length. Veterinary Head and Neck Imaging includes all relevant information from each modality and discusses multi-modality approaches. The book also includes: A thorough introduction to the principles of veterinary head and neck imaging, including imaging technology, interpr
