Radiography is one of the most commonly used diagnostic tools in veterinary practice. It provides a large amount of information to the veterinarian by noninvasive and economical means. It does not alter the disease process or cause unacceptable discomfort to the animal. Although radiography itself is painless, sedation is often desirable in order to reduce anxiety and stress associated with the procedure, as well as to control pain associated with manipulation of animals with painful disorders such as fractures and arthritis.
