This handbook provides an overview of diagnostic imaging— predominantly radiology and ultrasonography—as it pertains to general small animal practice. Important principles and key abnormalities are outlined for each body part. Part I addresses the process of image interpretation. Part II describes the imaging of the musculoskeletal system. Part III explores the unique demands of imaging the thorax and the abdomen and includes a chapter on abdominal ultrasound. Part IV displays the imaging challenges of specific canine and feline cases along with their diagnostic outcomes. The final section, Part V, contains a concise Index of Figures for easy reference to visual support; an imaging-specific Glossary of Terms; a list of Suggested Reading resources for more in-depth study; and a helpful Subject Index for quick access to particular conditions, techniques, and cases.
