Diagnostic imaging is an exciting, rapidly evolving sector of equine medicine. Using non-invasive techniques, we are able to visualize nearly every structure in the equine body. Fifty years ago, obtaining this type of highly detailed information was not possible. We are now able to make specific diagnoses of problems, find these problems earlier, and treat horses with more targeted therapies. Ultimately, this allows us to keep horses leading healthy, pain-free lives for longer.
