Commonly referred to as CT scans, Computed Tomography is a technology that uses very small x-ray beams from many different angles around the body (called a slice) that are reconstructed by computer to produce an image. The tissue images show up on the monitor as black, white and shades of gray (called the gray scale). The amount of gray shows the ability of different tissues to absorb the x-ray beam, helping to identify normal and abnormal tissue. Our hospital uses a Tomoscan M for this procedure. San Luis Rey Equine Hospital is one of the few veterinary hospitals in the world to offer this diagnostic procedure, performing approximately 100 scans yearly.
