Occasionally a PET study in a standing horse may be degraded by the animal moving inside the scanner. MILE-PET® employs sophisticated algorithms to correct for such motion. Motion correction is particularly helpful in proximal joints such as carpi and hocks, but is also helpful in other joints when the horse is restless under sedation.
