A year ago, Santa Anita Park installed the world's first MILE-PET device, a positron emission tomography (PET) scanner specifically designed to image standing horses (without the need for general anesthesia). Over the past 12 months, more than 188 PET studies were performed on over 100 horses, with some studies imaging horses more than once to follow bone changes over time. With support from CEH and the Stronach Group, a MILE-PET scanner will be installed at the UC Davis veterinary hospital in 2021.
