Mark is nine-year-old Clydesdale gelding who had a long history of chronic abscessation and white line disease on the left front foot. Dr. Diego De Gasperi stated that “We don’t always scan horses with white line disease, but we started to scan horses with chronic draining tracts from abscesses or more severe white line disease like Mark. We found that scanning these horses has been extremely helpful for us and our farriers to figure out how far back the draining tract goes or how far back we have to debride the hoof walls.” Mark had several hoof wall debridement's and resections and is currently doing well.
