Original Study -2014-
The mare was anesthetized and multiple MRI images were obtained. Significant bone edema was seen distal to the P1 cyst previously noted radiographically. There was a cartilage defect overlaying the cyst and cyst contents were bright on STIR sequences indicating likely articular communication. The fetlock joint was distended and proliferative. Proximal P1 appeared mildly sclerotic.
