3T MRI Imaging of the Equine Hock – Bone Edema

Patient History

A 5 year old Quarter Horse Gelding presented to Animal Imaging for an MRI of the left hock in early October 2014. An acute grade 4/5 left hind lameness was noted after a work, a week prior to our diagnostic studies. The lameness was localized to the hock by the referring DVM with intra-articular anesthesia of the tarsal-metatarsal joint and distal intertarsal joint. Lower limb blocks were unsuccessful in alleviating the lameness. No palpable swelling or pain was noted upon evaluation of the left hind limb. A region of interest scintigraphic exam was performed to rule out any stress fracture.
