Use of magnetic resonance imaging in equine lameness diagnosis

Magnetic resonance imaging (MRI) has been used for skeletal and central nervous system imaging in humans for years. It is currently the imaging modality of choice for examination of soft tissue intraarticular injuries such as ligament and meniscal damage. Equine studies have been performed in cadaver specimens of the carpus, metacarpophalangeal joint, femorotibial/femoropatellar joints, flexor tendons, and foot. Current technology provides diagnostic images but does not allow in vivo imaging of horses. Newer technology may allow imaging of distal limbs in standing, sedated horses.
