Magnetic Resonance Imaging (MRI)

MRI (Magnetic Resonance Imaging) is an imaging technique that involves placing the horse within a strong magnetic field. Radio waves are applied to the area to be examined and the signal produced is analysed by a computer to produce an image. The high tissue contrast achieved allows assessment of cartilage, ligament, tendons, joint capsule and bone; all on one image. MRI can image deep inside structures and in three dimensions so changes can be found that may not be seen using other imaging e.g. x-ray. MRI is most commonly used for lameness investigations.
