Diagnostic Tool and Treatment Aid MRI: A Highly Effective An EMC series Magnetic Resonance Imaging (MRI), a technology


available for horses, works differently from x-rays and ultrasound by detecting abnormal tissue density and fluid based on tissue response to magnetization. MRI has revolutionized injury detection in horses by under- standing the changes occurring in different tissues with different injuries.


Initially MRI studies could only be completed with horses under general anesthesia in MRI units made for humans. An open magnet was later created for use in standing horses and is in use at The Equine Medical Cen- ter (EMC). The predominate use has been for foot dis- eases, but now with improved software, images of the pastern, fetlock, cannon bone and knee are also possible.


MRI’s greatest advantage to horses is the ability to detect damage to bones, tendons and ligaments. This is particularly true in the horse’s foot be- cause the hoof limits visualization of soft tissues with x-ray and ultrasound. Because MRI creates images in multiple slim slices, a 3-dimensional re- construction can pro- vide the exact location and severity of the injury.

The most common injuries in the foot, only detectable


by MRI, are deep digital flexor tendinopathy, navicular bone inflammation, coffin joint collateral ligament desmopathy, bone bruises and joint distention. EMC has developed MRI guided injection techniques for injuries to the deep digital flexor tendon and collateral ligaments in the foot. This provides an accurate placement of platelet rich plasma (PRP) or stem cells to help treat these injuries.
