  • At Ashbrook Equine Hospital, we are very excited to be able to offer MRI investigation of lameness problems.

    Magnetic Resonance Imaging (MRI) provides an image of tissue when a magnetic field is applied and the molecules in the tissue then ‘resonate’ or wobble. The resulting signal is different from each type of tissue so we can build up a picture of the structures and any unexpected signal within a tissue highlights a problem area. The images are taken in ‘slices’ with each MRI consisting of about 500-600 images which are then individually interpreted by a specialist consultant.

  • These multiple images allow us to be incredibly precise about localising the cause of a lameness problem. A definitive diagnosis such as this means we can then provide a much more accurate prognosis and a highly specific treatment plan to help your horse return to the work he should be doing.

     

    MRI has been most beneficial for cases of persistent lameness that we know are isolated to the foot region. The hard hoof capsule limits our ability to image structures within the hoof; radiographs only provide details about the bone structure and ultrasound scanning is limited by the hoof capsule so we cannot visualise the multitude of tendons and ligaments. MRI is able to ‘see’ into the hoof capsule and provide detailed information about this very complex structure. We are now also able to use MRI to image the pastern, fetlock, cannon bone region and even the knee and some of the hock. These images can add a huge amount of additional information to the radiographs and ultrasound scans that are undertaken as part of a routine lameness investigation. We can even use repeat MRI scans to show the progression of an injury.

  • After traditional lameness investigation which may include nerve blocks, joint blocks, radiographs and ultrasound examination, the vet may feel they have not reached a definitive diagnosis so may recommend MRI.

    When a horse is admitted for MRI, we allow them a night of hospitalisation to settle into our hospital environment. A more settled horse means we will obtain higher quality images with less sedation. On the day of the MRI, the horse has an intravenous catheter placed to allow sedation to be given easily. The horse’s shoes are removed and radiographs taken to ensure no metal fragments remain in the hoof as metal will render the images as non-diagnostic.

  • After this preparation, the horse enters the MRI suite. The scans are taken with the horse standing and the affected limb positioned in a large U shaped magnet. The images are obtained over a 1-3 hour period, depending on which area is to be scanned. The images are sent electronically to an image interpreting specialist. We usually expect the report from the consultant to be ready within 72 hours, at which time your vet will then be able to discuss the results and formulate the most appropriate treatment plan with you.
