Magnetic resonance imaging study in horses.

This research project aims to study the use of both high- and low-field MRI in examining lameness in the lower limb of horses, with a particular emphasis on the fetlock region. The researchers are seeking to collect equine cadaver samples, specifically from horses that have experienced fetlock pain.

Collection of Samples

• The researchers are seeking the help of their colleagues in the collection of equine cadaver fetlock samples. They want samples from horses with a known history of fetlock pain.
• The aim of this research study is to gather limbs from horses experiencing forelimb lameness unimproved by palmar digital nerve block but improved with either an abaxial sesamoid block, a low four-point block, or an intra-articular fetlock joint block.
• Initially, pairs of forelimbs ideally removed at the mid-carpal joint level and frozen within 6-12 hours post-euthanasia. Of course, the collection of any limbs must be done with the horse owner’s permission.

Study Objectives

• The purpose of this study is to investigate and understand better the benefits and limitations of high- and low-field MRI in dealing with equine lameness in the distal limb. The research specifically targets the fetlock region, where there is data scarcity on significant MRI findings.
• The researchers also plan to enhance their knowledge of the type of abnormalities with clinical significance. They are keen to provide feedback to participating colleagues on the MRI findings and postmortem examinations of the equine samples.

Relevance of Study

• This study is crucial due to the increasing use of MRI in equine veterinary practice. It will help enhance understanding and knowledge around resolving equine lameness issues in the distal limb, particularly concerning the fetlock region which suffers from limited pre-existing data.
