When to consider advanced imaging (MRI and CT)
Cross-sectional imaging modalities – magnetic resonance imaging (MRI) and computed tomography (CT) have significantly advanced diagnostic imaging in equine patients, particularly in the distal limb, head and neck.
MRI has revolutionised the diagnosis of lameness localised to the distal limb, allowing a definitive diagnosis, and therefore more accurate prognosis, to be given in many horses with no abnormalities, or equivocal findings, on conventional imaging techniques. Similarly, CT has dramatically improved our ability to diagnose conditions of the equine head, particularly dental pathology and conditions affecting the paranasal sinuses, which can be very challenging to diagnose on radiographs.
