The technology of diagnostic imaging can help the veterinarian to assess the athlete’s soundness. For horses, techniques include ultrasound (sonography), radiography, and thermography.

Thermography measures body surface temperature and depicts inflammation by detecting and displaying heat.

Because animals can’t verbally communicate the location and extent of pain, detecting a source of discomfort challenges the equine practitioner. Thermography can help identify the source of pain.
