Radiology for Horses: Overview & Uses

Radiology, or X-ray imaging, is a vital diagnostic tool in equine veterinary medicine. It allows veterinarians to examine a horse’s bones and some soft tissues to diagnose injuries, diseases, and abnormalities.

Uses of Equine Radiology

• Lameness Evaluation – Detects fractures, arthritis, bone chips, and joint degeneration.

• Hoof Conditions – Diagnoses laminitis, navicular disease, and abscesses.

• Dental Issues – Assesses tooth alignment, infections, and sinus problems.

• Orthopedic Concerns – Identifies bone cysts, spurs, and developmental disorders in young horses.

• Pre-Purchase Exams – Ensures a horse has no underlying skeletal issues before buying.

How It Works

A portable X-ray machine emits radiation that passes through the horse’s body, capturing images on a digital plate. Dense structures like bones absorb more radiation and appear white, while softer tissues appear darker.

Types of Radiology Used in Horses

• Digital Radiography (DR) – Produces immediate high-quality images for quick diagnosis.

• Computed Radiography (CR) – Uses a special plate to process images digitally.

• Contrast Radiography – Involves injecting contrast agents to highlight soft tissues and joints.

Safety & Considerations

• Requires proper restraint, often done with sedation.

• Veterinarians and handlers wear protective lead gear to limit radiation exposure.

• Best used in combination with ultrasound or MRI for soft tissue evaluation.

Radiology is a non-invasive and widely used tool for diagnosing and monitoring equine health conditions.
