Characteristic findings of magnetic resonance imaging (MRI) and computed tomography (CT) for severe chronic laminitis in a Thoroughbred horse.
Abstract: A Thoroughbred horse with severe chronic laminitis of both forelimbs was evaluated on the same day with magnetic resonance imaging (MRI) and computed tomography (CT). Both MRI and CT revealed loss of the dorsal aspect of the cortical bone of the 3rd phalanx and sclerosis. CT reflected the status of the horny layer and bone of the affected feet, while MRI depicted inflammation of the laminar corium, together with tendon edema. On the 3-dimensional CT venogram, vessels were visualized in both the right and left forelimbs, although there was a difference in the vasculature of the coronary plexus and circumflex vessels between the right and left forelimbs. A combination of both MRI and CT provides detailed information regarding pathological conditions.

The research focuses on the use of MRI and CT scans to diagnose and study severe chronic laminitis in a Thoroughbred horse, detailing the different observations gleaned from each method and highlighting how a combination of both can provide a comprehensive view of the condition.
Methodology and Findings
- The team used both magnetic resonance imaging (MRI) and computed tomography (CT) to assess a Thoroughbred horse afflicted with severe chronic laminitis in both of its forelimbs.
- Both MRI and CT scans revealed specific damage to the horse’s anatomy including the loss of the dorsal aspect of the cortical bone of the 3rd phalanx and sclerosis, a hardening of the body tissue.
Comparative Analysis of MRI and CT
- The researchers found that each imaging method gave insights into different aspects of the disease. The CT scan showed the status of the horny layer and bone of the affected feet.
- The MRI, on the other hand, revealed inflammation of the laminar corium, a specific part of the hoof, along with tendon edema, an accumulation of excess watery fluid in cavities or body tissues.
3-Dimensional CT venogram
- The researchers also performed a 3-Dimensional CT venogram, a type of imaging test that helps visualize blood flow through veins in the horse’s forelimbs.
- In this study, it notably revealed differences in the vasculature between the right and left forelimbs, specifically differences in the coronary plexus and circumflex vessels.
Conclusion
- From this investigation, it’s clear that a combination of both MRI and CT can offer a holistic and detailed insight into the pathological conditions related to chronic laminitis, demonstrating how they might together provide a fuller picture of the disease’s impacts for more effective diagnosis and treatment.
