MRI technology evolves as a diagnostic tool; CTA research underway at UC-Davis to study foot injury, lameness


CT is much more versatile for the head and sinuses, as well as limbs. Helical scanners have been available for a long time in human medicine. The current push in the medical field is to move from single detectors to multiple detectors, so that a lot of helical scanners are becoming available on a secondary or "used equipment market", which is very beneficial for veterinary medicine.

"In my opinion, it is only a matter of time until veterinary clinics will take advantage of this technology," she says. "As a researcher, I would like to do a comparison of MRI and CT in the same animal, and I think someone needs to develop a technique for giving MRI contrast material."

Continuing education is important. Both CT and MR require a significant amount of continuing education. Particularly if many private practices are obtaining MR and CT, then both are very difficult in interpretation. A steep learning curve is necessary to become trained in interpretation as well as use. Veterinarians need to stay on top of continuing education to say that they are doing a good job. At this time, there is a dearth of available resources for the practitioner to become educated. Universities and those skilled with both modalities must provide advanced education to equine practitioners.

The area of the foot, lameness and the navicular bone of the horse is a sight of a very common and serious clinical problem. "The earlier we can detect these injuries, the better off we are going to be as far as treating them," Tucker explains. "We are very excited about the opportunity that we have for a much-earlier and more-reliable diagnostic imaging modality to intervene when there is still an opportunity for success."
