Bone Scans in Horses Not Always Accurate in Poor Performance Exams
In theory, nuclear scintigraphy (bone scanning) sounds like the ideal imaging modality to localize problem areas in horses’ bodies. Veterinarians inject a radioisotope into the horse, which gets deposited in areas where bone is changing rapidly, as often occurs at healing injury sites. Then, they use special gamma cameras to acquire images that show these rapidly changing areas. Easy, right?
Not so fast. Recent research suggests that bone scans in horses aren’t always accurate in diagnosing causes of lameness and poor performance in sport horses when used alone.
However, said Sue Dyson, MA, VetMB, PhD, DEO, FRCVS, head of Clinical Orthopaedics Animal Health Trust Centre for Equine Studies, in Newmarket, U.K., bone scans in horses used alongside other imaging modalities and diagnostic procedures can provide clinically useful
