Topic:Scintigraphy
Scintigraphy, also known as nuclear scintigraphy, is a diagnostic imaging technique used in equine medicine to assess bone and soft tissue abnormalities. This procedure involves the administration of a radiopharmaceutical agent that emits gamma rays, which are detected by a gamma camera to create detailed images of the horse's body. Scintigraphy is particularly useful for identifying areas of increased metabolic activity, often indicative of inflammation, infection, or injury. It is commonly employed in cases where lameness or other musculoskeletal issues are present, but the precise location or cause is not easily determined through other diagnostic methods. This page compiles peer-reviewed research studies and scholarly articles that explore the applications, methodology, and diagnostic value of scintigraphy in equine veterinary practice.
Use of nuclear scintigraphy to characterize in intrathoracic mass in a foal. A 2-month-old thoroughbred colt with noisy and difficult respiration was diagnosed as having an intrathoracic mass, using conventional radiographic techniques. Nuclear scintigraphy was then used to characterize the mass, leading to successful surgical removal.
Injury to the origin of the gastrocnemius muscle as a possible cause of lameness in four horses. Four horses were evaluated because of hind limb lameness. Two had a distinct gait abnormality at the walk characterized by lateral rotation of the point of the calcaneus and medial rotation of the toe during the stance phase. Nuclear scintigraphy revealed a focal area of intense radioisotope uptake in the caudodistal aspect of the femur in all 4 horses, and 3 of the horses had a corresponding proliferative reaction on the caudodistal cortex of the femur on radiographs. In all 4 horses, a diagnosis of injury to the origin of the gastrocnemius muscle was made. Three of the horses returned to ath...
