In 2005 St David’s Equine Practice Installed A New Scintigraphy Unit, Complete
With The Most Recent Data Collection And Analysis Software.
We offer scintigraphy as a service to our colleagues in the South West as an aid
to the diagnosis of orthopaedic cases.
We are happy to carry out scintigraphy as a stand alone service, with the horse
returning home for further work-up. Alternatively we can offer full orthopaedic
work-up and surgery if required.
Scintigraphy Applications
Scintigraphy is established as a key tool in the investigation of the causes of
equine lameness and other skeletal conditions including:
- Stress fractures.
- Disorders of the spine, pelvis and sacro-iliac joint.
- Lameness originating from multiple sites.
- Obscure or intermittent lameness.
- Poor performance of orthopaedic origin.
- Tooth root abscesses.
- Sinusitis.
Scintigraphy Principles
The short-acting radio-pharmaceutical 99m Technetium is temporarily incorporated
into bone and is detected with a gamma camera. The radiopharmaceutical is preferentially
incorporated into areas where bone turnover is high and these will be highlighted
as “hot spots” on the resulting scan picture. Areas of increased bone turnover occur
in diseases such as arthritis, fracture and osteomyelitis.
