Nuclear Scintigraphy / Bone Scan 


  • Dedicated scintigraphy suite
  • Large, climate controlled air conditioned room
  • Gamma camera with overhead gantry suspension
  • Micas computer system
  • Designated radiation safety stables contained within unit



Nuclear scintigraphy or bone scanning is an advanced diagnostic imaging modality.

It is especially useful in the investigation of lameness originating from multiple areas simultaneously, in needle-shy patients, or in the identification of regions of injury that are inaccessible to nerve blocks or basic imaging e.g. the pelvis. Some lamenesses are so severe that nerve blocks are contra-indicated due to the risk of worsening an injury. Some pathologies can solely be identified by scintigraphic imaging.

Horses are admitted to the hospital the day before the bone scan. A radioisotope, technetium 99m is injected intravenously and the scans are obtained using a gamma camera over the next few hours. These are analysed using our Micas computer system. The horse remains mildly radioactive after this procedure and therefore has to remain in isolation until radiation levels fall to a safe level, usually after 48 hours.

Further lameness investigation may then be performed at Endell Equine Hospital or by your own referring veterinary surgeon. Diagnostic imaging with radiography or ultrasonography may be indicated, focusing on the areas identified by IRU (increased radiopharmaceutical uptake / hot spots). Focussed treatment and a rehabilitation program can then be implemented.
