In the standing, sedated horse, we are able to examine the head, upper neck and distal limbs. Scanning the head and upper part of the neck aids in the diagnosis and treatment of dental and sinus problems, as well as evaluating patients who are showing signs of headshaking or have sustained a head trauma. With the enhanced capability of the new machine, scanning of the distal limbs without the need for a general anaesthetic is hugely beneficial in the diagnosis of lameness caused by bone or soft tissue injuries or disease.
Under general anaesthesia, we can scan further regions including the entire neck, the equine thoracic spinal column, back, pelvis, sacroiliac and stifle joints, and proximal limbs.
CT scans are particularly useful for cases showing neck pain, unexplained lameness and neurological problems, and in which radiographs and ultrasound scans were inconclusive or normal.
How does it work?
The CT scanner rotates around the area of the patient being imaged to take hundreds of extremely detailed x-ray images (‘slices’) from different angles. These are then converted to 3D images using sophisticated technology.
Scans can be completed in minutes and provide exquisitely detailed images.
A multi-disciplinary approach
Our clinicians will review the horse’s history and results of other tests prior to the scan. In many cases clinicians from several departments will be involved (such as dentistry, neurology and surgery). This multi-disciplinary approach affords the best chance of a successful outcome.
When do we use CT?
Examples of types of injury or conditions suitable for evaluation using CT are:
- Teeth disorders
- Sinus problems
- Traumatic injuries to the head and upper neck
- Some types of brain disorder
- Headshaking
- Ear, nose and throat conditions
- Orthopaedic conditions of the limbs
- Complex fracture evaluation and surgical planning
Should your horse require a CT scan, a general anaesthetic may be necessary, depending on the area of interest and the temperament of the horse or pony, but many animals can be scanned while standing and sedated.
When a diagnosis has been made, our specialist clinicians will discuss with the client and the referring veterinary surgeon the best way to treat and manage the horse or pony to maximise the chance of treating the condition successfully. We can advise referring veterinary practices regarding treatment at home, however many owners and referring vets prefer specialised treatments to be carried out here at Rossdales.
