Computed Tomography (CT scan)
What is Computed Tomography (CT)?
A CT image is a computerised imaging procedure produced by a narrow beam of x-rays which are quickly rotated around the point of interest. This produces signals that are then processed by the computer to generate cross-sectional images or ‘slices’ of the body. These slices contain considerably more detail than conventional x-rays and can be stacked together to produce three dimensional images. Additionally these images can then be reconstructed allowing the same piece of anatomy to be viewed in different orientations. Such a technique allows us to see very subtle changes in bone and soft tissue related to injury and disease.
When is CT imaging useful?
Computed Tomography is the best diagnostic tool available for assessing bone injuries as well as giving high resolution images of soft tissues. We use CT imaging for a number of conditions mostly relating to the head and neck understanding sedation. CT images can also be produced for the distal limb (lower leg). To image the limb it is essential no movement occurs so this procedure happens under general anaesthetic.
CT imaging is used when we suspect conditions of:
· Sinus cavities
· Nasal passages
· The Skull – masses or fractures
· Cervical vertebrae
· Brain and neck lesions
· Headshaking
· Dental conditions
· Bony changes in the legs
In addition CT images can be useful prior to surgery in some cases.
Where will the scan take place?
We utilise the CT service at Rossdales Equine Hospital to provide this diagnostic tool to our patients.
