Computed tomography (CT) is an scanning process that uses specially developed x-ray technology to make images of the inside of the body. It is also called computerised tomography and computerised axial tomography (CAT).
The results of a CAT scan is a series of pictures that can be viewed individually (2-dimensional), or as a whole (3-dimensional).
CT is a powerful way of diagnosing problems in bony structures such as the the foot and ankle, and is commonly in conditions such as:
- Bone Tumours
- Fractures – acute and stress fractures
- Flat feet
- Degenerative and rheumatoid arthritis
- Avascular necrosis
CT offers some significant advantages over other X-ray techniques, because it can show the exact location and configuration of soft tissues and bones in the foot and ankle. CT scanning is also more accurate than conventional X-rays in determining the extent of some bone tumours, and provides critical information about how the disease has progressed, and therefore how to treat it.
