What is a CT scan of the spine?
CT (Computed Tomography, or CAT scan) uses a special X-ray machine to take detailed pictures of the spine. CT scanners create cross-sectional (slices) pictures of the spine. CT pictures are far more detailed than those obtained by standard X-ray. CT is a unique tool because it can show many different types of tissue in the same region (bone, muscle, soft tissue and blood vessels).
