The spinal cord is made up of three bones: lumbar, dorsal, and cervical. The dorsal spine, the middle portion of the cord, comprises 12 vertebrae and forms the largest portion. A CT scan with a Virtualscopy test of the dorsal spine gives a 3D scanned image of the spine. It is useful in getting a clear picture of the condition of the bones and helps in detecting any abnormalities in the same. Back pain and multiple sclerosis are the most common symptoms that call for a CT scan test of the dorsal spine. It is a relatively painless procedure.
