A computed tomography (CT) scan uses X-rays to make detailed pictures of the spine and vertebrae in the neck (cervical spine), upper back (thoracic spine), or lower back (lumbosacral spine).

The radiologist may discuss the CT scan with you right after the test. However, complete results usually are ready for your doctor in 1 to 2 days.

Normal:	Spinal bones (vertebrae) are normal in shape, number, and alignment.
	The discs and joints that support the spine are normal.
	The spinal canal is normal in size and shape.
	If contrast material is used, it flows evenly through the spinal canal. No narrowing or blockage of the spinal canal is present.
	None of the nerves leaving the spinal cord are compressed or pinched. No growths or bulges are present.
Abnormal:	Spinal bones (vertebrae) are missing, damaged, or out of alignment.
	One or more discs may be damaged. One or more herniated discs are found.
	The flow of contrast material through the spinal canal is restricted or blocked indicating narrowing of the canal (spinal stenosis).
