Results

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.
