What are Lumbar Spine CT Scans?
A doctor or physician may order a CT scan of the lumbar spine to make detailed pictures and analyze the internal structure. Computerized tomography (CT) scanning is useful to get a very detailed 3D image of certain parts of the body.
The process begins by taking many different X-ray views at various different angles, which are then combined with the use of computer processing to create cross-sectional images of the bones and soft tissue inside of your body, including tissues inside of solid organ. Ordinary X-ray testing does not show clear images of soft tissue, so doctors often request CT scanning to get a good image of soft tissue including organs, muscles, blood vessels, nerves, and the brain. Sometimes a contrast dye is used as it shows up clearer on the screen.
During a quality CT scan of the lumbar spine, a doctor will be able to see cross-sections of your lower back, which is made up of five vertebral bones, large blood vessels, nerves, ligaments, cartilage, and tendons.
