CT Lumbar Spine - Overview & Technique

A computed tomography (CT) scan of the lumbar spine is an imaging method that uses x-rays to create cross-sectional pictures of the lower back (lumbar spine). This cross-sectional imaging technology allows the radiologist to look at different levels or slices of the lower back using a rotating X-ray beam. The radiologist is able to view each slice to assess for injuries, including ruptured disks and other bony abnormalities. In the imaging center, you will be asked to lie on a narrow table that slides into the center of the CT scanner. You will lie on your back with your arms up over your head. Once you are inside the scanner, the machine's x-ray beam rotates around you. (Modern "spiral" scanners can perform the exam in one continuous motion.) Small detectors inside the scanner measure the amount of x-rays that make it through the lower back. A computer takes this information and uses it to create several individual images, called slices. These images can be stored, viewed on a monitor, or printed on film. Three-dimensional models of the lumbar spine can be created by stacking the individual slices together.

CT Lumbar Spine - Alternative Names and Explanations

CAT scan - lumbar spine, L-spine CT, Computed axial tomography scan - lumbar spine, Computed tomography scan - lumbar spine, CT Scan -  Lumbar Spine w/o contrast 72131, CT Scan -  Lumbar Spine with contrast 72132, CT Scan -  Lumbar Spine with & w/o contrast 72133

CT Lumbar Spine - Benefits (versus Other Diagnostic Options)

• Spinal CT scanning is a rapid procedure and offers an accurate evaluation of bone and most soft tissues. Using the latest equipment, the spine may be displayed in multiple planes and three-dimensional imaging is an option.
• A major advantage of CT is its ability to image bone, soft tissue and blood vessels all at the same time.
• CT is better than MRI at detecting fractures of the lumbar spine.

CT of the Lumbar Spine - Indications, Common Uses, & Positive Findings

• Spinal Trauma
• Vertebral Fracture
• Vertebral dislocation
• Spondylolisthesis
• Causes of lower back pain, with or without prior surgery
• Pain/radiculopathy in adults not improving despite 4 weeks of non-surgical treatment, which includes physical therapeutic modalities and appropriate pharmacologic intervention.  The 4-week requirement for treatment need not be applied to the pediatric patient or to those with documented rheumatologic disease with joint involvement.
• Acutely in the setting of major trauma.
• Recent less severe trauma to the spine with abnormalities on neurologic exam or x-ray or persistent increasing localized lower back pain.
• Clinical suspicion of an infectious process such as abscess, osteomyelitis, or discitis involving the spine, spinal cord, or adjacent structures or spaces.
• Known diagnosis of cancer with suspicion of metastases to the lumbar spine, meninges, or spinal cord.
• Further investigation of spinal abnormality of unknown or uncertain cause seen on plain film.
