Lumbar spine computed tomography scan

Computed tomography (CT) of the lumbar spine is an advanced diagnostic imaging method used to provide detailed visualization of the lumbar vertebrae, intervertebral discs, spinal canal, and surrounding tissues. This examination produces comprehensive images of bony, cartilaginous, ligamentous, and neural structures, helping identify various conditions that may cause lower back pain.

What is a Lumbar Spine CT Scan?

Computed tomography (CT) is an imaging examination that uses X-rays and computer processing to create detailed cross-sectional images of the body's internal structures. A lumbar spine CT scan is particularly useful for evaluating bony structures such as vertebrae and for detecting degenerative changes, fractures, spinal stenosis, and intervertebral disc herniations.

When is a Lumbar Spine CT Scan Performed?

This examination is most commonly performed when the following conditions affecting the lumbar spine are suspected or diagnosed:

• Back pain: chronic or acute lower back pain with an unclear cause.
• Intervertebral disc disorders: disc herniation, disc protrusion, or degenerative disc disease.
• Spinal stenosis: narrowing of the spinal canal that compresses the spinal cord or nerve roots.
• Spinal trauma: vertebral fractures or cracks.
• Tumors: primary or metastatic tumors of the spine.
• Inflammatory diseases: spondylitis, arthritis.
• Radiculopathy: compression or injury of nerve roots causing pain, numbness, or weakness in the legs.
• Pre- and postoperative assessment: planning surgical intervention or evaluating postoperative outcomes.

Procedure at the Clinic

A lumbar spine CT scan is performed in the radiology department.

1. Preparation: the patient lies on the CT examination table. Removal of metal objects (such as jewelry) may be required.
2. Examination: the CT scanner acquires a series of X-ray images while the patient lies on the table. It is important to remain still throughout the procedure.
3. Contrast agent (if required): in some cases, an intravenous contrast agent may be administered to obtain more detailed images.
4. After the procedure: the patient may be observed for a short period.

The procedure is quick and generally well tolerated.

Interpretation of Results

The CT images are analyzed by a radiologist, who evaluates the condition of the vertebrae, intervertebral discs, spinal canal, and surrounding tissues, looking for abnormalities such as disc herniations, spinal stenosis, fractures, tumors, or inflammatory changes. The examination results are provided as a written report together with the image set. These findings serve as important information for the treating physician (for example, a neurologist, neurosurgeon, or orthopedic specialist), helping establish an accurate diagnosis and develop an appropriate treatment plan.
