Detailed Spinal Imaging with Spinal CT Scan
Spinal CT, also known as spinal computed tomography, is a diagnostic imaging test that uses x-rays to create detailed cross-sectional images of the spine.
This non-invasive procedure allows physicians to visualize the bones, discs, nerves, and soft tissues of the spine in great detail.
Spinal CT is often used to diagnose a variety of spinal conditions, including vertebral fractures, herniated discs, spinal stenosis, and spinal cord injuries. It can also help in the evaluation of bone spurs, degenerative disc disease, and other spinal abnormalities.
During a spinal CT scan, the patient lies on a table that slides into a donut-shaped machine called a CT scanner. The scanner rotates around the body, capturing multiple x-ray images from different angles.
These images are then processed by a computer to create detailed cross-sectional images of the spine.
What is the Purpose of Performing a Spinal CT Test?
Spinal CT scans are performed to help diagnose and evaluate a wide range of spinal conditions. They are particularly useful in cases where a more detailed visualization of the spine is needed than what can be provided by conventional x-rays.
Some common scenarios where a spinal CT scan may be recommended include:
- Suspected vertebral fractures after a traumatic injury
- Evaluation of herniated discs causing back pain or sciatica
- Assessment of spinal stenosis, a narrowing of the spinal canal
- Diagnosis of fractures or dislocations in the spine
- Evaluation of spinal cord injuries from trauma
By providing detailed images of the spine, a spinal CT scan can help physicians accurately diagnose spinal conditions, plan appropriate treatment, and monitor the effectiveness of interventions.
What are the Costs of Spinal CT Tests in India?
The cost of a spinal CT scan in India can vary depending on several factors, including the location of the imaging center, the complexity of the scan, and whether contrast dye is used.
On average, the price range for a spinal CT scan in India can be anywhere from INR 5,000 to INR 15,000.
Factors that can influence the cost of a spinal CT scan include the specific region of the spine being imaged, the need for additional views or images, and the use of contrast dye to enhance the visibility of certain structures.
It is important to check with the imaging center or hospital for an accurate estimate of the cost before undergoing the procedure.

Frequently Asked Questions
How does a spinal CT scan differ from an MRI?
A spinal CT scan uses X-rays to create detailed images of the bones in the spine, while an MRI uses magnetic fields and radio waves to produce detailed images of the soft tissues like discs, nerves, and spinal cord in the spine.
What Do High Spinal CT Levels Indicate?
High spinal CT levels can indicate a variety of underlying issues, depending on the specific parameter being measured.
What Do Low Spinal CT Levels Indicate?
Low spinal CT levels can also point to various underlying issues within the spine.
What conditions are best evaluated using a spinal CT scan?
Spinal CT scans are helpful for evaluating conditions like spinal fractures, degenerative disc disease, spinal stenosis, and spinal cord injuries.
How is a spinal CT performed?
During a spinal CT scan, you'll lie on a table that slides into a machine. The scanner takes a series of X-ray images of your spine from different angles to create detailed cross-sectional pictures.
How long does a spinal CT scan take?
A spinal CT scan usually takes about 10 to 30 minutes to complete.
What preparations are required for a spinal CT scan?
For a spinal CT scan, you will need to remove any metal objects and change into a hospital gown. You may be asked to fast before the scan.
Can a spinal CT detect disc herniation or spinal fractures?
Yes, a spinal CT can detect disc herniation and spinal fractures by providing detailed images of the spine's bones and soft tissues.
How accurate is a spinal CT in diagnosing spinal stenosis?
A spinal CT scan can accurately diagnose spinal stenosis by providing detailed images of the spine to help identify any narrowing of the spinal canal or neural foramina.
Is spinal CT used to evaluate soft tissue injuries?
No, spinal CT is not typically used to evaluate soft tissue injuries. It is more useful for evaluating bone structures and detecting conditions like fractures or degenerative changes in the spine.
