Spine CT

A spine CT provides detailed views of the vertebrae and surrounding structures. It is very useful for complex fractures and bone abnormalities that are hard to evaluate on X-ray.

Main uses

A spine CT is often used to assess fractures after an accident, especially when a complex bone injury is suspected. It also helps plan spinal surgery.

In degenerative conditions, CT can show narrowing of the spinal canal (stenosis) and bony spurs pressing on nerves.

Image reconstruction

A key advantage of CT is the ability to create three-dimensional and multiplanar reconstructions, so doctors can view bone from many angles. This is very helpful for surgical planning.

However, CT is not as good as MRI for assessing nerves, the spinal cord, and discs. For this reason, both exams are often performed together.

Preparation and limitations

Preparation is usually minimal, and contrast is not always needed. The patient lies still on the exam table during the scan.

If metal implants are present in the spine, artifacts can obscure nearby areas. Radiologists can usually recognize these artifact patterns when interpreting the study.

Key points

• Useful for complex fractures.
• For nerves and discs, MRI is often more informative.
