What is the best imaging for sciatica?

An X-ray of the spine may reveal an overgrowth of bone that can be pressing on a nerve. MRI . This procedure uses a powerful magnet and radio waves to produce cross-sectional images of the back. An MRI produces detailed images of bone and soft tissues, so herniated disks and pinched nerves show on the scan.

Do pinched nerves show up on MRI?

MRI. MRIs create images using a radiofrequency magnetic field, a technique that clearly shows pinched nerves, disc disease, and inflammation or infections in the spinal tissues. MRI is usually the preferred imaging for pinched nerves.

Does sciatic nerve damage show on MRI?

In addition to clearly visualising the lesion, CT and MRI also show in detail its relation to the sciatic nerve (Figure 13).

How does a doctor confirm sciatica?
