Does an MRI show piriformis syndrome?

How is piriformis syndrome diagnosed?

Can piriformis syndrome be seen on xray?

X-rays and other spinal imaging studies cannot detect if the sciatic nerve is being irritated at the piriformis muscle. However, diagnostic tests (such as X-rays, MRI and nerve conduction tests) may be conducted to exclude other conditions that can cause similar symptoms to piriformis syndrome.

What can mimic piriformis syndrome?
