Thank you for posting your query.
Certain mesh are MRI-compatible. This information can be obtained from your surgeon.
If the mesh is not comaptible with MRI, then, you should avoid MRI.
In such cases, CT scan
of the back can be done, which can give a lot of valuable information.
Please discuss these issues with your doctor.
Wishing you good health,
Dr Sudhir Kumar MD DM (Neurology)
