What is an epidurography?

Epidurography is a medical imaging technique used to visualize the epidural space in the spine. It involves the injection of a contrast dye into the epidural space, typically under fluoroscopic guidance, allowing for detailed imaging of the structures and any potential abnormalities. This procedure can help diagnose conditions such as spinal stenosis, herniated discs, or epidural abscesses. It is often used in conjunction with other diagnostic tools to guide treatment decisions.
