Diskography is an imaging test. It involves injecting a contrast material into a disk in the spine and taking an x-ray. An x-ray is a test that uses radiation to take a picture of structures inside the body. The contrast material helps the disk appear more clearly on the x-ray.
Herniated Lumbar Disk

This test is used to detect if a herniated disk or otherwise abnormal disc is a source of pain. Disks are small, circular cushions between the vertebrae (bones) in the spine. A herniated disc occurs when a disk in the spine bulges from its proper place. Herniated disks can press on the nerves and cause severe pain. In some cases, they can cause pain themselves, but often an abnormal disc is not painful.
