A diskogram is a radiographic procedure in which a needle is placed into the discs between the lumbar vertebrae and contrast is injected to diagnose abnormalities in the disc spaces.

How do I prepare for the exam?

On the day of the exam, you can have clear liquids but no other food or drink. Please do not take pain medication the day of the exam, as this could mask symptoms that aid in diagnosis during the exam.

Most patients are admitted through the Admissions and Testing Unit about two hours prior to test time. After you check in, Admissions and Testing staff will prep you for your exam, including checking vital signs, taking any needed laboratory tests, and starting an IV if necessary.

What can I expect during the exam?

The exam is conducted by a neuro-radiologist and a specially trained interventional radiology technologist.

You will be dressed in an open back hospital gown and placed stomach down on the exam table. A numbing agent will be injected at the skin in the area where the injection will be.

You will be fully conscious throughout the exam so you can communicate with the radiologist as needed.

What can I expect after the exam?

After the exam, you should expect a brief period of bed rest. Some pain related to the disc injections may continue for up to two days following the procedure.

Detailed home instructions will be discussed with you at the time of your exam.
