Discogram

Last updated Jan. 18, 2019

This discogram shows a normal disc L4-L5 and degenerated disc L5-S1. Both discs have been injected (by needles inserted from the right) with a contrasting dye pressurized as if the patient were standing. The L4-L5 disc shows clear boundaries, whereas the L5-S1 disc shows cracking and a more spread-out distribution of the dye.


Background Information:

What are the other Names for the Procedure?

  • Disc Stimulation
  • Discography
  • Diskogram

What is Discogram radiology procedure? (General Explanation)

  • A Discogram is an imaging test to detect intervertebral disc problems such as back pain
  • Intervertebral discs are shock absorbers - a cushion-like material between the vertebrae, spine, and bones
  • A bulge of the intervertebral disk may cause pressure on neighboring spinal nerves, resulting in pain

What part of the Body does the Procedure involve?

The Discogram procedure involves the spine.

Why is the Discogram radiology procedure Performed?

A Discogram is used to probe into the cause of back pain and to detect any abnormal intervertebral discs.

What is the Equipment used? (Description of Equipment)

The Discogram procedure includes the following equipment:

  • A radiographic table
  • A computer monitor
  • An examination table
  • A CT scanner
  • An X-ray machine

What are the Recent Advances in the Procedure?

There have been no recent advances to replace the Discogram procedure.

What is the Cost of performing the Discogram radiology procedure?

The cost of a Discogram procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.

In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.

When do you need a Second Opinion, prior to the Procedure?

It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding a Discogram procedure and what needs to be done

If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician

Also, if the procedure involves multiple steps or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently

Prior to Discogram radiology procedure:

How does the Discogram radiology procedure work?

  • X-rays are passed through the patient’s body and recorded on a recording plate on the other side of the body
  • Various parts of the body absorb different amounts of radiation, and these show-up differently in shades of gray or black on the plate
  • Fluoroscopy uses X-ray beams and creates images on the monitor

How is the Discogram radiology procedure Performed?

  • The patient is positioned on the examination table and an intravenous (IV) line is inserted into the vein
  • Their blood pressure, heart rate, and pulse are monitored. The patient is administered local anesthesia
  • A needle is inserted through the skin into the center of the intervertebral disk being examined, using imaging guiding tools
  • The contrast material is injected when the needle reaches the center of the disc; after which, the needle is removed
  • The vertebral disc is examined using real-time imaging produced by fluoroscopy and by taking several images
  • The Discogram procedure may be repeated if more than one intervertebral discs are being examined

Where is the Procedure Performed?

A Discogram is performed as an outpatient procedure at a hospital.

Who Performs the Procedure?

An interventional radiologist performs the Discogram procedure.

How long will the Procedure take?

A Discogram procedure usually takes about 30 minutes.

Who interprets the Result?

An interventional radiologist interprets the results of a Discogram procedure.

What Preparations are needed, prior to the Procedure?

  • It is recommended that mothers breastfeed their children (at least) 24 hours after the contrast material is injected
  • There is a chance of spinal nerve damage, bleeding, or paralysis
  • In some cases, the back pain may worsen after the procedure

What are the Limitations of the Discogram radiology procedure?
