Is an MRI or CT Scan Better for a Herniated Disc?

Both MRI and CT scans are advanced diagnostic tools. MRI is usually the first choice for a suspected herniated disc because it captures soft tissue in exceptional detail and uses no radiation. CT is often a better option when your doctor needs a closer look at bone or when an implant or medical device makes MRI less suitable for you.

What Does a Herniated Disc Look Like on an MRI?

On an MRI, a herniated disc looks like part of the disc is pushing beyond where it normally sits. The affected disc also usually looks darker than a healthy one because it has lost water content.

How Do You Get a Herniated Disc Diagnosis?

Getting a herniated disc diagnosis usually starts with a physical exam. Your doctor will review your symptoms and medical history and may check your reflexes, muscle strength and sensation. If your symptoms don't improve with rest and physical therapy after a few weeks, or if you have severe weakness or numbness, your doctor may order an MRI or other imaging exam to take a closer look at the disc and nearby nerves and confirm the diagnosis.

How Long Does a Herniated Disc MRI Take?

A spine MRI generally takes 15 to 45 minutes of scan time, depending on how much of the spine your doctor needs to see. Plan accordingly to allow time for check-in and screening as well. American Health Imaging's faster scanning MRI technology reduces many scan times to as little as 8 minutes, and our technologists talk with you throughout the scan so you always know how much longer you'll be in the scanner.

Is Imaging for a Herniated Disc Painful?

MRI, CT and X-ray exams are painless. A myelogram involves a thin needle, but the area is numbed first to keep you comfortable. During an MRI, CT or X-ray, you'll lie still on a table while the images are captured, and many of our locations let you listen to music during your scan to help pass the time.

Where Are American Health Imaging Centers Located?

MRI is available at every American Health Imaging center, with locations throughout Alabama, Georgia, Tallahassee, FL, Beaumont, TX, San Antonio, TX and South Carolina. Digital X-ray is offered at select centers in Alabama, Georgia and Texas, and myelograms are performed at select centers in metro Atlanta and Birmingham. Because services vary by site, call the center nearest you to confirm which exams are available before you schedule.
