Weight Bearing MRI

What Is a Weight Bearing MRI?

A Weight Bearing MRI, also known as an Axial-Loaded MRI, captures images of the spine while it is under the compressive forces experienced in an upright position. Traditional MRI scans are performed with the patient lying flat, which can relieve spinal pressure and potentially mask certain conditions.

Why Is It Important?

Many spinal conditions — including disc herniations, spinal stenosis, and instability — are more pronounced when the spine is bearing weight. This scan reveals problems that would otherwise go undetected on a conventional MRI.

Conditions Diagnosed

• Lumbar spinal stenosis
• Disc herniation and bulging discs under axial load
• Spondylolisthesis (vertebral slippage)
• Degenerative disc disease under load
• Facet joint arthritis and instability

Who Should Consider This Scan?

Patients who have back or neck pain that worsens when standing or walking, but whose standard MRI results appear normal, are ideal candidates for a Weight Bearing MRI. This scan provides a functional, real-world picture of spinal anatomy under stress.
