Weight-bearing MRI (for Lumbar Central Spinal Stenosis)

Most patients experience back or neck pain while sitting or standing, and lie down to relieve their pain. Traditional MRIs examine patients while lying down…in the position least likely to show the source of their pain.

At Swift Imaging we use a Stress Test MRI to examine the spine in both supine (lying down) and while bearing weight (sitting or standing). This allows doctors to observe how a patient’s bodyweight applies pressure to the injured discs, pinching the nerves and causing pain.

The unique Esaote Tiltable MRI obtains images in both the traditional horizontal position and tilts to an upright position during the same examination.

The Stress Test MRI explains why patients hurt standing up, but feel relief lying down, and why conventional MRI exams may fail to reveal the problem.

The Stress Test MRI used to examine the lumbar spine visualizes the anatomy in both supine and weight-bearing positions, and shows increased pressure applied to the spine while standing.

When the patient is lying down during a traditional supine MRI examination, stresses on the discs are slight or non-existent, and space for the nerves is increased within the spinal canal.

When the table is tilted upright, the discs expand, the bones slip forward, ligaments buckle, and the space available for the nerves is decreased. This condition – called spinal stenosis – is best evaluated when the patient is standing-up (or bearing weight).

Supine images frequently fail to document spinal stenosis, while MRIs taken in weight-bearing position show the source of the pain.

A Stress Test MRI helps doctors at Swift Imaging diagnose and understand positional symptoms, which often affect the patient only when sitting or standing. While patients may experience relief while lying down…pain, numbness or weakness typically increase as the patient moves into an upright or weight-bearing position.

Diagnostic, weight-bearing images can reveal pinched nerves or injured discs that explain a patient’s symptoms, and which may not be seen in traditional supine images. In fact, conventional supine MRIs can miss thirty percent of spinal injuries.

If you experience more pain or numbness when you are standing or sitting, insist on a Stress Test MRI today. It’s your MRI – don’t take it lying down.
