Stress Test MRI: “Worth Weighting For”
The spine is similar to tires on your car: All tires appear normal when the car is on the rack and there is no weight on the tire. It is only when the weight of the car is paced on the tries that the tires appear flat.
The intervertebral discs of the spine are the same. Most conventional MRI examinations are performed with the patient supine with no weight-applied to the disc and the disc often appears normal (similar to the deflated tire with the car on the rack). In both the supine MRI and the tire on the rack, the test is a falsely negative test where the test appears normal but because no physiologic loading is applied to the spine during conventional non-weight-bearing supine imaging.
Stress Test MRI(TM) is a unique physiologic testing of the spine using a special type of Tiltable MRI(TM) that examines the spine while sitting or standing during physiologic loading conditions and during supine non-weight-bearing conditions. Just as with the auto tire, abnormalities are demonstrated only during weight-bearing approximately 30-40% of the time and explain why the patient has symptoms while standing and yet the conventional MRI was normal or failed to explain the positional symptoms.
If your patient reports symptoms that are worse when bearing weight and the insurance company will authorize only one diagnostic test after radiographs, then the most sensitive and accurate test Stress Test MRI(TM) using a TiltableMRI(TM). It is accurately treat an abnormality if the conventional supine MRI fails to shows it.
