Visualization Of The Effects Of Gravity On The Intervertebral Discs In A True Physiological Upright Weight-Bearing MRI Scan
The recumbent image shows degenerative disc disease at L4/5 and L5/S1 manifest as a loss in hydration but fails to show the loss in disc height at L4/5 and L5/S1 and the segmental instability (anterolisthesis) that accompanies it. The upright image shows degenerative intersegmental hypermobile instability (anterolisthesis: arrows) at L4/5 and L5/S1. L4/5 and L5/S1 exhibits narrowing of the disc spaces in the upright weight-bearing position.
