Axial Loading of the Lumbar Spine
Pacific Imaging Center takes pride in providing access to the latest advances in medical imaging. We are currently the only facility in Cowlitz County to offer the DynaWell® L-Spine device.

The DynaWell® L-Spine simulates axial compression while standing, offers a higher resolution alternative to stand-up MRI, and can be used in conjunction with our GE 1.5 Tesla EchoSpeed Plus MRI System. Press play below to watch a video demonstration.

The Value of Axial Loading
DynaWell® L-Spine grew out of a need to scan spine disorders and lower back problems with greater accuracy. Designed for use on CT or MRI scanners, it simulates the axial compression on a patient’s spine when standing. The optimal way for a patient with back pain to be diagnosed is in an erect position with the normal gravitational pressure exerted on the spine. This is impractical, however, since it would require the patient to remain upright and motionless for 30 to 40 minutes. Problems that would ordinarily remain undetected when the patient’s spine is relaxed are likely to be more visible with the use of this unit.

The DynaWell device is used with a high-field magnet, as opposed to the low-field upright units that are most commonly found on the market today, resulting in a more precise image of the back.

Published studies, as well as ongoing research, verify that the DynaWell methodology is valuable in lumbar spine pathology (spinal stenosis, sciatica, disc herniation, synovial cysts) and hip, knee and ankle pathology. With DynaWell, clinical studies show that it is possible to achieve a more specific and valid diagnosis, compared with regular non-loaded images. DynaWell has received FDA Approval and CE Certification.

For Patients
DynaWell L-Spine loaded lumbar imaging is comfortable and may result in an earlier and more valid diagnosis, allowing physicians to treat their spinal disorder and helping them to return to a pain-free lifestyle.

As with an ordinary MRI scan, the patient is asked to lie on a flat table. The patient wears the DynaWell L-Spine vest over his or her shoulders and upper chest. The straps on the vest are tightened over the patient’s chest and the patient’s feet are placed against the footplate of the compression device. Two adjustable cords on opposite sides of the vest are attached to the medical compression device.

By tightening the cords to a desired and measured load (up to 50 percent of body weight), it is possible to compress the spinal cord in a way that is similar to that of upright posture. The DynaWell L-Spine compression device helps patients remain motionless and distributes the pressure across the chest rather than the shoulders.
