What is the difference between a DMX and an MRI?
DMX is simply a new type of x-ray system that allows the clinician to take x-rays while the patient moves in a standing weight-bearing position. DMX evaluates the bones in motion allowing us to detect which specific ligaments have been injured. If you hurt more when you move, then you must be diagnosed while you move. MRI of the cervical spine is designed to evaluate disc injuries while not moving, lying down, and not swallowing. The symptoms of a cervical disc injury are usually numbness and tingling in the upper extremities. The upper 30% of the spine and posterior aspect of the spine contain no discs, just ligaments. Headaches and posterior neck pain are commonly caused by stretched ligament injuries which cannot be detected by MRI.
