Magnetic Resonance Imaging (MRI) is one form of imaging used by physicians to look inside the human body to obtain clinically useful diagnostic information. Images are formed when signals emitted by body tissue are processed and turned into visual clinical images. 

Digital motion X-ray (DMX) is an X-ray video: many hundreds or even thousands of X-ray images strung together. This technology seems amazing, and maybe it offers some diagnostic hope to people with serious, mysterious chronic pain, especially in the neck and back.
