In order to properly diagnose a patient's condition, x-rays are most commonly taken. These x-rays are used to check vertebral alignment, disc degeneration, proper curvature, scoliosis, and other serious pathology. We also use x-rays to document a patient's structural progress as well. With the advancement of high-speed film and limited exposure, the amount of radiation used is far outweighed by the useful information gained by actually seeing the patient's spine.
