    "description": "A short plain-film study of the lower back, usually a front and a side picture and sometimes a third angle, covering the lumbar vertebrae and often the sacrum where the spine meets the pelvis. It shows alignment, disc space height, arthritic change, and vertebral fractures, but not discs or nerves themselves, which need MRI. A larger lumbar study exists for when oblique or bending views are also required.",
