What is the difference between X-ray and magnetic resonance imaging (MRI)?

X-rays visualize the alignment of the spine, whether there is misalignment, degeneration, bone spurs or other problems while MRI shows whether the disc is protruding, the water content of the cartilage and whether there is loss or shedding of cartilage, as well as whether the muscles are torn and the ligaments are damaged, etc. MRI can also be used to assess the degree of nerve compression and to confirm the case of a herniated disc.
