Description
MRI can detect a variety of conditions of the lumbar spine, including problems with the bones (vertebrae), soft tissues (such as the spinal cord), nerves, and disks. An MRI sometimes is performed to assess the anatomy of the lumbar spine, to help plan surgery on the spine, or to monitor changes in the spine after an operation. For example, it can find areas of the spine where the spinal canal (which contains the spinal cord) is abnormally narrowed and might require surgery. It can assess the disks to see whether they are bulging, ruptured, or pressing on the spinal cord or nerves. MRI of the lumbar spine can be useful in evaluating symptoms such as lower back pain, leg pain, numbness, tingling or weakness, or problems with bladder and bowel control. It can also help to diagnose tumors, bleeding, swelling, developmental or structural abnormalities, and infections or inflammatory conditions in the vertebrae or surrounding tissues.
