A lumbar spine MRI is a diagnostic imaging test that provides detailed images of the lower back region. It is used to evaluate various conditions affecting the lumbar spine such as herniated discs, spinal stenosis, degenerative disc disease, and tumors.
During the procedure, the patient lies on a table which slides into a cylindrical machine that contains a strong magnet. The machine uses a combination of magnetic fields and radio waves to generate clear and high-resolution images of the spine. The patient needs to remain still during the scan to ensure accurate results.
The images produced by the MRI can help doctors identify the cause of back pain, numbness, or weakness in the lower back and determine the most appropriate treatment plan. It can show abnormalities in the spinal discs, nerves, muscles, and bones. In some cases, a contrast dye may be injected into a vein to enhance the visibility of certain structures.
A lumbar spine MRI is considered a safe procedure and does not involve exposure to radiation. However, individuals with certain medical conditions such as pacemakers or metal implants may not be suitable for an MRI due to the strong magnetic field involved.
Overall, a lumbar spine MRI is a valuable tool in diagnosing and assessing conditions affecting the lower back. It offers detailed and accurate images, aiding healthcare professionals in determining the cause of symptoms and recommending appropriate treatment options.
What will an MRI show for back pain?
An MRI can find tumours, damage to bones and nerves, and narrowing of the spinal canal that pushes on the spinal cord. The test can also show if a herniated disc is putting pressure on nerves.
How do you read a lower back MRI?
What is an abnormal lumbar MRI?
What Abnormal Results Mean. Most of the time, abnormal results are due to: Herniated or “slipped” disk (lumbar radiculopathy) Narrowing of the spinal column (spinal stenosis) Abnormal wearing on the bones and cartilage in the spine (lumbar spondylosis)
How long does a lumbar spine MRI take?
Usually, a lumbar spine MRI takes about 30 to 60 minutes, including the time it takes to get in position. The exam is painless, but most MRI machines require you to be in an enclosed space. If you anticipate having anxiety, your doctor may be able to prescribe an anti-anxiety medication to take on the day of the exam.
