MRI Lumbosacral Spine

Also known as Lumbar MRI scan, MRI of the lumbar spine, MRI of the spine

This test is for

Male, Female

Test Preparation

At the time of the MRI you might be asked to remove any metallic coins, jewelry, metal wrist watches, metallic keys, dentures or hearing aids as the MRI uses strong magnetic fields.
Tell your radiologist if you have metallic implants like pacemaker, cochlear implants, aneurysm clips, neuro-stimulator, surgical staples/clips or drug implants.
Pregnant women should inform their doctor about their pregnancy before going for MRI.

Understanding MRI Lumbosacral Spine

What is MRI Lumbosacral Spine?

The Magnetic Resonance Imaging (MRI) Lumbosacral Spine test is a highly advanced, noninvasive, painless imaging technique that provides detailed cross-sectional images of the lower part of the spine (lumbar spine). It helps doctors to diagnose lower back pain, plan back surgery, or monitor progressive medical conditions.

The MRI Lumbosacral Spine test provides detailed cross-sectional images of the spine that help doctors identify the root cause of lower back pain or discomfort. It is used to examine the lower back region, including the bones, discs, nerves, and soft tissues. It helps doctors detect spine-related issues like herniated discs, nerve compression, and spinal injuries. It is also useful in detecting more serious conditions like tumors or inflammation in the spine. This test utilizes advanced magnetic resonance technology in either open MRI (less confining) or closed MRI (high resolution) systems to provide precise imaging of the lumbar spine (lower back).

The MRI of the lumbar spine is recommended when the individual experiences persistent lower back pain, numbness, or weakness in the legs, especially if these symptoms don't improve with the initial line of treatment. It is also advised if the doctor suspects problems like herniated discs, nerve compression, spinal injury, or degenerative conditions. Additionally, this test checks for infections, tumors, or any structural abnormalities in the spine that may be causing the discomfort.

Before undergoing the MRI Lumbosacral Spine test, remove metal objects like metallic coins, jewelry, metal wristwatches, metallic keys, dentures, or hearing aids, as the MRI uses strong magnetic fields and can pull on any metallic objects. Wear loose and comfortable clothing without metal fasteners. Inform the doctor about any pregnancy, medical history, allergies, medications, pacemaker, metal implants, etc. before going for an MRI test. If too claustrophobic or overweight to undergo a traditional closed MRI, discuss open MRI options with the doctor.

Interpretation of test results requires expert guidance. Therefore, do not self-medicate solely based on these test results. Always consult the doctor for proper understanding of the test results. By providing comprehensive insights into the structure and function of the lumbosacral area, this test helps in the precise diagnosis and helps guide targeted treatment plans.

What is MRI Lumbosacral Spine used for?

The MRI Lumbosacral Spine test is done:

To investigate the cause of lower back pain.
To check for a slipped or damaged disc.
To check for compression of the nerves in the lower back region.
To detect injuries like fractures or tears of the tissues after a trauma.
To look for signs of arthritis or other spine problems.
To check for spinal tumors or abnormal masses.
To spot infections or swelling in the spine.
To check for any congenital spinal problems.

What does MRI Lumbosacral Spine measure?

Magnetic resonance imaging (MRI) is an imaging procedure that uses a combination of a large magnet, radio frequencies, and a computer to produce detailed images of organs and structures within the body. The MRI Lumbosacral Spine test tells about the detailed structure of the lower back, focusing on the bones, discs, nerves, and surrounding tissues. It provides cross-sectional images of the lower back that help doctors assess the alignment of the spine, and detect any issues like herniated discs, compressed nerves, or signs of degeneration. The test can also reveal any inflammation, infections, tumors, or injuries in the spine, helping diagnose the source of pain or discomfort and guide care strategies.

Answers to Patient Concerns & Frequently Asked Questions (FAQs) about MRI Lumbosacral Spine

Frequently Asked Questions about MRI Lumbosacral Spine

Q. Is the MRI Lumbosacral Spine test safe?

Yes, the MRI Lumbosacral Spine is considered safe for most individuals. It doesn’t use ionizing radiation, but if you have metal implants or are pregnant, discuss it with your doctor before undertaking this test.

Q. How long does the MRI Lumbosacral Spine test take?

The MRI Lumbosacral Spine test may last as long as it takes for the radiologist to get clear images of the intended areas.

Q. Why might I need the MRI Lumbosacral Spine test?

Your doctor may recommend the MRI of the lumbosacral area to evaluate symptoms such as persistent back pain, leg pain, numbness, and weakness, or to assess conditions like sciatica.

Q. What should I expect during the MRI?

During the MRI, you will lie on a table that slides into the MRI machine. The procedure is painless, but you may need to lie still for some time while images are taken. You may hear loud tapping or thumping sounds.

Q. Will I feel any pain during the MRI Lumbosacral Spine test?

An MRI exam causes no pain. You will need to lie still, as too much movement can blur MRI images and cause errors.

Q. Do I need a doctor's prescription for the MRI Lumbosacral Spine test?

Yes, a doctor's prescription is typically required.

Q. Can I bring a family member or friend with me during the MRI Lumbosacral Spine test?

Policies may vary across diagnostic centers. However, usually a family member can stay in the waiting area during the procedure.

Q. What if I’m claustrophobic?

If you have claustrophobia, inform your doctor or technician before the test. They may suggest solutions like medication or sedation to help you relax, or they might use an open MRI machine, which provides a less confined space.

Q. What is the difference between open and closed MRI?

Open MRI machines have a wider opening and are less confining. This makes them ideal for claustrophobic individuals. Closed MRI machines have a narrow design and usually provide higher-resolution images, which can be better for detailed examinations. The choice depends on medical needs and individual comfort.

Q. Can I have an MRI if I’m pregnant?

MRI is generally considered safe during pregnancy as it uses radio waves and magnetic fields to create images and does not use radiation.

Q. What if I have metal implants or devices?

Inform your doctor about any implants, pacemakers, or any metallic devices, as the MRI uses strong magnetic fields and can pull on any metallic objects.
