What does a spine MRI look for?
The MRI lets your doctor examine the small bones, called vertebrae, which make up your spinal column, as well as the spinal disks, spinal canal, and spinal cord. The test looks for: Your doctor may also use a spine MRI to help plan surgeries on the spine, like for a pinched nerve, or for procedures like epidural or steroid shots.
What should I know before getting a lumbar MRI?
Before deciphering the abnormalities listed in the lumbar MRI report, it’s important to understand the normal anatomy. The lumbar spine consists of bones (usually five vertebral bodies) stacked on top of each other and separated by five discs.
What are the most common changes in a lumbar MRI?
Listed are some commonly occurring changes, which may be described in a lumbar MRI report. The most common levels affected at L4-5 and L5-S1 as these are the most mobile levels in the lumbar spine. About 60% of a person’s range of motion is at L4-5 and L5-S1. This term is very broad and can be used to describe any arthritis in the spine.
Should I discuss my MRI report with my spine specialist?
It’s imperative that you discuss the MRI report with a spine specialist to see which, if any, of these findings, are important and need to be addressed. The spine specialist should review the actual images with you and answer any questions you have about your report.

Does a spine MRI show other organs?
Lumbar spine MR imaging may detect abnormalities of the kidneys, adrenal glands, liver, spleen, aorta and para-aortic regions, inferior vena cava, or the uterus and adnexal regions.
What does an abnormal spinal MRI mean?
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 (spondylitis)
Will a pinched nerve show on an MRI?
MRI scans which show soft tissues, such as nerves and discs, are generally preferred over CT scans which show bony elements. Advanced imaging can show exactly which nerve or nerves are being pinched and what is causing the nerve to be pinched.
Can an MRI show nerve damage?
Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings. The MRI scan images are obtained with a magnetic field and radio waves. No harmful ionizing radiation is used.
Does the sciatic nerve show up on an MRI?
The cause of sciatic nerve pain is usually diagnosed using an MRI. Patients are not exposed to radiation. In addition, this procedure causes no pain and requires no recovery time.
Does MRI show inflammation in back?
In comparison, MRI-proven spinal inflammation was found in 70–100% [5, 7, 12, 13, 16] of patients in other studies with patients who had a longer disease duration. Inflammatory oedematous spinal lesions were found in different anatomical structures in this study.
Can a lumbar spine MRI show MS?
Diagnosing MS through spine and brain lesions The most effective and non-invasive way to determine if a person has MS is to scan for brain and spinal cord lesions using magnetic resonance imaging (MRI). Lesions are usually the most telling symptom of an MS diagnosis.
How accurate are MRI scans of the spine?
With many nuances, accuracy relies heavily on the skill of the reading radiologist. In a study published by The Spine Journal, the diagnostic error rate for lumbar MRI interpretations was a striking 43.6 percent.
What does a black disc on MRI mean?
Black disc is used to describe a dehydrated and totally degenerated spinal disc . It derives its name from the way it is seen on an MRI scan as a completely black disc. A normal healthy disc has a white center (nucleus) but as the disc degenerates its turns a darker color on the MRI scan.
What will an MRI show for back pain?
An MRI scan of your back will show images of wear and tear on the spine and other bones of your back, along with muscles, ligaments, and other soft tissues in the area. However, it is normal to see signs of damage to structures and tissues of the back, particularly among older adults.
What is spinal MRI?
A spinal MRI, or magnetic resonance imaging, uses powerful magnets, radio waves, and a computer to make clear, detailed pictures of your spine. The MRI may scan your whole spine or just a part of it.
Why do you need a spine MRI?
Your doctor may also use a spine MRI to help plan surgeries on the spine, like for a pinched nerve, or for procedures like epidural or steroid shots. If you have any of these symptoms, you might need a spinal MRI:
How long does it take to get an MRI of the spine?
MRI scans can take from 30 minutes to an hour or more, depending on how much of your spine is being scanned. After a spine MRI, you can go back to your normal activities right away. But if you had medicine to relax before the test, you’ll need to wait until it wears off. Sometimes contrast dye can cause side effects.
How long does an MRI last?
Often an MRI exam includes a number of runs, or sequences. Each run can last from a few seconds to several minutes. You have to stay very still during each one. The MRI machine creates a strong magnetic field around you. A computer takes the signals from the MRI and uses them to make a series of pictures.
What do you need to remove for an MRI?
You’ll need to remove any eyeglasses , hearing aids, jewelry, your watch, body piercings, dentures, and other metal items. Y our medical team will check to see if any implants or medical devices in your body are compatible with the MRI machine. If you have tattoos or permanent makeup, talk to your doctor.
What are the risks of MRI?
Other risks of MRI include: Claustrophobia. Some people get this from having to go into the MRI tube or tunnel. You can take anti-anxiety medication ahead of the procedure to help with this or try an open MRI machine. Allergic reaction or sensitivity to contrast dye.
Can a radiologist see you during a test?
The doctor may use straps to help keep you in the right position during the test. A radiologist and technologist will be at a computer outside of the room. They can see, hear, and talk to you the whole time. Sometimes a family member or friend can stay in the room with you.
What are the two most common slices that we look at on MRI scans of the spine?
The two most common slices that we look at on MRI scans of the spine are the sagittal and coronal slices. The saggital plane sections the human body lengthwise. The axial plane creates a cross section of the human body.
What is the critical task when it comes to interpreting MRI scans?
Therefore, the critical task when it comes to interpreting MRI scan is CORRELATING the findings on the MRI scan with the patient’s complaints and with the physical exam. What a normal MRI scan looks like. This is an MRI scan of a 40 year old male. There are 5 intervertebral discs in the lumbar spine.
How many intervertebral discs are there in the lumbar spine?
There are 5 intervertebral discs in the lumbar spine. We are going to start with a normal level which has a normal intervertebral disc. Each disc separates two bones called vertebrae in the spine. In this case, this is the L3-4 disc. Above the disc is the L3 vertebral body and below the disc is the L4 vertebral body.
What is the center of the disc called?
When we are young, the center of the disc, called the annulus fibrosis, has an electrical charge that holds onto water very well. The disc is viscous, elastic, and is a good shock absorber. With time, the center of the disk loses water content and the disk starts to “dry out”.
What is the axial plane of MRI?
The axial plane creates a cross section of the human body. An MRI image looks like a photograph, but it is actually a computerized image of the nuclear magnetic resonance of molecules inside the human body. These images are superior to CT scans and X-rays.
What is the fluid in the spinal canal called?
The spinal canal is filled with white fluid, called cerebrospinal fluid (CSF). Inside the CSF is the spinal cord and the nerve root that go down to the legs. On the axial image, the neuroforamen are wide open and there is plenty of space available for the nerve roots. Disc dessication.
What would you see if you looked at the skin of the gentlemen on the right?
If we were to look at the skin of the gentlemen on the right with a microscope, we would see evidence of degeneration, loss of elasticity (which is called elastosis), noncancerous skin growths (called keratoacanthomas), pigment changes such as liver spots, and thickening of the skin.
What are the problems with the lumbar spine?
Problems in the Lumbar Spine. As we get older, changes occur naturally in the spine. The discs tend to lose their water content (desiccate). The annulus of the disc may bulge, protrude or herniate. The bones may develop bone spurs (osteophytes). The ligamentum flavum may enlarge (hypertrophy).
What is the L5-S1 disc?
Therefore the L4 and L5 vertebral bodies are separated by the L4-5 disc. Just below the lumbar spine is the sacrum so the bottom disc is called L5-S1. This normal configuration is reported in the MRI report as both sagittal and axial depictions. The sagittal view is a profile picture. The axial view is a cross-section.
How many vertebrae are in the lumbar spine?
Before deciphering the abnormalities listed in the lumbar MRI report, it’s important to understand the normal anatomy. The lumbar spine consists of bones (usually five vertebral bodies) stacked on top of each other and separated by five discs. The vertebral bodies are usually labeled 1 through 5, and the discs are named by the bones above and below.
What happens to the spine as you get older?
As we get older, we all develop “changes” in our spines. Studies have shown that about 30% of completely pain-free (asymptomatic) people undergoing a lumbar MRI have abnormalities detected. After the age of 60 years old, about 90% of people have at least a “degenerative disc.”. Low back pain is one of the most common diseases in the United States. ...
What happens when the facet joints enlarge?
The facet joints may enlarge (hypertrophy). The bones may slip on one another (subluxation or spondylolisthesis). The result of these changes may narrow the place where the nerve exits the spine (foraminal stenosis). These changes may narrow the canal where the nerves reside in the spine (central stenosis).
Which nerves go to the groin?
The back side of the spine is more bone called the lamina and spinous process. The nerves go to specific regions of the leg. The L1 and L2 nerves tend to go to the groin region. The L3 nerve to the front of the thigh. The L4 nerve to the shin and instep. The L5 nerve to the top of the foot and big toe.
Where does the spinal cord end?
The spinal cord itself ends around the T12-L1 level , but the nerves continue down the lumbar spine as the cauda equina. At each disc level, a nerve exits the spine and goes to a specific region of the leg. The back side of the spine is more bone called the lamina and spinous process.
What is a bulge in the cervical disc?
A normal cervical disc has a smooth concave (arch) shape over the spinal canal. Typically a bulge just means the annulus is weaker and deviates towards the nerve sac. Bulges are extremely common and rarely cause any pain or symptoms. Many people have them at multiple levels in their spine. Protrusion is a slight progression in which the disc now MAY focally direct towards the cord or nerve. An extrusion or herniation occurs when a piece of the nucleus now has exited the disc and is possibly pressing on a nerve or the spinal cord.
Where does the spinal cord go?
Sometimes this measurement is included in a report. The spinal cord itself extends through the entire cervical spine. At each disc level, a nerve exits the spine and goes to a specific region of the arm. Some patients are born with smaller-than-normal cervical canals.
What is the difference between cervical and lumbar spine?
Therefore the cervical spine encases the spinal cord, whereas most of the lumbar spine encases peripheral spinal nerves, called the cauda equina. The normal cervical spine canal should be between 10-14 millimeters. Some report even larger, up to 16 millimeters. Sometimes this measurement is included in a report.
How many discs are there in the cervical spine?
The cervical spine consists of bones (usually 7 vertebral bodies) stacked on top of each other and separated by 6 discs. There is no disc between the first and second cervical vertebrae.
What is the softer part of the cervical disc?
These are microscopic and cannot exactly be differentiated on an MRI. The central softer part of the disc is the nucleus and the out layer is the annulus. Normally, the annulus holds the nucleus in the center and there is no contact with the nerve roots.
What is the difference between axial and sagittal view?
The sagittal view is a profile picture. The axial view is a cross-section. The viewpoint is similar to the lumbar spine. Just behind the column of bones and discs is the sac which holds the spinal cord, nerve roots and fluid, called cerebral spinal fluid (CSF). Now this is different from the lumbar spine.
Can cervical spine degeneration be mistaken for shoulder degeneration?
Cervical spine degeneration can be mistaken with other conditions, like muscle strains or shoulder problems. Not every patient experiences the same symptoms or signs, so evaluating your individual condition may best be achieved by talking to a specialist, and not just comparing complaints with a friend or family.
What are the symptoms of a lumbar MRI?
A doctor may order a lumbar MRI if a person has any of the following symptoms: sudden back pain that occurs alongside fever. injury or trauma to the lower spine. severe and persistent lower back pain. multiple sclerosis. leg pain that suggests a lumbar disc herniation. bowel or bladder incontinence.
What is a lumbar MRI?
A lumbar MRI is a powerful diagnostic tool that doctors may use to: check spinal alignments. detect abnormalities of vertebrae or the spinal cord. evaluate any inflammation of the spinal cord or nerves. check for tumors on or around the spinal cord. monitor damage to the spine after an injury.
Why do doctors do lumbar MRIs?
Medical professionals perform lumbar MRIs for a variety of reasons. If someone is experiencing pain in their lower back, a doctor may recommend a lumbar MRI scan to help diagnose the source of the pain. A doctor may also order a lumbar MRI for a person who is about to undergo back surgery. In this case, the surgical team uses the results ...
How does an MRI work?
The MRI machine uses a strong magnetic field that aligns and stimulates particles called protons in the body, for cing them to spin out of alignment. When the technician halts the magnetic field, the protons begin to spin in their usual way. As they do this, they give off energy that the MRI machine detects.
What is the purpose of contrast dye in MRI?
MRI technicians sometimes also use gadolinium, which is a type of contrast dye, to help enhance the quality of the images that the MRI scan produces. They inject the contrast dye through an intravenous line into a vein in either the hand or the arm of the person.
Why is it important to remove metal before an MRI?
Again, because the MRI machine emits a strong magnetic field, it can cause metal implants inside the body to move.
What is magnetic resonance imaging?
Magnetic resonance imaging is a noninvasive diagnostic tool that uses radio waves and a magnetic field to produce detailed images of the inside of a body. Doctors can use them to examine a person’s lower spine, or lumbar region, and the surrounding tissues. The exam itself is very safe because it does not use ionizing radiation, ...
What is MRI for arthritis?
There are two main types of arthritis: osteoarthritis (OA) and rheumatoid arthritis (RA).
What to expect before scheduling an MRI?
Before scheduling an MRI, your doctor will first review your symptoms and ask: Your doctor will also perform a physical examination and look for the following: In addition to your physical exam, there are common tests, including an MRI, that your doctor may request. These include:
What will your doctor tell you about osteoarthritis?
Your doctor will also inform you of the severity or stage of the osteoarthritis. An orthopedist may also see another condition on the MRI, such as a muscle strain or cartilage tear. Based on the holistic review of your condition and MRI results, your doctor will give you an appropriate treatment plan.
What is the grating sound when you move the joint called?
thinning of the muscles. reduced movement in the joint. tenderness of the joint. grating sounds when you move the joint, called crepitus. swelling in the bone. instability in the joint. stiffness. In addition to your physical exam, there are common tests, including an MRI, that your doctor may request. These include:
Can you get a blood test for osteoarthritis?
Blood tests: There is no blood test for osteoarthritis. However, your doctor may use it to rule out other possible diagnoses. Joint fluid analysis: If there is significant swelling around the joint, a doctor may use a needle to withdraw fluid and test the sample for possible gout, infection, or osteoarthritic-related inflammation.
Is X-ray good for osteoarthritis?
These include: X-rays: Like MRIs, these images are also good at discovering common features of osteoarthritis including bony spurs, narrowing of the space between bones, and possible calcium deposits. X-rays are less expensive than MRIs, and the results are usually obtained more quickly.
Introduction
Function
- Magnetic Resonance Imaging creates thin section images of the inside of the human body. This technique allows us to visualize anatomic structures from any angle and direction. The two most common slices that we look at on MRI scans of the spine are the sagittal and coronal slices. The saggital plane sections the human body lengthwise. The axial pla...
Diagnosis
- Every MRI scan after the age of 30 is abnormal By the time that a patient sees me, they usually have had the opportunity to read their own MRI report which typically sounds something like: While there is a healthy debate about what constitutes an abnormal versus a normal MRI scan of the spine, there are a few key findings that reveal a problem that we know will require surgery. I s…
Significance
- These two pictures explain why. The natural aging process causes changes to every structure of the human body. The spine is no different. If we were to look at the skin of the gentlemen on the right with a microscope, we would see evidence of degeneration, loss of elasticity (which is called elastosis), noncancerous skin growths (called keratoacanthomas), pigment changes such as liv…
Symptoms
- However, we could describe the skin on the right as normal for age. We only describe it as abnormal when we compare it to the image of the baby on the left. Most people, even if they dont have any back pain, will still have evidence of abnormalities on MRI scans. Disc degeneration, bulging disks, and herniated discs occur very commonly and they may not be causing symptom…
Quotes
- When we are young, the center of the disc, called the annulus fibrosis, has an electrical charge that holds onto water very well. The disc is viscous, elastic, and is a good shock absorber. With time, the center of the disk loses water content and the disk starts to dry out. I tell patients that all of our intervertebral discs start out as fat plump grapes and eventually end up like raisins. Just li…
Causes
- Disc degeneration is a more advanced form of disc dessication. In addition to the nucleus pulposus drying out, the disc starts to collapse. Bone spurs form around the edges of the intervertebral disc. Disc degeneration is the same thing as degenerative arthritis. This condition is inevitable. Its just as certain as death and taxes, and it will happen to everyone if they live long e…
Example
- In contrast, this example shows a really large disc herniation. In this case, the nucleus pulposus has herniated completely through the annulus and there is a large free fragment of disc material filling the neural foramen and completely obstructing the normal path for the exiting and traversing nerve roots.
Results
- The end result of all of these changes is spinal stenosis. Stenosis mean narrowing. The process of disc bulging, degenerative disc disease, and the development of arthritis of the spine all cause narrowing of the space available for the nerve roots. Here is a short video where I review the MRI scan of someone with two level severe spinal stenosis and illustrates this process.
Risks
- Recently, it has become much more common to give the patient a copy of the MRI and report from the radiologist. Unfortunately, this often creates a lot of confusion and concern. However, the opposite is also true. If you MRI scan shows that you have a large disk herniation, a free fragment, severe neuroforaminal narrowing, severe spinal stenosis, or a severe spondylolisthesis, chance…
