Spine MRI Guide: Understanding Your MRI Report
A spine MRI guide starts with one point: most words on your report describe wear, narrowing or pressure somewhere in the spine. Many of those findings are common and don’t mean you need surgery. What they mean for you depends on whether they match your symptoms and your neurological exam.
What to Know Before You Read Your Report
A radiologist writes the report after looking at the images, usually without examining you. That’s why the same finding can be important for one person and harmless for another. Keep these points in mind as you read.
- Disc bulges, disc wear and mild narrowing show up on many MRIs, including in people with no pain at all, and they become more common with age.
- The words mild, moderate and severe describe how a spot looks on the images, not how much pain it should cause.
- A finding matters most when its location lines up with where you feel pain, numbness or weakness.
- Your history and neurological exam carry as much weight as the images when deciding on treatment.
- An abnormal MRI is not, by itself, a reason for surgery. Dr. Zahos starts with non-surgical care when it fits.
Disc Terms on a Spine MRI Report
The discs sit between the bones of the spine. Each has a tough outer ring and a softer center. Reports describe how far a disc reaches past its normal edge and how wide that area is.
Disc Bulge
The disc extends a little past the edge of the bone over a broad area, a bit like a tire that’s low on air. Bulges are very common and often cause no symptoms.
Herniation, Protrusion and Extrusion
A herniation means some disc material has pushed out over a smaller, more focused area. A protrusion is a herniation where the base is wider than the part that sticks out. An extrusion reaches out further, and the part that sticks out is wider than its base. A sequestered fragment has broken away from the disc. When a herniation fits your arm or leg symptoms, herniated disc treatment usually begins without surgery.
Stenosis, Foraminal Narrowing and Nerve Contact
Stenosis means narrowing. Central canal stenosis is narrowing of the main channel that holds the spinal cord or the nerves in the lower back. It often comes from a mix of disc bulging, thickened ligaments and arthritis of the small joints in the back of the spine. When it affects walking or causes leg symptoms, treatment for spinal stenosis depends on how much it limits your day.
Foraminal narrowing refers to the openings on each side of the spine where a nerve root exits. When one of these openings narrows, the nerve passing through it has less room, which can be one cause of pain or tingling that travels into an arm or leg.
Reports also use a range of words for how a disc or bone spur relates to a nerve. Contact usually means the two are touching. Displacement means the nerve is pushed out of its normal path. Compression means the nerve is being pressed. Contact alone is a common finding. Compression is more likely to matter, but only if the nerve involved matches the area where you have symptoms.
Desiccation, Disc Degeneration and Slipped Vertebrae
Many reports describe changes that come with age and use.
Desiccation and Degenerative Disc Disease
Desiccation means a disc has lost some of its water and looks darker on certain images. Loss of disc height often comes with it. Together these are often called degenerative disc disease, but the word disease can be misleading. These changes are common as we get older, and many people with them have no back pain. When a worn disc does seem to be the source of pain, degenerative disc disease treatment focuses on your symptoms, not the picture alone.
Spondylolisthesis
Spondylolisthesis means one vertebra has slipped forward over the one below it. Reports often grade it by how far it has moved. An MRI is taken lying down, so X-rays taken standing or bending may be used to check whether the segment moves. That question of stability shapes treatment for spondylolisthesis.
Spinal Cord Compression and Signal Change
Some findings involve the spinal cord itself, most often in the neck. Cord compression means narrowing has reached the point where the cord is being pressed. Signal change means an area inside the cord looks different from normal on certain images, which can point to irritation or injury of the cord.
These findings deserve a careful look even when pain is mild. Pressure on the cord can show up as clumsy hands, trouble with buttons or handwriting, balance problems or changes in walking. When the exam confirms those signs, cervical myelopathy treatment is about protecting how the cord works, not only easing pain.
Why Your Spine MRI Has to Match Your Symptoms
An MRI shows structure. It can’t tell on its own which finding, if any, is causing your pain. Two people can have nearly identical reports while one feels fine and the other can barely sit.
That’s why Dr. Peter A. Zahos looks at your symptoms, your neurological exam and your imaging together. He checks strength, reflexes and sensation, then compares what he finds with the levels and nerves named on the report. When MRI, CT, X-ray or EMG and nerve conduction results are relevant, he reviews them too.
Our approach starts with non-surgical care, and surgery comes up only when it’s truly needed. In their reviews, patients often mention how clearly he explains their MRI findings.
Serving Paramus and Bergen County
Ridgewood, Englewood, River Edge, Maywood and towns across Bergen County are a short drive from our office at 140 Route 17 North in Paramus. Patients also come to us from other parts of New Jersey and New York with an MRI in hand and questions about what it means.
If you’re looking for a spine surgeon in Paramus, NJ to explain your imaging, bring your images and report to your visit. If another doctor has already recommended an operation, a second opinion on spine surgery in Paramus can show whether your MRI findings support that plan.
Spine MRI Questions From Patients Near You
Is a disc bulge the same thing as a herniated disc?
No. A bulge spreads over a wide area of the disc’s edge and is very common. A herniation is more focused, with disc material pushing out further in one spot. Either one matters only if it lines up with your symptoms.
My report says severe stenosis. Does that mean I need surgery?
Not necessarily. Severe describes how narrow the space looks on the images. Treatment depends on how your symptoms affect your life, what your exam shows and what you’ve already tried.
Why does my MRI list problems at levels that don’t hurt?
Radiologists describe every level they see, and wear at several levels is common. Part of an evaluation is figuring out which finding, if any, explains your symptoms and which ones are simply there.
Should I bring the MRI images or just the written report?
Both, if you can. The report is a summary, and Dr. Zahos prefers to look at the actual images himself. A disc from the imaging center or access to the online images works well.
Can Dr. Zahos review an MRI another doctor ordered?
Yes. Imaging review is a regular part of our evaluations and second opinions. Call our office and we’ll tell you what to send ahead of your visit.
Which symptoms mean I shouldn’t wait for an appointment?
New loss of bladder or bowel control, numbness in the groin or inner thighs, or weakness that’s getting worse quickly need emergency care right away. Go to the nearest emergency room or call 911.
