PATIENT EDUCATION
An MRI report can contain unfamiliar terms that sound more alarming than they may be in context.
The report describes anatomy and imaging findings. It does not automatically tell us which finding is causing symptoms, how long a finding has been present, whether it was caused by a particular event, or what treatment you need.
The useful next step is to compare the MRI with your history, symptom pattern, examination, neurologic findings, function, and the clinical question that led to the study.
THE MOST IMPORTANT IDEA
MRI is very useful for showing spinal anatomy, including discs, nerve roots, the spinal cord, soft tissues, and other structures.
But an image is still one part of the clinical picture. A finding can be real on MRI without being the main reason someone hurts.
That is why we ask whether the location and type of finding make sense with the symptoms, examination, neurologic pattern, and functional limitations.
Clinical correlation matters.
The question is not simply “Is something abnormal?” It is “Does this finding help explain what is happening with this patient?”
READING THE REPORT
A useful way to read a spine MRI report is to slow the language down and identify what is actually being described.
For each important finding, we want to know the structure involved, the spinal level, whether the finding is central or more toward one side, whether a nerve root or the spinal cord is affected, and whether the finding matches the clinical pattern.
Words such as “mild,” “moderate,” “severe,” “degenerative,” “bulging,” or “stenotic” describe features of the image. They still need to be interpreted in the context of the patient.
COMMON MRI TERMS
These definitions describe the imaging language. They do not automatically determine whether the finding is symptomatic or what treatment is appropriate.
DEGENERATION
A broad description that may include disc desiccation, disc-space narrowing, bulging, fissuring, osteophytes, end-plate changes, or other age- and wear-related morphology. The term does not tell us by itself whether the finding is painful.
DISC BULGE
A disc bulge is a broad extension of the outer disc contour. In accepted lumbar disc nomenclature, a bulge is not the same thing as a focal disc herniation.
DISC HERNIATION
Herniation refers to a localized or focal displacement of disc material beyond the normal disc space. The morphology can be further described as a protrusion, extrusion, sequestration, or migration.
ANNULAR FISSURE
“Annular fissure” is the preferred imaging term. The finding does not, by itself, prove that the disc was traumatically torn, establish when it occurred, or show that it is the source of symptoms.
STENOSIS
Stenosis describes narrowing. Its clinical importance depends on where the narrowing is located and whether it matches symptoms, neurologic findings, and function.
SPONDYLOLISTHESIS
Spondylolisthesis describes one vertebral segment being translated relative to the adjacent segment. The presence of a “slip” does not automatically mean the segment is clinically unstable.
DISC BULGE VS. HERNIATION
Accepted lumbar disc nomenclature separates a broad disc bulge from a more focal disc herniation.
A herniation may then be described more specifically. A protrusion and an extrusion are defined by the shape and relationship of the displaced disc material to its base. Sequestration means the displaced fragment has completely lost continuity with the disc of origin, while migration describes displaced material that has moved away from the site of extrusion.
Those words describe morphology. They do not tell us by themselves how severe a patient’s symptoms should be, whether the finding is traumatic, or whether a procedure is needed.
Disc Bulge & Herniation →The name describes the shape—not the entire clinical meaning.
Disc terminology is most useful when the imaging level and side fit the patient’s symptoms and examination.
ANNULAR FISSURE
An annular fissure describes separation within fibers of the annulus, the outer portion of a spinal disc.
In accepted disc nomenclature, “fissure” is preferred over “tear” when describing the imaging finding because the MRI appearance alone does not establish that a sudden injury caused it.
The finding also does not automatically establish that the disc is painful or that treatment is required.
Imaging morphology and causation are separate questions. If an accident or other event is involved, timing, prior history, symptom onset, examination findings, prior imaging, and other evidence matter.
STENOSIS & NERVE-RELATED FINDINGS
MRI may describe narrowing around the spinal canal or around the openings where nerve roots travel.
The important question is whether the level and side of the narrowing fit the patient’s symptoms and neurologic examination.
For example, arm or leg pain, numbness, tingling, weakness, reflex changes, or reduced walking tolerance may make a narrowing finding more clinically relevant when the pattern is anatomically consistent.
DEGENERATIVE FINDINGS
Degenerative changes can include disc desiccation, disc-space narrowing, bulging, fissuring, osteophytes, end-plate changes, and other structural findings.
Those findings should not be dismissed, but they also should not automatically be treated as the pain generator simply because they appear on the report.
The clinical significance depends on whether the MRI finding fits the patient’s history, symptoms, examination findings, neurologic pattern, and function.
Degenerative Disc Disease →An abnormal MRI does not automatically equal an abnormal patient.
Imaging findings should be weighed against how the person is actually functioning and what the examination shows.
WHAT AN MRI CANNOT TELL US BY ITSELF
A single MRI can provide excellent anatomic information, but several important clinical questions require more than the image alone.
AFTER AN ACCIDENT
Not by itself.
Disc morphology does not automatically establish traumatic causation, and a single MRI often cannot reliably date when a disc finding developed.
When causation is a clinical question, the imaging needs to be considered alongside the event history, symptom onset, prior symptoms, prior imaging when available, examination findings, competing explanations, and the patient’s course over time.
A new MRI finding after an accident may be clinically important, but the fact that it is visible after the event does not by itself prove when or why it developed.
Auto Accident & Injury Care →Timing and causation require context.
The MRI is part of that analysis, not the entire analysis.
WHAT HAPPENS AFTER THE MRI?
Once the MRI is available, the next step depends on what the imaging shows and how well those findings fit the clinical picture.
That may support continued conservative care, a change in rehabilitation, additional evaluation, referral or co-management, a procedure consultation, surgical consultation, or simply reassurance that a concerning finding is not present.
An abnormal MRI does not automatically mean surgery. The treatment pathway depends on the patient’s symptoms, neurologic findings, function, imaging, and response over time.
BRINGING YOUR MRI TO STRATEGIC
If you already have an MRI, bring the radiology report if you have it. If possible, also bring access to the actual images or let us know where the study was performed.
Reviewing the report together with the clinical history and examination can help clarify which findings appear relevant, which may be incidental, and what questions still need to be answered.
Have an MRI report you do not understand?
Bring it with you. We can walk through the terminology in the context of your symptoms and examination.
PROMPT MEDICAL ATTENTION
Prompt medical evaluation may be appropriate when symptoms include significant or progressive weakness, major changes in walking or balance, new bowel or bladder dysfunction, numbness in the saddle region, or other rapidly worsening neurologic symptoms.
If symptoms appear urgent or potentially life-threatening, seek appropriate emergency medical care rather than waiting for a routine appointment to review imaging.
