Why MRI reports sound scarier than they are
Radiologists write reports in precise medical terminology meant for other doctors, describing every visible finding — including completely normal age-related changes that don't need any treatment. When patients read these reports directly, ordinary findings can sound like serious problems. Here are the ten terms I'm asked to explain most often.
1. Disc desiccation
What it sounds like: Something drying up and failing.
What it actually means: The disc has lost some water content — a completely normal part of aging, similar to how skin loses elasticity over time. Visible on MRI from your 20s onward in many people, often with zero symptoms.
2. Disc bulge
What it sounds like: A disc about to burst.
What it actually means: The disc extends slightly beyond its normal boundary, but the outer ring remains intact. Extremely common, often found incidentally, and frequently doesn't cause any symptoms at all.
3. Annular tear / fissure
What it sounds like: The disc is torn apart.
What it actually means: A small crack in the outer ring of the disc — not a structural failure of the whole disc. Can sometimes be a genuine pain source, but is manageable with conservative treatment in most cases.
4. Facet arthropathy / facet joint hypertrophy
What it sounds like: Joint disease.
What it actually means: Wear-and-tear changes in the small joints at the back of your spine — essentially the spine's version of arthritis, similar to what many people develop in knees or hips with age.
5. Spondylosis
What it sounds like: A specific disease.
What it actually means: Simply the medical term for general age-related wear and tear of the spine — bone spurs, disc changes, joint changes. Most adults over 40 show some degree of spondylosis on MRI.
6. Neural foraminal narrowing
What it sounds like: A nerve being crushed.
What it actually means: The opening where a nerve exits the spine has narrowed somewhat — this ranges from mild (often no symptoms) to severe (can cause nerve symptoms). The severity grading matters far more than the presence of narrowing itself.
7. Schmorl's nodes
What it sounds like: An ominous growth.
What it actually means: Small indentations where disc material has pushed into the vertebra above or below — almost always an incidental finding with no symptoms, found in roughly half of adults.
8. Degenerative disc disease
What it sounds like: A progressive, serious disease.
What it actually means: Despite the word "disease," this just describes normal age-related disc changes. It's a description, not a diagnosis requiring active treatment in most cases.
9. Mild canal stenosis
What it sounds like: Dangerous narrowing of your spinal canal.
What it actually means: Some narrowing of the spinal canal — the word "mild" is doing important work here. Mild stenosis frequently causes no symptoms and rarely needs surgery; it's the moderate-to-severe grades, especially with symptoms, that warrant closer attention.
10. Modic changes (Type 1 or 2)
What it sounds like: Unclear, technical, alarming by association.
What it actually means: Changes in the bone next to a disc — Type 1 indicates more active inflammation (sometimes more painful), Type 2 indicates more stable, chronic change. Useful information for your doctor, not inherently a marker of severe disease.
✅ The key principle
An MRI describes anatomy — it doesn't, by itself, diagnose pain. Many of these findings appear in people with zero back pain at all. What actually matters is whether your specific symptoms correlate with the specific findings, which is exactly what a proper clinical assessment determines.
When MRI language genuinely does warrant more attention
Not everything on an MRI is benign — terms like "cord compression," "myelopathy," "fracture," or "mass/lesion" do warrant prompt clinical attention. The point isn't that all MRI findings are harmless, but that many of the routinely alarming-sounding ones genuinely are.

The bottom line
MRI reports are written in a technical dialect designed for doctors, not patients — and that gap causes unnecessary anxiety. Most of the alarming-sounding terms above describe common, often harmless findings. If your report leaves you worried, the right next step isn't to assume the worst — it's to get a clear explanation of what your specific findings mean for your specific symptoms.
