A patient often arrives at my clinic already holding an MRI report, sometimes obtained before we've even had a conversation about their symptoms. There's a quiet assumption behind this: that a scan is the most reliable way to find out what's wrong, and that whatever it shows must be the cause of the pain.
It's an understandable assumption — and it's usually wrong.
What an MRI actually does
An MRI is extraordinarily good at certain things. It can identify infection, tumours, fractures, and significant nerve compression with remarkable clarity. It's also essential once we've already decided surgery is the right path, because it gives us a precise map before we operate.
What it is not good at is telling us why an otherwise healthy spine is sore.
The uncomfortable statistic
Multiple studies have scanned the spines of people who have no back pain at all and found disc bulges, disc degeneration, and even herniations in a large proportion of them. Conversely, plenty of people with significant pain have scans that look almost unremarkable. Put simply, the correlation between what an MRI shows and what a patient actually feels is far weaker than most people expect — a large share of "abnormal" findings have no real bearing on the symptoms a patient walks in with.
Why this matters for you
This isn't a reason to distrust imaging — it's a reason to use it at the right time, for the right question. Ordered too early, before a proper history and examination, an MRI can do more harm than good. A report full of unfamiliar terms — bulge, degeneration, desiccation, annular tear — can frighten a patient into believing their spine is falling apart, when in fact many of these are simply age-related findings, similar to grey hair or skin wrinkles, and not the source of their pain at all.
In my practice, the clinical picture — what aggravates your pain, what relieves it, what your examination shows — usually tells me more than the scan does, especially in the first several weeks. Imaging earns its place later, if symptoms persist or if there are specific red-flag signs that warrant a closer look.
The takeaway
A scan is a tool, not a verdict. Don't let a report full of intimidating language define how serious your back pain is — let your doctor put those findings in context with what you're actually experiencing.
