A Scan Doesn’t Find Your Pain. It Finds Findings.
A hand or wrist MRI report describes what the scanner saw, not what’s causing your pain. Words like “degenerative change”, “signal change”, “tear” and “cannot exclude” are common, and often turn up in people with no symptoms at all. What matters is whether a finding sits exactly where you hurt and fits how it started. “Correlate clinically” means someone who examines you has to decide.
A scan does not find your pain.
It finds FINDINGS and photographs them.
Those are not the same thing, and the gap between them is where most of the anxiety in a radiology report lives. Plenty of people walking around with no symptoms have scans full of tears, degeneration and cysts.
So here’s the usual scene. The report lands in your inbox days before the follow-up appointment. It’s late. You read it line by line, search every phrase, and by midnight you’ve decided you need surgery.
Reading it wrong costs you either way. Treat an incidental finding as the cause, and you can end up with an operation on something that was never the problem. Dismiss the one finding that IS time-sensitive, like a hidden scaphoid fracture, and an 8 to 12 week healing problem can become a non-union.
A report is a description of what the machine saw. Whether it explains what you feel is a separate judgment, and it belongs to a clinician who has examined your hand. Here’s how to read it in the meantime.
Which scan is best for hand and wrist pain?
- X-ray. Bone. Fractures, dislocations, joint space, calcification. Cheap, fast, and blind to soft tissue. A normal X-ray does not mean a normal wrist. See the scaphoid fracture that hides.
- Ultrasound. Tendons, nerves at the wrist, fluid, ganglia. Its superpower is that it moves…the operator can watch a tendon snap or a finger trigger in real time. Very operator-dependent.
- MRI. Ligaments, cartilage, bone marrow, tumors, hidden fractures. Best soft-tissue detail, most expensive, and the most likely to find things that don’t matter.
- MR arthrogram. An MRI with dye injected into the joint first. Sometimes used to get a clearer look at small wrist ligaments and the TFCC.
- CT. Bone in three dimensions. The tool for confirming whether a scaphoid has united, and for planning complex fracture surgery.
- Nerve conduction study. Not a scan. It measures how well a nerve carries signals, so it shows nerve FUNCTION, which no picture can. Often used for carpal tunnel and cubital tunnel.
What do the words on my MRI report mean?
The ones that frighten people unnecessarily:
- Degenerative change. Wear consistent with your age. Present in most adult wrists. Not a diagnosis by itself.
- Signal change or increased signal. The MRI saw something different from the surrounding tissue. Could be swelling, could be scar, could be normal variation.
- Tear. The word that causes the most fear and carries the least information on its own. Tears of the TFCC are common in people with no pain at all, and more common with age.
- Small joint effusion. A little fluid in the joint. Often reactive or normal. It matters more when there’s also heat, redness and real swelling.
- Bone marrow edema or bone bruise. The bone itself is stressed or bruised. After a fall with pain in the snuffbox, this one gets taken seriously.
- Ganglion or small cyst. Very often incidental. It only matters if it sits where the lump or pain is. See ganglion cysts.
- Tenosynovitis or fluid in the tendon sheath. Irritated tendon lining. Relevant if your pain sits right over that tendon.
- Positive ulnar variance. The forearm bone on the little-finger side is slightly long. Many people have it without symptoms. Sometimes it goes with ulnar impaction.
- Cannot exclude. Radiologist language for “I am not ruling this out on this image.” It is not a diagnosis.
- Incidental. Seen, probably not relevant to why you were scanned.
- Correlate clinically. This is the most important phrase in the entire report. It means: I have described what I saw, now somebody who examined this patient needs to decide whether it matters.
A finding that does not match where you hurt is a finding, not a cause.
Is the finding on my scan actually causing my pain?
Three questions, in order.
- Does the finding sit where the pain sits? A tear on the little-finger side does not explain thumb-side pain, however dramatic the wording.
- Does it explain the mechanism? Did the thing you did plausibly produce this?
- Does it change what we would do? If the treatment is identical either way, the finding is interesting rather than useful.
(The most common thing I do with a scan report is talk someone down from it. The second most common is point out that the thing causing their pain was never going to appear on that scan in the first place.)
What a hand MRI can’t show you
- How the hand is being used. Grip habits, load, the 9 hours a day on a mouse. Overload problems often look boringly normal on a scan.
- How sensitive a nerve is. Early nerve compression can look normal. That’s what the examination and nerve tests are for.
- Stiffness and function. How far the joint moves, how strong the grip is, what you can’t do. Measured with a goniometer and a grip dynamometer, not a magnet.
- Whether it’s getting better. One scan is a snapshot. Your symptoms over 2 to 6 weeks are the trend, and the trend usually tells me more.
When does a scan actually change the plan?
This is where the Closing Window Method earns its keep. Most findings have no window at all. A few run on a clock:
- A hidden scaphoid fracture. X-rays can miss it in the first 10 to 14 days. An early MRI can confirm or clear it within days, so you aren’t left in a cast you don’t need, or out of one you do. See scaphoid fracture.
- A suspected ligament tear after a fall with a normal X-ray, especially the scapholunate ligament. Repair options are best in the first weeks after injury, so this one shouldn’t sit in a queue for months.
- A lump that needs characterizing before anyone operates, such as a giant cell tumor of the tendon sheath.
- Planning surgery, where the surgeon needs the anatomy in advance.
- Symptoms that haven’t behaved as expected after a fair trial of treatment, usually 6 to 12 weeks.
If the result would not change the plan, the scan is costing you money and worry rather than information.
Do I need an MRI for wrist or hand pain?
Often, no. Most hand and wrist problems are diagnosed with a history, an examination and, if needed, an X-ray. Trigger finger, De Quervain’s and most tendon overload problems don’t need an MRI at all.
An MRI makes sense when the examination points at something specific that an X-ray can’t see, AND the answer would change what happens next. If nobody can tell you what they’d do differently depending on the result, ask why you’re having it.
What to do with a report you don’t understand
- Ask for the images, not just the report. Any clinician reviewing it will want them.
- Ask directly: which of these findings explains my symptoms, and which are incidental?
- Ask what changes as a result. Treatment, timeline, whether surgery is on or off the table.
- Resist searching each phrase individually. Every term in a radiology report has a worst-case version, and the internet will find it for you. Dr. Google has never examined a hand.
- Bring a pain map. Point to exactly where it hurts. If it’s still unclear, our wrist pain by location guide helps you describe it.
Get it checked today if
- Your report mentions a fracture, or “cannot exclude fracture”, and you’re not in a cast or splint and nobody has called you.
- The report mentions infection, abscess or septic arthritis, or the joint is hot, red and swollen and you feel unwell.
- You have numbness that is constant rather than coming and going, or weakness that’s getting worse.
Get it checked if
- You’ve had the report for more than two weeks and no clinician has explained which finding matters.
- The report mentions a mass or lump and no follow-up has been arranged.
- Your pain doesn’t match anything on the report, and it’s still not improving after 6 weeks.
The scan describes the hand. Only an examination explains it.
