A scan does not find your pain.
It finds FINDINGS and photographs it.
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.
A report is a description of what the machine saw. Whether it explains what you feel is a separate judgement, and it belongs to a clinician who has examined your hand.
What each scan is actually good at
- 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, occult fractures. Best soft-tissue detail, most expensive, most likely to find things that don’t matter
- CT. Bone in three dimensions. The tool for confirming whether a scaphoid has united, and for planning complex fracture surgery
The words 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 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 increasingly common with age
- Cannot exclude. Radiologist language for “I am not ruling this out on this image.” It is not a diagnosis
- 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.
How a good clinician reads it
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.
When a scan genuinely changes things
- Suspected fracture not visible on X-ray, especially the scaphoid
- Suspected ligament instability after a fall with a normal X-ray
- A lump that needs characterizing before anyone operates
- Planning surgery, where the surgeon needs the anatomy in advance
- Symptoms that have not behaved as expected after a reasonable trial of treatment
If the result would not change the plan, the scan is costing you money and worry rather than information.
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
- Resist the urge to search each phrase individually. Every term in a radiology report has a worst-case version, and the internet will find it for you
The scan describes the hand. Only an examination explains it.
