In plain language
Normal, with the acknowledgement that "normal" is a range rather than a single value. A measurement or an appearance sits inside what is expected for someone of your age and build.
Where you’ll see this
Next to anything that gets measured — an artery, a bile duct, the width of the spinal canal — on CT, MRI and ultrasound reports.
Your report may word it “WNL” or “Normal limits”. These mean the same thing.
Questions worth asking your doctor
- Does this wording mean you are unsure, or that you are reasonably confident and being careful?
- If something cannot be ruled out from this scan, what would rule it out?
- Is there anything here you would act on today?
Careful and hedged wording
