Why the radiologist wrote it that way
At each level of the spine, a nerve root exits through a small opening on each side called the neural foramen. Disc bulges, bony spurs (osteophytes) and thickened facet joints can all crowd that opening. Radiologists grade the narrowing at each level and side, often with the cause — for example "mild right neural foraminal narrowing due to a disc bulge and facet arthropathy". The term "foraminal stenosis" means the same.
Is this good or bad news?
Mild foraminal narrowing is very common on spine MRI in adults and often causes no symptoms. Narrowing becomes more relevant as it becomes more severe, especially if the report says the exiting nerve root is contacted or compressed. Symptoms from a squeezed nerve typically follow that nerve’s path — down an arm from the neck, or down a leg from the lower back — and doctors check whether the side and level on the scan match where you feel things. A mismatch usually means the narrowing is not the explanation.
What it does not mean
- That a nerve is trapped. Narrowing describes space; the report says separately if the nerve is affected.
- That every narrowed level is causing pain. Many people have several levels described.
- That it needs surgery. Mild and moderate narrowing is usually managed without it.

One phrase is not the whole report
What this sentence means for you depends on everything else your report says. Radily reads the whole thing and explains it in plain English — and can talk you through it on video, so you are not reading medical language alone.
Other phrases on your report
- Cannot be excludedThe images are not able to completely rule this out — which is a statement about the limits of the scan, not a suggestion that it is likely.
- NonspecificThe finding is real, but its appearance is not distinctive enough to say what is causing it.
- Small pleural effusionA small amount of fluid has collected in the space between the lung and the chest wall.
- Hepatic steatosisFat has built up in the liver — commonly called fatty liver.
This explains how a phrase is commonly used in radiology reports. It is not a diagnosis, not a reading of your scan, and not medical advice. Only your doctor can tell you what your own report means.
