Brain MRI

Understand your brain MRI — in language that actually makes sense

Upload your brain (head) MRI and get a clear, plain-language explanation of what the findings mean — the white matter "spots" everyone worries about, small vessel changes, cysts, and the incidental findings that are usually nothing.

Why brain MRI reports cause so much anxiety

Few reports are as frightening to read as a brain MRI. Words like "lesion," "white matter hyperintensity," and "signal abnormality" sound alarming — but they're routine descriptive terms, and most of what they describe is common and non-urgent.

A large share of brain MRIs turn up small white matter "spots," tiny cysts, or sinus changes that are incidental — present by chance, unrelated to why you had the scan, and seen in many healthy people, especially with age or high blood pressure. Finding something is not the same as finding something dangerous.

ReadYourLab reads your images with Google's medical AI and rewrites the report in plain language: what each finding is, how common it is, and which findings genuinely warrant a prompt conversation with your doctor. It's an informed first look to reduce the guesswork before your appointment — not a diagnosis.

Common brain MRI findings — explained

The terms that show up most often on head MRI reports, and what they usually mean.

White matter hyperintensities ("spots")

Very common

Bright dots or patches in the brain's white matter on T2/FLAIR images. Extremely common, especially past middle age or with high blood pressure, and usually reflect small vessel wear rather than anything acute. Their meaning depends on how many, where, and your age.

Full explanation

Small vessel / microvascular disease

Common with age

A catch-all term for the changes that build up as the brain's tiniest blood vessels age. Very common, strongly linked to blood pressure and vascular health, and usually managed by looking after those risk factors rather than by treating the scan.

Full explanation

Lacunar infarct

Old vs new matters

A small area of past damage from a tiny blocked vessel. Many are old and silent, discovered by chance. Whether it matters depends on whether it's new and on your vascular risk factors — worth discussing with your doctor.

Full explanation

Arachnoid cyst

Usually harmless

A fluid-filled sac between the brain and its covering membranes. Almost always present from birth, usually causes no symptoms, and is typically an incidental finding that just needs noting.

Full explanation

Sinus & mastoid changes

Incidental

Brain MRIs capture the sinuses and mastoid air cells at the edges of the image. Mucosal thickening or fluid there is common, often reflects allergies or a recent cold, and is usually unrelated to the reason for the scan.

Full explanation

Demyelinating lesions

Ask your doctor

Lesions in a pattern that can be associated with conditions like multiple sclerosis. This is a finding to review promptly with a neurologist — pattern, location, and your symptoms all matter, and imaging alone does not make the diagnosis.

Full explanation

Pituitary microadenoma

Context matters

A small, usually benign growth of the pituitary gland. Often incidental and harmless, but sometimes followed up with hormone tests depending on size and your symptoms.

Full explanation

Aneurysm

Discuss promptly

A bulge in a brain artery wall. Small, unruptured aneurysms are sometimes found incidentally and are often simply monitored — but any mention of an aneurysm should be reviewed promptly with your doctor to decide on follow-up.

Full explanation

Descriptions here are general education, not a reading of your specific scan. Some brain findings do need prompt attention — always review your report with your doctor, and seek emergency care for sudden severe headache, weakness, difficulty speaking, or vision loss.

The grading scale in your brain report

For the white matter changes that worry people most, radiologists often use one simple scale to say how extensive they are.

Fazekas scale (0–3)

Learn more

Rates how much white matter change is present, from none (0) to extensive (3). A low grade is very common and usually reflects normal aging or blood-pressure-related wear rather than a specific disease. The grade describes extent, not a diagnosis.

What your AI brain report looks like

A short excerpt from a real, anonymized brain MRI analysis — rendered the way you'll see it.

Patient explanation

Brain MRI — Plain-Language Summary

Your scan shows a few small white matter spots typical for your age, with no sign of anything acute.

There are scattered white matter changes in keeping with mild small vessel wear, graded low on the Fazekas scale. A small arachnoid cyst is present and is an incidental, benign finding. No mass, bleeding, or acute stroke is seen on this study.

Key points

  • A few small white matter spots — common, age-related small vessel change (low Fazekas grade).
  • Small arachnoid cyst — an incidental, benign finding that typically just needs noting.
  • No mass, no bleeding, and no sign of acute stroke on this series.

How to analyze your brain MRI

From files on a disc to a plain-language report in a few minutes.

  1. 1 Select the folder with your brain MRI DICOM files (.dcm) — from a CD, USB stick, or your patient portal download.
  2. 2 Preview the slices in the free online viewer to confirm you've picked the right series (T2/FLAIR are most informative).
  3. 3 Upload the series for AI analysis (a quick sign-up is needed for your first report).
  4. 4 Read your plain-language brain report in minutes, then ask follow-up questions about any finding.

Why ReadYourLab for your brain MRI

Built for patients, reviewed by a physician, honest about its limits.

Reads the whole 3D volume

The AI analyzes your full stack of slices as a 3D volume across sequences, understanding how findings relate — not one flat image at a time.

Physician-reviewed & transparent

Our approach is medically reviewed, we tell you which model read your scan, and we're clear that this is an educational first look, not a diagnosis.

Private by design

Your images are encrypted in transit and at rest, never sold, and you can delete them at any time. GDPR compliant.

Brain MRI analysis — frequently asked questions

Common questions about AI brain MRI analysis, white matter spots, and what your report means.

Can AI read my brain MRI?

Yes. Upload your brain (head) MRI DICOM files and the AI produces a plain-language explanation of the findings — white matter changes, small vessel disease, cysts, and incidental findings — in a few minutes. It's an educational first look to help you understand your report and prepare questions, not a diagnosis or a replacement for your radiologist or neurologist.

What does the Fazekas scale mean?

The Fazekas scale is a simple 0-to-3 rating of how extensive white matter changes are, from none to extensive. A low grade is very common and usually reflects normal aging or blood-pressure-related wear rather than a specific disease. It describes extent, not a diagnosis.

Is my brain MRI kept private?

Yes. Your images are encrypted in transit and at rest, are never shared with third parties or sold, and you can delete them at any time. ReadYourLab is GDPR compliant.

Is this a diagnosis or a replacement for my doctor?

No. ReadYourLab is an educational tool, not a medical device, and does not provide a diagnosis. The AI can be wrong — it may miss real findings or describe ones that aren't clinically important. Always review your results with your own doctor, and seek emergency care for sudden severe headache, weakness or numbness on one side, trouble speaking, or sudden vision changes.
