Summary

This is a sample reading of a normal-appearing brain MRI, shown to demonstrate how Read Your Scan explains imaging in plain language. The brain tissue, fluid spaces, and midline structures look within normal limits for the template used, with no sign of bleeding, a mass, or a blocked fluid space.

Key findings

  • Brain tissue (grey and white matter) appears normally formed and symmetric.
  • The fluid-filled spaces (ventricles) are normal in size and centred — no build-up of pressure.
  • No evidence of bleeding, stroke, or a mass lesion on the images reviewed.
  • Midline structures are central, without shift.

What this can mean

On this sample scan there is nothing that looks urgent or abnormal. In a real reading, anything notable would be listed here in everyday language and marked on the 3D viewer so you can see exactly where it is. This explanation never replaces your doctor or radiologist — it helps you understand and ask better questions.

Questions for your doctor

  • 1.Does this scan explain my symptoms, or should anything else be looked into?
  • 2.Is any follow-up imaging needed, and if so, when?
  • 3.Are there findings here that are expected for my age?

Glossary

Ventricles
Fluid-filled spaces deep inside the brain that cushion it and carry cerebrospinal fluid.
White matter
The brain’s wiring — bundles of nerve fibres that connect different regions.
Midline shift
When pressure pushes brain structures off-centre; its absence is reassuring.

Sample content for demonstration. This is an automated, informational explanation of imaging — not a medical diagnosis. Always rely on your doctor and radiologist.

Findings

01/03

Swipe or use ‹ › to move between findings. “View on scan” opens the viewer and jumps the crosshair to that region.

Lateral ventricles

high confidence

Normal size and symmetric — no enlargement to suggest raised pressure. (Sample marker.)

Right periventricular white matter

moderate confidence

No focal signal change on this sample. In a real study, small spots would be flagged and shown here.

Brainstem / midline

high confidence

Central and normally formed — no midline shift. (Sample marker.)
