Tiny brain strokes often invisible on later scans, study finds

This study looked at 59 patients who had very small strokes (called microinfarctions) in either the cerebrum or cerebellum. Researchers wanted to see how often these tiny spots could still be seen on follow-up MRI scans done in routine care. The goal was to understand if MRI is better at detecting old microinfarctions in the cerebellum compared to the cerebrum.
