WASHINGTON, D.C.: Scientists have found a way to examine people’s brains to see if they have had small silent strokes, which are linked to a higher risk of dementia.
Previously, doctors could detect these small strokes only after death as they had to examine brain tissue under a microscope.
The new method involves using a 3-tesla (3T) magnetic resonance imaging (MRI) machine.
The 3T machines generate a stronger magnetic field than the more common 1.5T machines used in hospitals, so they yield greater detail in the scans.
