A simple MRI method that measures iron content can provide a more comprehensive picture of the consequences of stroke-related damage to the brain.Researchers said the findings point to a role for MRI brain iron measurements in monitoring recovery from stroke.
Strokes can result in significant impairments caused by infarctions, or the death of tissue due to the brain's blood supply being blocked by a clot. Long-term outcomes may also be affected by delayed degeneration of brain areas away from the location of the stroke. One such area is the substantia nigra (SN), a structure of the midbrain that is connected with other parts of the brain in several complex networks.
