What are Punctuate subcortal T2 hyperintensity foci?

Punctate subcortical T2 hyperintensity foci refer to small, bright spots observed on T2-weighted MRI scans of the brain, typically located in the subcortical white matter. These hyperintensities can indicate various conditions, including small vessel disease, demyelination, or other forms of brain pathology. They are often associated with age-related changes and may correlate with cognitive decline or vascular risk factors. Clinical significance depends on the context and associated symptoms.
