Using quantitative PET, the authors studied the binding of [C-11]PK11195, a marker of activated microglia, in the thalamus of patients with chronic middle cerebral artery infarcts. All patients showed increased [C-11]PK11195 binding in the ipsilateral thalamus, indicating the activation of microglia in degenerating projection areas remote from the primary lesion. A persistent increase in [C-11]PK11195 binding suggests active, long-term thalamic microstructural changes after corticothalamic connection damage.
