We included only patients in whom computed tomography (CT) confirmed the presence of single lacunar infarct in the unilateral putamen (right 3 cases, left 5 cases) or posterior limb of the internal capsule ( right 4 cases, left 3 cases ). Regional cerebral blood flow (rCBF) was measured using the two dimensional 133Xe inhalation technique during subacute or chronic phase of stroke. Fifteen patients were aged 45-74 years old, and they suffered from vertigo, headache, or mild hemiparesis.
