Valuation of cerebral perfusion examination in assessment of ischemic cerebrovascular disease / 中华神经科杂志

ABSTRACT

Cerebral perfusion indicates the hemodynamics in the microcirculation of brain tissue. Although there are many methods of cerebral perfusion examination, CT perfusion and magnetic resonance perfusion are most commonly used to assess the cerebral perfusion in ischemic cerebrovascular diseases. The basic parameters include cerebral blood flow, cerebral blood volume, mean transit time, and time to peak. Cerebral perfusion examination is valuable to diagnose atypical transient ischemic attack, to direct the intravenous thrombolysis and endovascular mechanical thrombectomy in acute ischemic stroke, to assess cerebral flow compensation and collateral circulation distal to chronic cerebral artery stenosis, and to screen the patients with asymptomatic cerebral artery stenosis for the therapy of revascularization.
