Key Points

To determine whether cerebral magnetic resonance perfusion imaging features can distinguish acute symptomatic from chronic asymptomatic internal carotid artery occlusion.
Retrospectively analyzed patients with unilateral internal carotid artery occlusion who underwent magnetic resonance perfusion across multi-institutional cohorts.
Categorized cases into chronic asymptomatic (no stroke or transient ischemic attack for at least 1 year) and acute symptomatic (stroke symptoms within 24 hours of imaging), excluding patients with significant contralateral stenosis.
Computed perfusion parameters—including time-to-maximum, mean transit time, cerebral blood flow, and cerebral blood volume—using automated RAPID software.
Perfusion profiles demonstrated distinct hemodynamic patterns capable of differentiating acute symptomatic occlusions from chronic asymptomatic presentations.
Automated perfusion mapping captured variations in tissue transit delay and compensatory collateral blood flow between acute and chronic occlusion states.
