Prognosis in Subacute Ischemic Stroke Using Multimodal Imaging

The First Hospital of Hebei Medical University28 enrolled

Overview

We enrolled patients with subacute IS, associated with moderate-to-severe stenosis of the unilateral cervical internal carotid artery, who underwent 4D ASL. Perfusion levels and collateral circulation were compared between groups with favorable prognosis (modified Rankin scale \[mRS\] ≤ 2) and poor prognosis (mRS \> 2).

Outcomes

Primary Outcomes

Modified Rankin Scale（mRS） score after 3 months of onset

mRS scores range from 0 to 6, where 0 indicates no symptoms, 3 indicates moderate disability, 4 indicates moderately severe disability, 5 indicates severe disability, and 6 indicates death. Patients were categorized into a good prognosis group (mRS ≤ 2) and a poor prognosis group (mRS \> 2).

Time frame: 3 months
