21

Results

In these patients, the volumes with increased OEF values of>51.5%, which was defined using the anterior circulation territory OEF values from the 21 healthy controls, were positively correlated with the ischemic penumbra volumes and inversely correlated with the 30-day change in the National Institutes of Health Stroke Scale scores.

Baseline Characteristics

This prospective imaging study included 21 patients with
large anterior circulation vessel occlusion who were admitted <24 h after stroke onset
and 21 age-matched healthy controls.

Participant flow

We identified the ischemic penumbra as the region
with a Tmax of>6 s during dynamic susceptibility contrast-magnetic resonance imaging
(DSC-MRI) and calculated the perfusion-core mismatch ratio between the ischemic
penumbra and infarct core volumes. The OEF values were measured based on magnetic
susceptibility differences between the venous structures and brain tissues using rapid
QSM acquisition. Volumes with increased OEF values were compared to the ischemic
penumbra volumes using an anatomical template.

Adverse events

None

Outcome measures

In these patients, the volumes with increased OEF values of>51.5%, which was defined using the anterior circulation territory OEF values from the 21 healthy controls, were positively correlated with the ischemic penumbra volumes and inversely correlated with the 30-day change in the National Institutes of Health Stroke Scale scores.
