Can Acute Stroke Imaging Predict Outcomes Following Thrombectomy?

Size of the ischemic core, as indicated on CT or MRI, is an important variable in prognosis.

Endovascular thrombectomy (EVT) has been found to be useful for patients with ischemic stroke in two time windows: within 6 hours and from 6 to 24 hours. Penumbral imaging attempts to delineate the amount of infarcted core tissue from the amount of tissue at risk due to hypoperfusion; the difference is referred to as the area of “mismatch” or penumbra and indicates the volume that might be salvageable. Penumbral imaging plays a key role in the second time window; to investigate its role in the first window, investigators pooled data on 1764 patients (mean age, 66; 53% men) from seven trials of EVT that included baseline penumbral imaging with perfusion computed tomography [CT] or diffusion MRI. Imaging was performed within 6 hours in 99% of…
