Indicated for: Everyone

If hemorrhage identified, see Acute Bleed

If early ischemic change, continue acute stroke algorithm, see ASPECTS scoring

If late ischemic change, unlikely to be intervention candidate

Indicated for: Everyone (unless there is virtually no suspicion of acute stroke potentially amenable to intervention)

If large vessel occlusion (LVO = ICA, M1, M2, Basilar) identified: activate NeuroIR +/- obtain further imaging (see Acute Intervention Algorithm)

Indicated for:

• potential thrombectomy candidate with last known well 6-24 hours ago

• potential tPA candidate with last known well 4.5-9 hours ago, per EXTEND criteria

See Acute Intervention Algorithm for inclusion/exclusion criteria based on CT Perfusion results
