Noncontrast versus perfusion CT to select endovascular therapy in an extended time window: Systematic review/meta-analysis.
The effect of noncontrast CT (NCCT) on the eligibility for endovascular therapy (EVT) in an extended time window remains to be elucidated. We sought to assess the efficacy and safety of NCCT in comparison with CT perfusion (CTP) in selecting patients with acute ischemic stroke (AIS) for EVT 6-24 hours after onset. ⋯ These findings suggest that NCCT is as effective as CTP in selecting patients for EVT in an extended time window.
