Background: Reperfusion therapies are highly time-sensitive, necessitating streamlined protocols to ensure that each step meets target times. This is especially critical for wake-up strokes where emergent brain magnetic resonance imaging (eMRI-brain) included in the evaluation process. Stroke alerts, particularly patients with aphasia or altered mental status, present additional challenges confirming absence of metal foreign bodies, leading time-consuming imaging. Implementing integrate a full-body-scout (FBS) during non-contrast computed tomography head (CT head) could reduce delays and enhance safety efficiency eMRI clearance, thereby improving likelihood timely thrombolysis. Objective: To standardize stroke alert process eMRI-brain on cases door-to-eMRI times eligible by implementing FBS CT (FBS-CT) protocol. Methods: We reviewed metrics before after FBS-CT protocol between August 01, 2022 July 31, 2024. The consisted adding assess whether patient had any bodies avoid need Results: identified thrombolysis from 2,300 alerts at an academic comprehensive center. classified into two groups: Pre-FBS-CT group (n=53; mean age 58.05± 15.34 ; 66% female; 58% White) Post-FBS-CT (n=72; 60.44 ±13.70, female, 72% white). Door-to-eMRI median time was 79 [IQR 50-116] 45 36.75 -57] min group. Thrombolytic given only 1 while 12 received it. Conclusions: significantly decreased reduced variability those Although we cannot definitively attribute increased eligibility administration solely improved group, our data demonstrates substantial reduction following implementation. It important note onset may have influenced presence DWI-FLAIR mismatch. Nonetheless, crucial impact reperfusion therapies.
