The maximum time allowed for ordering brain imaging after a patient's arrival for suspected stroke is 10 minutes. This time frame is crucial because early diagnosis and treatment of strokes can significantly affect patient outcomes. Prompt imaging, such as a CT scan or MRI, is essential to quickly differentiate between ischemic and hemorrhagic strokes, allowing for the appropriate intervention to be initiated without delay.

Delaying imaging can result in the loss of valuable time, which is critical given the time-sensitive nature of stroke treatment protocols, including the administration of thrombolytics for ischemic strokes. The focus on a 10-minute window emphasizes the necessity of swift action in emergency settings, aligning with established stroke protocols aimed at improving survival and functional outcomes for patients. Thus, this option highlights the importance of rapid assessment in the management of suspected strokes.
