According to the 'time-is-brain' concept in acute stroke, recanalization of the obstructed blood vessels has to be performed within the very first hours after symptom onset. However, patients mostly come too late to the hospital and, therefore, only a minority of patients (5-10%) obtains the time-sensitive recanalizing treatments, and if so, mostly too late.[1] As a potential solution to the problem of detrimental delays in stroke management the Mobile Stroke Unit concept was developed enabling diagnosis and treatment directly at the emergency site as opposed to awaiting the patient's arrival at hospital for treatment. Apart from the earlier start of treatment, knowledge about the type of stroke already in the pre-hospital phase of stroke management allows accurate triage decisions in regard to the most appropriate target hospital, e.g., hospital with or without endovascular or neurosurgical treatment options.
