Abstract

Stroke is one of the leading causes of death and disability worldwide. Standard treatment for stroke is intravenous (IV) injection of tissue plasminogen activator (t-PA) rapidly after symptom onset. However, there are limitations of IV t-PA treatment, such as a short time window for administration and risk for hemorrhage. Recent trials have demonstrated the benefit of endovascular treatment when added to standard treatment to improve outcomes for patients. Advanced imaging was utilized in some trials to identify patients with proximal intracranial occlusion to target for endovascular reperfusion therapy, and to exclude patients with large infarct cores or poor collateral circulation who would not be expected to benefit from intervention. This article summarizes the use of imaging in recent stroke trials in details, provides a stroke imaging protocol, and provides tips which radiologists should know to help their neurointerventionalists.
