Abstract
Brain and cerebrovascular imaging play a critical role in acute ischemic stroke treatment. The choice of imaging modalities and techniques depends on several factors, such as severity of symptoms and time from symptom onset, as well as the interventions being considered, namely, intravenous thrombolysis and endovascular thrombectomy (ET). While computed tomography (CT) is the main imaging used for patient triage, magnetic resonance imaging (MRI) may be used in specific scenarios such as stroke mimics. It is very important to streamline a stroke imaging protocol in every hospital to expedite treatment decisions and standardize treatment algorithms. CT perfusion (CTP) may be used to triage patients for ET after 6 hours from symptom onset. In this chapter we discuss CT and CTP as the main imaging modalities for stroke triage, and we share our acute ischemic stroke imaging protocol.
