Abstract

The past year has seen rapid advances in acute stroke therapy based on advanced imaging selection [1–5]. The main aim of imaging in acute ischemic stroke (AIS) is to rule out hemorrhage and stroke mimics, to define the extension of established infarct (core), and to identify the occlusion site, which are the main factors involved in the acute treatment decision: conservative, IV thrombolysis, and mechanical thrombectomy [1–5]. Additional relevant information includes the extension of the core (or penumbra), the type and length of the clot, and the individual collateral circulation that may allow the individual AIS treatment strategies.
