ABSTRACT

Stroke Imaging Abstract. In recent decades, imaging has become indispensable for the diagnosis and therapy of stroke. It provides information necessary to distinguish between hemorrhagic and ischemic stroke, to identify the cause of the symptoms and to determine the time of stroke. Increasingly, imaging is being used as a tool for making optimal therapeutic decisions. In particular, the advent and success of mechanical thrombectomy has significantly changed the management of patients with ischemic stroke. Computed tomography (CT) and magnetic resonance imaging (MRI) allow for identifying patients who may benefit from revascularizing therapy, even outside the previously valid, dogmatic time windows. Advances in imaging modalities both in CT and MRI, allow for identifying salvageable brain tissue, independent from the time factor, advocating individualized decision making for optimal therapy and prognosis. The choice of the appropriate imaging modality depends on several criteria, such as suspected and differential diagnosis, urgency, patient age and availability of the scanner.
