Stroke, which is an insufficient blood supply to the brain,  is the 4th cause of death and disability world-wide. Recently, it has been demonstrated in large studies that direct extraction of the thrombus (using stent retrievers) is an effective treatment for patients with ischemic stroke. Timing is crucial in these interventions: the sooner a thrombus is removed, the more brain tissue may be rescued. Despite the latest advancement in imaging technology and development of instruments such as stent-retrievers, not all patients do benefit from treatment. Treatment of ischemic stroke is not without risks, and prediction of treatment success remains difficult. Therefore, a careful selection of patients for particular treatment strategy may be important for the outcome of the patients.  In clinical practice, patients generally undergo non-contrast CT imaging, as well as a contrast-enhanced protocol (single phase CTA, multiphase CTA, or CT Perfusion). Much information can be obtained from the clinical images, such as the composition of the thrombus, the collateral flow and perfusion of brain tissue, but few validated tools and quantitative imaging biomarkers have been developed and evaluated for clinical use so far. Therefore, it is the purpose of this Special Session to draw attention to the need, the relevance and the opportunities of developing imaging biomarkers for ischemic stroke treatment. To that end, we composed a program with presentations by experts in stroke imaging, with a clinical background as well as with a technological background.
