Nordic Chapters Tech-Talk Series; Event 1: Acute Ischemic Stroke Analysis: Integrating Clinical Advancements and AI Solutions
Tech-talk with title: Acute Ischemic Stroke Analysis: Integrating Clinical Advancements and AI Solutions
By: Associate Prof. Mahdieh Khanmohammadi
Abstract:
Stroke remains a critical neurological emergency with significant societal and health impacts worldwide. In Norway, 15,000 people suffer from acute cerebral stroke annually, the leading cause of adult long-term severe disability, nursing home admissions, and the third leading cause of death. Rapid and accurate identification of ischemic regions in the brain is crucial for timely intervention and treatment planning in acute ischemic stroke patients. At Stavanger University Hospital, Computed Tomography Perfusion (CTP) scans and derived parametric maps are used to determine the need for immediate treatment with intravenous thrombolysis (IVT) alone or in combination with mechanical thrombectomy (MT), or MT alone. During follow-ups, patients undergo Diffusion Weighted Imaging (DWI) to evaluate the treatment outcomes.
This talk highlights a twin project combining clinical and technical research to enhance the diagnosis and treatment of acute ischemic stroke. The clinical PhD focused on optimizing stroke management through advanced imaging protocols and simulation-based team training, achieving significant reductions in treatment delays. The technical PhD explored artificial intelligence methods to automatically segment ischemic regions from CTP scans, emphasizing both irreversibly damaged core and salvageable penumbra. By leveraging supervised and semi-supervised machine learning approaches, the research demonstrated the feasibility of 4D CTP as a robust input for segmentation tasks. Now we are moving towards evaluating combinations of features in ischemic lesions at hospital admission CTP and follow-up DWI to predict outcomes and guide treatment, analyzing the effect of interventional treatments. Finally, we aim to implement the developed system in a clinical workflow for simulation training and research.
