Hemodynamic quantification for modelling functional outcome in stroke population using 4D Flow Imaging – a pilot study

Motivation: Recurrent stroke is associated to hemodynamic abnormalities in ischemic stroke population, and MRI may play a major role in routine clinical setting. Goal(s): Our goal was to assess hemodynamic variation in aortic region in stroke population (especially in subacute phase) undergoing routine treatment. Approach: we used 4D flow imaging method which employs a non-contrast method with respiratory motion compensation method to acquire flow dynamics in stroke population to assess the aortic flow quantification. Results: Flow abnormalities are significantly differing across subacute phase suggesting changes in hemodynamic. Impact: Understanding cardiac flow dynamics in subacute phase of stroke population (undergoing clinical treatment) can help in understanding the functional recovery pattern to stratify recovery from recurrent stroke condition in future.
