DWI/PWI mismatch is method to identify acute stroke patients that might benefit from reperfusion therapies. We have implemented a fully automated system aimed on assessment of mismatch from DWI and Tmax perfusion maps. The automated approach can deliver the mismatch maps within 5 minutes after the scan to scanner and PACS. The statistical evaluation of 74 cases has shown robustness of the system and good correlanion between manual and automated results.
