Development and external validation of a stability machine learning model to identify wake-up stroke onset time from MRI

ConclusionsThe svmRadial model using DWI  + FLAIR is the most stable and generalizable for identifying the onset time of wake-up stroke patients within 4.5 h of symptom onset.Key Points• Machining learning model helps clinicians to identify wake-up stroke patients within 4.5 h of symptom onset.• A prospective study showed that svmRadial model based on DWI + FLAIR was the most stable in predicting the stroke onset time.• External validation showed that svmRadial model has good generalization ability in predicting the stroke onset time.
