NCT03670862

Brief Summary

Prediction model for the Recanalization OuTcome Evaluation of ischemic stroke using multimodal CT (PROTECT) study was a multicenter prospective observational study that recruited patients from 13 centers located in 10 provinces across China. The study was to assess the effects of novel imaging biomarkers/ imaging patterns based on multimodel CT for patients selection and outcome prediction in acute ischemic stroke.
