The Role of the Signal Intensity Ratio on Fluid-Attenuated Inversion Recovery in Stroke Patients Achieving Successful Recanalization with Endovascular Treatment

Contrary to our hypothesis, FLAIR hyperintensity on initial MRI before EVT was not associated with lesion growth in patients who were recanalized successfully with EVT. Instead, our results suggest that time interval from MRI acquisition to recanalization is an independent predictor of lesion growth.
