Keywords: Stroke, fMRI (resting state)Through the use of resting state functional MRI, diffusion tensor imaging (DTI), and a unique canine stroke model, our study explored the functional and structural effects of maintaining perfusion pressure as a means of extending the window of opportunity for thrombectomy. In our preliminary results, the employment of flow augmentation indicated a maintenance of functional connectivity, mean T2* signal intensity, and mean diffusivity in the ischemic region. Through this we have shown a potential method of extending the "door-to-needle time" in stroke treatment and possible therapeutic effects of flow augmentation therapy in acute stroke.
