Poststroke Collaterals on MRI feat. Cynthia Greene

In this AJNR Author Interview, Dr. Francis Deng speaks with Dr. Cynthia Greene about her article, "Posttreatment Follow-Up MR Imaging Biomarkers of Collateral Status Are Associated with Short-Term Outcomes in Large-Vessel Acute Ischemic Stroke." In a retrospective study of follow-up MRI after anterior-circulation large-vessel occlusion stroke, a greater burden of FLAIR hyperintense vessels was associated with worse short-term neurologic outcomes, even among successfully reperfused patients, suggesting persistent FLAIR hyperintense vessels may mark ongoing perfusion abnormality or possible no-reflow physiology.
