Positron Emission Tomography After Ischemic Brain Injury: Current Challenges and Future Developments.

abstract：:Pathophysiological findings of early brain injury in humans have not permitted conclusive determinations. We explored the essence of this phenomenon by taking intraoperative cortical specimens of Hunt-Kosnik grades IV~V (poor-grade) subarachnoid hemorrhages (SAH). From 2013 to 2017, we treated 39 consecutive poor-grad...
