Overview

Retrospective cohort study explored ASL perfusion patterns and clinical outcomes in anoxic brain injury, suggesting potential associations.

Key Points

  • Increased ASL signal in the left occipital lobe correlates with myoclonus status epilepticus after cardiac arrest.
  • Association trends were observed between right frontal ASL signal and absent motor reflexes at day 3 post-arrest.
  • ASL scores of 7 or higher were linked to higher odds of absent brainstem reflexes following cardiac arrest.
  • Findings indicate limited predictive performance of ASL imaging, warranting larger, prospective studies to assess its prognostic value.
