Hypoxic-ischemic brain injury vs focal stroke — diffuse MRI patterns and clinical clues (Advanced)

Advanced course: not all ischemic brain injury is a focal ‘artery territory’ stroke. After cardiac arrest or severe low oxygen, MRI may show diffuse patterns. Learn how clinicians distinguish diffuse hypoxic injury from focal infarct/hemorrhage

What you'll learn

  • Understand the difference between focal arterial stroke and global hypoxic-ischemic injury
