1 Hyperperfused stroke territory on ASL
Hyperperfused stroke territory on ASL. A 73-year-old woman with atrial fibrillation and embolic infarcts in the left posterior cerebral artery and posterior watershed territories. Hyperperfused stroke territory on ASL. A 73-year-old woman with atrial fibrillation and embolic infarcts in the left posterior cerebral artery and posterior watershed territories. Punctate areas of restricted diffusion are seen (left, yellow arrow). ASL map (right) shows gyral hyperperfusion in the left hemisphere (white arrow). Hypoperfusion is also seen in the right posterior watershed territory. A.R. Deibler et al. AJNR Am J Neuroradiol 2008;29: ©2008 by American Society of Neuroradiology
