Course
MRI perfusion (ASL) in stroke — penumbra clues, mismatch concepts, and limitations (Advanced)
Advanced course: arterial spin labeling (ASL) MRI perfusion can estimate blood flow without contrast in some settings. Learn how clinicians use perfusion–diffusion mismatch concepts, what ASL can/can’t show, and when CT perfusion is used instead
