Course

Deep watershed infarcts — internal border zones, hypoperfusion clues, and MRI patterns (Advanced)

Advanced course: deep/internal watershed infarcts occur in border zones between deep perforator and cortical supplies, often linked to low flow or severe stenosis. Learn symptom patterns, MRI distribution clues, and vessel imaging workup
