Investigating the relationship between venous perfusion timing and volumetric parameters

Takeaway

  • A change in venous drainage pattern underlies ventricular enlargement in normal ageing and traumatic brain injury (TBI).

Why this matters

    Blood oxygenation level-dependent (BOLD)-based lag-mapping is a non-invasive, repeatable method, which can be used to detect venous insufficiency and offer potential benefits in preventing secondary hydrocephalus.
