Idiopathic intracranial hypertension is a condition of elevated intracranial cerebrospinal fluid pressure. Transverse sinus stenoses are clearly related to the pathophysiology, and catheter-based manometry is the “gold standard” to assess pressure gradients across these stenoses. The aim of this work is to evaluate the feasibility of assessing these pressure gradients in the intracranial veins using 4DFlow with ICOSA6 motion encoding – which also account for turbulence - and to compare these pressure gradients with catheter-based manometry. Pressure gradient were measured in patient specific phantoms using both 4DFlow and catheter-based manometry. The pressure gradient assessed showed good agreement when accounting for turbulence.
