Idiopathic intracranial hypertension. a The axial 4DFlow MRI image demonstrates a stenosis of the right transverse sinus (arrow). b The CE MRA confirms a stenosis at the junction of the transvers and sigmoid sinus (arrow). c The 4DFlow MRI velocities are elevated in the stenotic segment (arrow). d The relative pressure map reveals higher pressure in the transvers sinus (white arrow) compared to the stenotic segment and distal sigmoid sinus
