(A, reconstructed 3D-DRIVE in sagittal plane) ECG-gated quantitative PC was acquired perpendicular to the long axis of the shunt catheter at the suboccipital region distal to its valve. B A ROI was drawn over the inner diameter of the shunt tube in axial re-phased image. C CSF flow curve and velocity parameters were calculated by CSF-QF software
