Measurements of venous oxygen saturation in the superior sagittal sinus using conventional 3D multiple gradient‐echo MRI: Effects of flow velocity and acceleration
Abstract:Purpose
This work investigates the effects of flow acceleration in the superior sagittal sinus on slice‐dependent variations in venous oxygen saturation (SvO2) estimations using susceptibility‐based MR oximetry.
Methods
Three‐dimensional multiple gradient‐echo images, with first‐order flow compensation along the anterior–posterior readout direction for the first echo, were acquired twice from 15 healthy volunteers. For all slices, phases within the superior sagittal sinus were fitted using linear regression ac… Show more
