FIG 1. Illustration of flow measurement in the SSS.
A, Slice plane to obtain velocity and magnitude images was placed just above the confluens sinuum and perpendicular to the SSS on a midsagittal T1-weighted image (33/24/2 [TR/TE/excitations]; 20° flip angle).
B, An ROI was manually drawn outlining the SSS on the magnitude images (35/12/2; 20° flip angle). In addition, a background ROI to correct flow velocity was placed in one of the occipital lobes, avoiding vessels and CSF.
