Fig. 1

Anatomical depiction of the landmarks used to delineate parasagittal dural (PSD) space (green) and intravenous arachnoid granulations (AG) (blue), venous lumen (red). Sketch illustrating localization and morphology of the peri-sinus structures (A). Coronal view displaying medium-sized AG and enlargement of the parasagittal dural space (B-1,2,3). Coronal view showing large AG and small enlargement of PSD (C-1,2,3). PSD appears as intermediate T2-weighted signal above a layer of dura mater (i.e., hypointense T2 signal) and subarachnoid space (i.e., hyperintense T2 signal)
