A3: A3 segment of the anterior cerebral artery; CV: coefficient of variation; NA: not available; MO: mobility; M1: M1 segment of the middle cerebral artery; PVS: Perivascular space; P1: P1 segment of the posterior cerebral artery; P2: P2 segment of the posterior cerebral artery; SD: standard deviation; SSS: Superior sagittal sinus.

^*p value at each ROI was calculated by the paired samples t-test compared against the ROI of the anterior horn of lateral ventricle.
