Individual values of aqueductal CSF stroke volume (aqSV) in 147 patients with chronic adult hydrocephalus with high (left) and low (right) burden of enlarged perivascular spaces (ePVS). The dotted lines represent median values. Patients with low ePVS burden (less than 11 ePVS at both basal ganglia and periventricular parenchyma) had significantly higher median aqSV (p = 0.02, adjusted for multiple comparisons) than patients with high ePVS burden (at least 11 ePVS or more at both basal ganglia and periventricular parenchyma).
