The venous drainage system may be influenced by the blood outflow resistance. Precise quantitative measurements of intracranial venous resistance are few. Phase-contrast (PC) MR angiography was used to quantify vascular resistance (VR) of the global cerebral venous system and to explore the correlations between the estimated resistances and the venous outflows measured by cine phase contrast (PC) MRI. Twenty six healthy volunteers participated in this study. The sum of resistances of the transverse sinus, sigmoid sinus and jugular vein correlated with the blood flows measured at C2C3 level: left R² =0.39 and right R² = 0.40 .
