Quantification of Perivascular Flow Dynamics of Human Cerebrospinal Fluid Along Major Arteries Using Phase-Contrast MRI

< .001) of the perivascular CSF velocity curve in the distal cortical branches of the MCA differed between the two age groups. Conclusion A semiautomated pipeline of algorithms using phase-contrast MRI was developed to locate and quantify age-dependent human CSF dynamics along the perivascular spaces of major brain arteries. © RSNA, 2025
