Researchers will compare the MRI findings before and after embolization to explore whether treatment is associated with changes in glymphatic-related brain imaging markers.",[26,27],"Dural Arteriovenous Fistula","Glymphatic System",[29,30,27,26],"MRI","DTI","RECRUITING","2026-09-10",{"date":34,"type":35},"2026-09-17","ACTUAL",{"date":37,"type":35},"2026-01-01",{"date":39,"type":22},"2029-08-01",{"name":41,"class":42},"Hospital Universitari Vall d'Hebron Research Institute","OTHER",3]
