Brain-wide pathways of perivascular flow help clear the brain of proteins and metabolic waste linked to the onset and progression of neurodegenerative diseases. Recent studies on the glymphatic system and novel lymphatic vessels of the meninges have prompted new insight into the clinical significance of perivascular flow. Current techniques in both humans and animals are unable to fully reveal the complex functional and anatomical features of these clearance pathways. While much research has stemmed from fluorescence microscopy and MR imaging, clinical and experimental investigations are hindered by the lack of more advanced and precise technology. In this review, we discuss the biological relevance of the glymphatic and perivascular clearance systems, the innovative technology that has defined these pathways, and the potential for new studies to advance our understanding of degenerative brain diseases using similar technology.
