报告题目：both the parenchymal venous system and the glymphatic system participate in cerebral waste removal
impaired cerebral waste clearance (cwc) has been associated with a broad range of both physiological and pathophysiological neurologic conditions, making it a focus-of-interest and an important area of study. because of the unique anatomy of the brain parenchyma, theoretically, in the brain parenchyma, biochemically inert waste such as mri contrast agents can only be removed through two possible pathways: cerebrospinal fluid (csf) pathway, and/or vascular pathway. despite controversy, there seems to be a solid consensus on the participation of the csf pathway in cwc. in contrast to the csf system, the current consensus is that parenchymal vascular system does not participate in cwc. considering there is a big difference in flow rate between the blood (2 ml/min) and the csf (3.7 µl/min) and the brain is the most bioactive, energy-consuming organ (20% nutrition for about 5% of body weight) in the body, it is illogical that the brain would rely on the slow csf circulation for cwc while less bioactive tissues outside the brain require both the fast vascular and slow lymphatic systems (which has the similar circulation speed as csf) to remove waste in a timely manner. here we present our results to demonstrate the participation of the parenchymal venous system in cwc using the qualitative and quantitative superparamagnetic iron oxide (spio)-enhanced susceptibility weighted imaging (swi), spio-swi methods.
