Brain wide pathway for waste clearance captured by contrast enhanced MRI

Helene Benveniste of Stony Brook University discusses the use of contrastenhanced MRI to visualize the glymphatic system, a paravascular pathway that facilitates the clearance of waste and solutes from the cerebrospinal fluid and interstitial fluid of the brain. Glymphatic pathway function can be measured using dynamic contrastenhanced MRI. Benveniste and colleagues used whole brain imaging to identify, confirm key features of the glymphatic pathway in rats. Many degenerative brain diseases are ass
