Outline of Final Research Achievements

We were able to indicate the leakage of Gadolinium-based contrast agent (GBCA) into the subarachnoid space around the cortical veins with MRI obtained after intravenous injection of GBCA.And intravenously administered GBCA leaks into the subarachnoid space around the cortical veins in most patients over 37 years of age. However, it should be noted that it can be found occasionally in patients under 37 years of age.

Academic Significance and Societal Importance of the Research Achievements

脳内のGlymphaticシステムの評価ができることによる臨床的あるいは社会的な利益はきわめて大きいと考えられる。Glymphatic システムは哺乳動物の中枢神経系の廃棄物の排出経路と考えられており、このシステムの解明はアルツハイマー病、パーキンソン病などでの高次脳機能などの障害の病態解明につながる可能性がある。今回このシステムの年齢による機能変化をみることができ、今後これらの疾患や加齢による影響の解明にもつながる可能性があると考えられる。
