Outline of Annual Research Achievements

アルツハイマー病とグリンパティック系の障害の関連に関して、DTI-ALPS法での検討を行った。拡散テンソル法で得られた3次元拡散のデータセットから血管周囲腔の方向の拡散成分の比を算出し、アルツハイマー病でこの比が低下することを、Taoka T. et al. Evaluation of glymphatic system activity with the diffusion MR technique: diffusion tensor image analysis along the perivascular space (DTI-ALPS) in Alzheimer's disease cases. Jpn J Radiol. 2017;35:172-178.で報告した。また、複数のジャーナルからのinvited review articleを出版する機会を得た。Glymphaticシステムの構造的な基礎となる血管周囲腔の構造に関しての招待総説Taoka T. et al. Structure of the Medullary Veins of the Cerebral Hemisphere and Related Disorders. Radiographics. 2017;37:281-297を出版したほか、ガドリニウム造影剤の脳内沈着に関して、Glymphaticシステムとの関連を考察した招待総説Taoka T. et al. Gadolinium-based Contrast Media, Cerebrospinal Fluid and the Glymphatic System: Possible Mechanisms for the Deposition of Gadolinium in the Brain. Magn Reson Med Sci. 2018;17:111-119.を2018年に出版した。また、招待総説Taoka T. et al. Glymphatic imaging using MRI. J Magn Reson Imaging. 2020;51:11-24.では、Glymphaticシステム/Neurofluids動態の画像評価に関して包括的なまとめをした。
