Analysis of White Matter Damage in Patients with Multiple Sclerosis via a Novel In Vivo MR Method for Measuring Myelin, Axons, and G-Ratio
Akifumi Hagiwara,Masaaki Hori,Kazumasa Yokoyama,Misaki Nakazawa,Ryo Ueda,Moeko Horita,Christina Andica,Osamu Abe,Shigeki Aoki +8 more
TL;DR: The myelin of WM was more damaged than axons in plaques and periplaque WM of patients with MS, and myelin and axon volume fractions and g-ratio may potentially be useful for evaluating WM damage in Patients with MS.

Microstructural Damage in Normal-Appearing Brain Parenchyma and Neurocognitive Dysfunction in Adult Moyamoya Disease
Shoko Hara,Shoko Hara,Masaaki Hori,Syo Murata,Ryo Ueda,Ryo Ueda,Yoji Tanaka,Motoki Inaji,Taketoshi Maehara,Shigeki Aoki,Tadashi Nariai +10 more
TL;DR: Chronic ischemia in MMD may decrease the axon density in the white matter and dendritedensity in the cortex (Vic) and simplify network complexity (OD), leading to neurocognitive dysfunction.

The Relationship between Neurite Density Measured with Confocal Microscopy in a Cleared Mouse Brain and Metrics Obtained from Diffusion Tensor and Diffusion Kurtosis Imaging.
Ryusuke Irie,Ryusuke Irie,Koji Kamagata,Aurelien Kerever,Ryo Ueda,Suguru Yokosawa,Yosuke Otake,Hisaaki Ochi,Hidekazu Yoshizawa,Ayato Hayashi,Kazuhiko Tagawa,Hitoshi Okazawa,Kohske Takahashi,Kanako Sato,Masaaki Hori,Eri Arikawa-Hirasawa,Shigeki Aoki +16 more
TL;DR: DKI accurately reflected neurite density in the area with crossing fibers, potentially allowing evaluation of complex microstructures and correlations between diffusion metrics and neuritedensity were analyzed.

Correlation analysis of motor function improvement and brain structure for upper limb paralysis.
TL;DR: It is considered that the cortical thickness of the postcentral gyrus or the supramarginal gyrus of the affected hemisphere plays an important role in such recovery in poststroke hemiparetic patients.

Ventricular volumetry and free-water corrected diffusion tensor imaging of the anterior thalamic radiation in idiopathic normal pressure hydrocephalus.
Asami Saito,Asami Saito,Koji Kamagata,Ryo Ueda,Misaki Nakazawa,Christina Andica,Ryusuke Irie,Madoka Nakajima,Masakazu Miyajima,Masaaki Hori,Fumiaki Tanaka,Hajime Arai,Shigeki Aoki +12 more
TL;DR: Third ventricular volume was significantly decreased after shunting; its volume reduction negatively correlated with a neuropsychological improvement; and FW imaging possibly provides better white matter characterization in iNPH.
