Neurite orientation dispersion and density imaging reveals white matter microstructural alterations in adults with autism
Autor: Christina Andica, Koji Kamagata, Eiji Kirino, Wataru Uchida, Ryusuke Irie, Syo Murata, Shigeki Aoki
Publikováno v: Molecular Autism, Vol 12, Iss 1, Pp 1-14 (2021)
Abstract Background Evidences suggesting the association between behavioral anomalies in autism and white matter (WM) microstructural alterations are increasing. Diffusion tensor imaging (DTI) is widely used to infer tissue microstructure. However, d

Diffusion imaging of reversible and irreversible microstructural changes within the corticospinal tract in idiopathic normal pressure hydrocephalus
Autor: Kouhei Kamiya, Masaaki Hori, Ryusuke Irie, Masakazu Miyajima, Madoka Nakajima, Koji Kamagata, Kouhei Tsuruta, Asami Saito, Misaki Nakazawa, Yuichi Suzuki, Harushi Mori, Akira Kunimatsu, Hajime Arai, Shigeki Aoki, Osamu Abe
Publikováno v: NeuroImage: Clinical, Vol 14, Iss C, Pp 663-671 (2017)
The symptoms of idiopathic normal pressure hydrocephalus (iNPH) can be improved by shunt surgery, but prediction of treatment outcome is not established. We investigated changes of the corticospinal tract (CST) in iNPH before and after shunt surgery
