1 Relationship between Diffusion Tensor Fractional Anisotropy and Motor Outcome in Patients with Hemiparesis after Corona Radiata Infarct  Tetsuo Koyama, MD, PhD, Kohei Marumoto, MD, Hiroji Miyake, MD, PhD, Kazuhisa Domen, MD, PhD  Journal of Stroke and Cerebrovascular Diseases  Volume 22, Issue 8, Pages (November 2013) DOI: /j.jstrokecerebrovasdis Copyright © 2013 National Stroke Association Terms and Conditions

2 Figure 1 Region of interest is shown in white. Abbreviations: L, left; R, right. Journal of Stroke and Cerebrovascular Diseases  , DOI: ( /j.jstrokecerebrovasdis ) Copyright © 2013 National Stroke Association Terms and Conditions

3 Figure 2 Diffusion-weighted images and diffusion tensor imaging-fractional anisotropy images of cerebral peduncles. Arrowheads indicate ischemic lesions within the corona radiata. Abbreviation: rFA, ratio of fractional anisotropy in affected and unaffected hemispheres within the region of interest.
