Autor: Bryony L McGarry, Robin A Damion, Isabel Chew, Michael J Knight, George WJ Harston, Davide Carone, Peter Jezzard, Amith Sitaram, Keith W Muir, Philip Clatworthy, Risto A Kauppinen
Publikováno v: Journal of Central Nervous System Disease, Vol 12 (2020)
Background: T 2 relaxation-based magnetic resonance imaging (MRI) signals may provide onset time for acute ischemic strokes with an unknown onset. The ability of visual and quantitative MRI-based methods in a cohort of hyperacute ischemic stroke pati

Orthogonal invariant sets of the diffusion tensor and the development of a curvilinear set suitable for low-anisotropy tissues.
Autor: Robin A Damion, Aleksandra Radjenovic, Eileen Ingham, Zhongmin Jin, Michael E Ries
Publikováno v: PLoS ONE, Vol 8, Iss 11, p e78798 (2013)
We develop a curvilinear invariant set of the diffusion tensor which may be applied to Diffusion Tensor Imaging measurements on tissues and porous media. This new set is an alternative to the more common invariants such as fractional anisotropy and t
