WebJan 1, 2013 · Three-dimensional probability distribution of diffusivity can be described by a diffusion tensor ellipsoid with three eigenvectors and the corresponding eigenvalues (λ 1, λ 2, and λ 3). The eigenvector associated with the largest eigenvalue denotes the predominant orientation of fibers in a given imaging voxel. WebJun 29, 2024 · Diffusion-weighted imaging (DWI) is a well-established magnetic resonance imaging (MRI) method for diagnosing cerebral ischemia. DWI is a routine protocol in most institutions that perform neuroimaging; normal states and abnormal conditions are easily interpreted through the use of DWI in conjunction with the use of apparent diffusion ... la mex in joliet
