Journal ArticleDOI
Diffusion Tensor Imaging of the Brain
TL;DR: Diffusion tensor imaging (DTI) is a promising method for characterizing microstructural changes or differences with neuropathology and treatment and the biological mechanisms, acquisition, and analysis of DTI measurements are addressed.
Journal ArticleDOI
Analysis of partial volume effects in diffusion‐tensor MRI
TL;DR: A partial volume model of MRI signal behavior for two diffusion‐tensor compartments is presented andSimulations using this model demonstrate that the conventional single diffusion tensor model could lead to highly variable and inaccurate measurements of diffusion behavior.
Journal Article
Diffusion tensor imaging of cerebral white matter: a pictorial review of physics, fiber tract anatomy, and tumor imaging patterns.
Brian J. Jellison,Aaron S. Field,Joshua Medow,Mariana Lazar,M Shariar Salamat,Andrew L. Alexander +5 more
TL;DR: The normal anatomy of the white matter (WM) tracts as they appear on directional diffusion tensor imaging (DTI) color maps, which will almost certainly be available to the general radiologist as part of a commercial DTI software package in the near future.
Journal ArticleDOI
White matter tractography using diffusion tensor deflection.
Mariana Lazar,David M. Weinstein,Jay S. Tsuruda,Khader M. Hasan,Konstantinos Arfanakis,M. Elizabeth Meyerand,Benham Badie,Howard A. Rowley,Victor M. Haughton,Aaron S. Field,Andrew L. Alexander +10 more
TL;DR: Simulations show that the deflection term is less sensitive than the major eigenvector to image noise and is promising for mapping the organizational patterns of white matter in the human brain as well as mapping the relationship between major fiber trajectories and the location and extent of brain lesions.
Journal ArticleDOI
Diffusion tensor imaging of the corpus callosum in Autism
Andrew L. Alexander,Jee Eun Lee,Mariana Lazar,Rebecca Boudos,Molly B. DuBray,Terrence R. Oakes,Judith Miller,Jeffrey K. Lu,Eun Kee Jeong,William M. McMahon,Erin D. Bigler,Janet E. Lainhart +11 more
TL;DR: The results suggest that the microstructure of the corpus callosum is affected in autism, which may be related to nonverbal cognitive performance.
