Journal ArticleDOI
Diffusion tractography of the fornix in schizophrenia.
Jennifer Fitzsimmons,Marek Kubicki,Marek Kubicki,K. Smith,Georgia B. Bushell,R. San Jose Estepar,Carl-Fredrik Westin,Paul G. Nestor,Margaret A. Niznikiewicz,Ron Kikinis,Robert W. McCarley,Martha E. Shenton,Martha E. Shenton +12 more
TL;DR: The utility of applying DTI and tractography to study white matter fiber tracts in vivo in schizophrenia is shown, with a bilateral disruption in fornix integrity in schizophrenia observed, thus broadening the understanding of the pathophysiology of this disease.
Journal ArticleDOI
P300 in schizophrenia: Confirmation and statistical validation of temporal region deficit in P300 topography☆
Steven F. Faux,Steven F. Faux,Steven F. Faux,Michael W. Torello,Michael W. Torello,Michael W. Torello,Robert W. McCarley,Robert W. McCarley,Robert W. McCarley,Martha E. Shenton,Martha E. Shenton,Martha E. Shenton,Frank H. Duffy,Frank H. Duffy,Frank H. Duffy +14 more
TL;DR: Comparison of normal and medicated schizophrenic groups on the auditory P300 component of the event-related potential confirmed the earlier finding of a left temporal deficit in P300 amplitude in schizophrenia.
Book ChapterDOI
A unifying approach to registration, segmentation, and intensity correction
Kilian M. Pohl,John W. Fisher,James J. Levitt,Martha E. Shenton,Ron Kikinis,W. Eric L. Grimson,William M. Wells +6 more
TL;DR: A statistical framework that combines the registration of an atlas with the segmentation of magnetic resonance images is presented, and it is shown that the approach performs better than similar methods which separate the registration and segmentation problems.
Journal ArticleDOI
Increased gray matter diffusion anisotropy in patients with persistent post-concussive symptoms following mild traumatic brain injury.
Sylvain Bouix,Ofer Pasternak,Yogesh Rathi,Paula E. Pelavin,Ross Zafonte,Ross Zafonte,Martha E. Shenton,Martha E. Shenton +7 more
TL;DR: A novel analysis method was developed to identify abnormalities in high-resolution diffusion tensor imaging (DTI) when the location of brain injury is heterogeneous across subjects and subject-specific profiles provide important information regarding the pathology associated with PPCS.
Journal ArticleDOI
Hockey Concussion Education Project, Part 2. Microstructural white matter alterations in acutely concussed ice hockey players: a longitudinal free-water MRI study
Ofer Pasternak,Inga K. Koerte,Inga K. Koerte,Sylvain Bouix,Eli Fredman,Takeshi Sasaki,Takeshi Sasaki,Michael Mayinger,Michael Mayinger,Karl G. Helmer,Andrew M. Johnson,Jeffrey D. Holmes,Lorie A. Forwell,Elaine N. Skopelja,Martha E. Shenton,Martha E. Shenton,Paul S. Echlin +16 more
TL;DR: Concussion during ice hockey games results in microstructural alterations that are detectable using dMRI, and the alterations that the authors found suggest decreased extracellular space and decreased diffusivities in white matter tissue.
