Journal ArticleDOI
Quantitative evaluation of 10 tractography algorithms on a realistic diffusion MR phantom.
Pierre Fillard,Maxime Descoteaux,Alvina Goh,Sylvain Gouttard,Ben Jeurissen,James G. Malcolm,Alonso Ramirez-Manzanares,Marco Reisert,Kenneth Earl Sakaie,F. Tensaouti,Ting Yo,Jean-François Mangin,Cyril Poupon +12 more
TL;DR: A common dataset with known ground truth and a reproducible methodology to quantitatively evaluate the performance of various diffusion models and tractography algorithms is used and evidence that diffusion models such as (fiber) orientation distribution functions correctly model the underlying fiber distribution is provided.
Journal ArticleDOI
Filtered Multitensor Tractography
TL;DR: A technique that uses tractography to drive the local fiber model estimation as recursive estimation that significantly improves the angular resolution at crossings and branchings and confirms the ability to trace through regions known to contain such crossing and branching while providing inherent path regularization.
Journal ArticleDOI
Complications following cranioplasty and relationship to timing: A systematic review and meta-analysis.
James G. Malcolm,Rima S. Rindler,Jason Chu,Jonathan A. Grossberg,Gustavo Pradilla,Faiz U. Ahmad +5 more
TL;DR: Early cranioplasty within 90days after decompressive craniectomy is associated with an increased odds of hydrocephalus than with later craniplasty, but no difference in odds of developing other complications.
Proceedings ArticleDOI
Graph Cut Segmentation with Nonlinear Shape Priors
TL;DR: It is demonstrated how a shape projection pre-image can induce an iteratively refined shape prior in a Bayesian manner using kernel principle component analysis.
Journal ArticleDOI
Early Cranioplasty is Associated with Greater Neurological Improvement: A Systematic Review and Meta-Analysis
James G. Malcolm,Rima S. Rindler,Jason Chu,Falgun H. Chokshi,Jonathan A. Grossberg,Gustavo Pradilla,Faiz U. Ahmad +6 more
TL;DR: Cranioplasty may improve neurological function, and earlier cranioplasty may enhance this effect, and future prospective studies evaluating long-term, comprehensive neurological outcomes will be required to establish the true effect of crANIoplasty on neurological outcome.
