Computation of eigenvalue and eigenvector derivatives for a general complex-valued eigensystem
TL;DR: In this paper, a method for computing first order derivatives of the eigenvalues and eigenvectors for a general complex-valued, non-defective matrix is presented.
Journal ArticleDOI
"MASSIVE" Brain Dataset : Multiple Acquisitions for Standardization of Structural Imaging Validation and Evaluation
TL;DR: The MASSIVE (Multiple Acquisitions for Standardization of Structural Imaging Validation and Evaluation) brain dataset of a single healthy subject is presented, which is intended to facilitate diffusion MRI (dMRI) modeling and methodology development.

TL;DR: The morphology scores of cognitively normal subjects are on average lower than the scores of AD subjects, indicating that morphology differences between AD subjects and healthy subjects can be partly explained by accelerated aging.

TL;DR: The best performing IVIM fit algorithm was IVM-Bayesian-lin, but an easier to implement least squares fit with fixed D* performs similarly in pancreatic cancer patients.
Motion correction and parameter estimation in dceMRI sequences: Application to colorectal cancer
TL;DR: In this paper, a novel Bayesian framework for non-rigid motion correction and pharmacokinetic parameter estimation in dceMRI sequences is presented, which incorporates a physiological image formation model into the similarity measure used for motion correction.

Nonrigid registration using free-form deformations: application to breast MR images
TL;DR: The results clearly indicate that the proposed nonrigid registration algorithm is much better able to recover the motion and deformation of the breast than rigid or affine registration algorithms.

Probabilistic diffusion tractography with multiple fibre orientations: What can we gain?
TL;DR: It is shown that multi-fibre tractography offers significant advantages in sensitivity when tracking non-dominant fibre populations, but does not dramatically change tractography results for the dominant pathways.
