Estimating structural connectivity from diffusion-weighted magnetic resonance imaging is a challenging task, partly due to the presence of false-positive connections and the misestimation of connection weights. Building on previous efforts, the MICCA

Mapping brain–behavior networks using functional and structural connectome fingerprinting in the HCP dataset

Autor: Ying‐Chia Lin, Steven H Baete, Xiuyuan Wang, Fernando E Boada

Publikováno v: Brain and Behavior, Vol 10, Iss 6, Pp n/a-n/a (2020)

Abstract Introduction Connectome analysis of the human brain's structural and functional architecture provides a unique opportunity to understand the organization of the brain's functional architecture. In previous studies, connectome fingerprinting

Performance of orientation distribution function‐fingerprinting with a biophysical multicompartment diffusion model

Autor: Patryk Filipiak, Timothy Shepherd, Ying‐Chia Lin, Dimitris G. Placantonakis, Fernando E. Boada, Steven H. Baete

Publikováno v: Magn Reson Med

PURPOSE: Orientation Distribution Function (ODF) peak finding methods typically fail to reconstruct fibers crossing at shallow angles below 40 degrees, leading to errors in tractography. ODF-Fingerprinting (ODF-FP) with the biophysical multicompartme

A Path to Qualification of PET/MRI Scanners for Multicenter Brain Imaging Studies: Evaluation of MRI-Based Attenuation Correction Methods Using a Patient Phantom

Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine, vol 63, iss 4

Positron emission tomography and magnetic resonance imaging (PET/MRI) scanners cannot be qualified in the manner adopted for hybrid PET and computed tomography (CT) devices. The main hurdle with qualification in PET/MRI is that attenuation correction

Stepwise Stochastic Dictionary Adaptation Improves Microstructure Reconstruction with Orientation Distribution Function Fingerprinting

Autor: Patryk Filipiak, Timothy Shepherd, Lee Basler, Anthony Zuccolotto, Dimitris G. Placantonakis, Walter Schneider, Fernando E. Boada, Steven H. Baete

Publikováno v: Computational Diffusion MRI ISBN: 9783031212055
CDMRI Workshop (2022)

Fitting of the multicompartment biophysical model of white matter is an ill-posed optimization problem. One approach to make it computationally tractable is through Orientation Distribution Function (ODF) Fingerprinting. However, the accuracy of this

Fingerprinting Orientation Distribution Functions in diffusion MRI detects smaller crossing angles

Autor: Dimitris G. Placantonakis, Fernando E. Boada, Martijn A. Cloos, Ying-Chia Lin, Timothy M. Shepherd, Steven H. Baete

Publikováno v: Neuroimage

Diffusion tractography is routinely used to study white matter architecture and brain connectivity in vivo. A key step for successful tractography of neuronal tracts is the correct identification of tract directions in each voxel. Here we propose a f
