Validation and noise robustness assessment of microscopic anisotropy estimation with clinically feasible double diffusion encoding MRI
Leevi Kerkelä, Rafael Neto Henriques, Matt G. Hall +2
Purpose: Double diffusion encoding (DDE) MRI enables the estimation of microscopic diffusion anisotropy, yielding valuable information on tissue microstructure. A recent study prop…
Correlation Tensor Magnetic Resonance Imaging
Rafael Neto Henriques, Sune Nørhøj Jespersen, Noam Shemesh
Diffusional Kurtosis Imaging (DKI) is a sensitive biomarker for microstructure in health and disease. However, DKI is not specific to any microstructural property since it may emer…
SANDI: a compartment-based model for non-invasive apparent soma and neurite imaging by diffusion MRI
Marco Palombo, Andrada Ianus, Daniel Nunes +4
This work introduces a compartment-based model for apparent soma and neurite density imaging (SANDI) using non-invasive diffusion-weighted MRI (DW-MRI). The existing conjecture in…
Short echo time relaxation-enhanced MR spectroscopy reveals broad downfield resonances
Sónia I. Gonçalves, Clémence Ligneul, Noam Shemesh
Purpose: Most MR spectroscopy (MRS) pulse sequences rely on broadband excitation with water saturation and typically focus on upfield signals. By contrast, the downfield spectrum,…
Evaluation of principal component analysis image denoising on multi-exponential MRI relaxometry
Mark D. Does, Jonas Lynge Olesen, Kevin D. Harkins +4
PURPOSE: Multi-exponential relaxometry is a powerful tool for characterizing tissue, but generally requires high image signal-to-noise ratio (SNR). This work evaluates the use of p…
Microscopic anisotropy misestimation in spherical-mean single diffusion encoding MRI
Rafael Neto Henriques, Sune N Jespersen, Noam Shemesh
Purpose: Microscopic fractional anisotropy (μFA) can disentangle microstructural information from orientation dispersion. While double diffusion encoding (DDE) MRI methods are wide…
