POAS4SPM: a toolbox for SPM to denoise diffusion MRI data [PDF]

, 2013
We present an implementation of a recently developed noise reduction algorithm for dMRI data, called multi-shell position orientation adaptive smoothing (msPOAS), as a toolbox for SPM.

Mini Review on Anomalous Diffusion by MRI: Potential Advantages, Pitfalls, Limitations, Nomenclature, and Correct Interpretation of Literature

Frontiers in Physics, 2020
In this mini-review, we addressed the transient-anomalous diffusion by MRI, starting from the assumption that transient-anomalous diffusion is ubiquitously observed in biological tissues, as demonstrated by different single-particle-tracking optical ...

Renal MRI Diffusion: Experimental Protocol [PDF]

, 2021
AbstractRenal diffusion-weighted imaging (DWI) can be used to obtain information on the microstructure of kidney tissue, and has the potential to provide MR-biomarkers for functional renal imaging. Here we describe in a step-by-step experimental protocol the MRI method for measuring renal diffusion coefficients in rodents using ADC or IVIM models. Both

Multi-centre reproducibility of diffusion MRI parameters for clinical sequences in the brain. [PDF]

, 2015
The purpose of this work was to assess the reproducibility of diffusion imaging, and in particular the apparent diffusion coefficient (ADC), intra-voxel incoherent motion (IVIM) parameters and diffusion tensor imaging (DTI) parameters, across multiple ...

Pore size estimation from double diffusion encoding

Current Directions in Biomedical Engineering, 2017
Double diffusion encoding is a magnetic resonance technique with applications in measuring microstructure. In many tissues, cell size (which is of a few micrometers) is an important biological parameter.

Longitudinal measurement of the developing grey matter in preterm subjects using multi-modal MRI. [PDF]

, 2015
Preterm birth is a major public health concern, with the severity and occurrence of adverse outcome increasing with earlier delivery. Being born preterm disrupts a time of rapid brain development: in addition to volumetric growth, the cortex folds ...

Gibbs ringing in diffusion MRI [PDF]

Magnetic Resonance in Medicine, 2015
PurposeTo study and reduce the effect of Gibbs ringing artifact on computed diffusion parameters.MethodsWe reduce the ringing by extrapolating the k‐space of each diffusion weighted image beyond the measured part by selecting an adequate regularization term. We evaluate several regularization terms and tune the regularization parameter to find the best
