Using Diffusion-Diffusion Exchange Spectroscopy to observe diffusion exchange in yeast

Autor: Breen-Norris, James O, Siow, Bernard, Hipwell, Ben, Roberts, Thomas, Lythgoe, Mark F., Ianus, Andrada, Alexander, Daniel C., Walker-Samuel, Simon

The permeability of cell membranes varies significantly across both healthy and diseased tissue, and changes in cell membrane permeability can occur during treatment response in tumours. Measurements of cell membrane permeability could therefore be u

Axon radius estimation with Oscillating Gradient Spin Echo (OGSE) diffusion MRI

Autor: Siow, Bernard, Drobnjak, Ivana, Ianus, Andrada, Christie, Isabel N., Lythgoe, Mark F., Alexander, Daniel C.

Publikováno v: Diffusion fundamentals. 18(1):1-6

The estimation of axon radius provides insights into brain function [1] and could provide progression and classification biomarkers for a number of white matter diseases [2-4]. A recent in silico study [5] has shown that optimised gradient waveforms

The value of preclinical diffusion MRI (dMRI) is substantial. While dMRI enables in vivo non-invasive characterization of tissue, ex vivo dMRI is increasingly used to probe tissue microstructure and brain connectivity. Ex vivo dMRI has several experi

Tensor denoising of high-dimensional MRI data

Autor: Olesen, Jonas L., Ianus, Andrada, Østergaard, Leif, Shemesh, Noam, Jespersen, Sune N.

The signal to noise ratio (SNR) fundamentally limits the information accessible by magnetic resonance imaging (MRI). This limitation has been addressed by a host of denoising techniques, recently including so-called MPPCA: Principal component analysi

Publikováno v: Journal of Neuroscience Methods (2020)

Diffusion Magnetic Resonance Imaging (dMRI) is one of the most important contemporary non-invasive modalities for probing tissue structure at the microscopic scale. The majority of dMRI techniques employ standard single diffusion encoding (SDE) measu

SANDI: a compartment-based model for non-invasive apparent soma and neurite imaging by diffusion MRI

Autor: Palombo, Marco, Ianus, Andrada, Nunes, Daniel, Guerreri, Michele, Alexander, Daniel C., Shemesh, Noam, Zhang, Hui

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 brain microstructure imaging trough DW-MRI presents water diffusion in
