Elucidating the complex organization of neural micro-domains in the locust Schistocerca gregaria using dMRI

Scientific Reports, 2021
To understand brain function it is necessary to characterize both the underlying structural connectivity between neurons and the physiological integrity of these connections.

Cardiac diffusion kurtosis imaging in the human heart in vivo using 300 mT/m gradients. [PDF]

Magn Reson Med
Purpose Diffusion tensor imaging (DTI) is commonly used in cardiac diffusion magnetic resonance imaging (dMRI). However, the tissue's microstructure (cells, membranes, etc.) restricts the movement of the water molecules, making the spin displacements ...

Investigating the relationship between diffusion kurtosis tensor imaging (DKTI) and histology within the normal human brain

Scientific Reports, 2021
Measurements of water diffusion with MRI have been used as a biomarker of tissue microstructure and heterogeneity. In this study, diffusion kurtosis tensor imaging (DKTI) of the brain was undertaken in 10 healthy volunteers at a clinical field strength ...

Combined Application of Quantitative Susceptibility Mapping and Diffusion Kurtosis Imaging Techniques to Investigate the Effect of Iron Deposition on Microstructural Changes in the Brain in Parkinson’s Disease

Frontiers in Aging Neuroscience, 2022
ObjectivesBrain iron deposition and microstructural changes in brain tissue are associated with Parkinson’s disease (PD). However, the correlation between these factors in Parkinson’s disease has been little studied.
