Angular Upsampling in Infant Diffusion MRI Using Neighborhood Matching in x-q Space [PDF]
Frontiers in Neuroinformatics, 2018 Diffusion MRI requires sufficient coverage of the diffusion wavevector space, also known as the q-space, to adequately capture the pattern of water diffusion in various directions and scales.

Diffusion MRI with Machine Learning. [PDF]
Imaging Neurosci (Camb)Abstract Diffusion-weighted magnetic resonance imaging (dMRI) of the brain offers unique capabilities including noninvasive probing of tissue microstructure and structural connectivity. It is widely used for clinical assessment of disease and injury, and for neuroscience research. Analyzing the dMRI data to extract useful information for

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

Diffusion MRI of the Hippocampus
The Journal of Neuroscience, 2023 The hippocampus is a brain structure that plays key roles in a variety of cognitive processes. Critically, a wide range of neurological disorders are associated with degeneration of the hippocampal microstructure, defined as neurons, dendrites, glial cells, and more.

Diffusion tensor MRI phantom exhibits anomalous diffusion [PDF]
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014 This paper reports diffusion weighted MRI measurements of cyclohexane in a novel diffusion tensor MRI phantom composed of hollow coaxial electrospun fibers (average diameter 10.2 μm). Recent studies of the phantom demonstrated its potential as a calibration standard at low b values (less than 1000 s/mm2) for mean diffusivity and fractional anisotropy ...
