Spatially selective 2D RF inner field of view (iFOV) diffusion kurtosis imaging (DKI) of the pediatric spinal cord [PDF]

NeuroImage: Clinical, 2016
Magnetic resonance based diffusion imaging has been gaining more utility and clinical relevance over the past decade. Using conventional echo planar techniques, it is possible to acquire and characterize water diffusion within the central nervous system (

Characterization of Breast Tumors Using Diffusion Kurtosis Imaging (DKI) [PDF]

PLoS ONE, 2014
The aim of this study was to investigate and evaluate the role of magnetic resonance (MR) diffusion kurtosis imaging (DKI) in characterizing breast lesions.One hundred and twenty-four lesions in 103 patients (mean age: 57 ± 14 years) were evaluated by MR DKI performed with 7 b-values of 0, 250, 500, 750, 1,000, 1,500, 2,000 s/mm2 and dynamic contrast ...

The Association of Apparent Myelin Water Fraction With Diffusional Kurtosis and Biophysical Modeling Parameters. [PDF]

NMR Biomed
We investigated associations between a panel of diffusion MRI metrics and myelin content, using ViSTa apparent myelin water fraction (aMWF) as a proxy for myelin. Fractional anisotropy (FA) showed a robust association with aMWF; however, more advanced metrics including radial kurtosis (K⊥) and axonal water fraction (f) had stronger correlations ...

Diffusion MRI reveals amyloid plaque–associated cellular signatures through spatial transcriptomic integration [PDF]

Alzheimers Dement
Abstract INTRODUCTION Amyloid plaque deposition is a defining feature of Alzheimer's disease (AD), yet how plaque‐associated cellular alterations are reflected in noninvasive imaging remains unclear. METHODS We integrated high‐resolution diffusion magnetic resonance imaging (dMRI) with spatial transcriptomics (ST) in an AD mouse model.

High-Resolution Diffusion Kurtosis Imaging of Hippocampus Subfields Across the Healthy Lifespan. [PDF]

NMR Biomed
Developmental and aging changes were examined in the hippocampus using 1 mm isotropic diffusion kurtosis imaging in 363 participants aged 5–90 years. HippUnfold enabled automated subfield segmentation and unfolded hippocampal maps. Whole‐hippocampus showed distinct lifespan trajectories: volume, quadratic; MD, negative Gamma Variate; FA, positive Gamma

Widespread White Matter Microstructure Alterations Based on Diffusion Tensor Imaging and Diffusion Kurtosis Imaging in Patients With Pontine Infarction

Frontiers in Aging Neuroscience, 2021
Neurological deficits after stroke are closely related to white matter microstructure damage. However, secondary changes in white matter microstructure after pontine infarction (PI) in the whole brain remain unclear.

Survival Prediction Analysis in Glioblastoma With Diffusion Kurtosis Imaging

Frontiers in Oncology, 2021
Simple SummaryGlioblastoma (GBM) is the most common and aggressive primary brain tumor. Diffusion kurtosis imaging (DKI) has characterized non-Gaussian diffusion behaviors in brain normal tissue and gliomas, but there are very limited efforts in ...
