Diffusional Kurtosis Imaging in the Diffusion Imaging in Python Project [PDF]

Frontiers in Human Neuroscience, 2021
Diffusion-weighted magnetic resonance imaging (dMRI) measurements and models provide information about brain connectivity and are sensitive to the physical properties of tissue microstructure.

Survival Prediction Analysis in Glioblastoma With Diffusion Kurtosis Imaging [PDF]

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 ...

Diffusion weighted imaging and diffusion kurtosis imaging in abdominal oncological setting: why and when

Infectious Agents and Cancer, 2022
This article provides an overview of diffusion kurtosis (DKI) imaging in abdominal oncology. DKI allows for more data on tissue structures than the conventional diffusion model (DWI).

Diffusion Kurtosis Imaging [PDF]

, 2020
Diffusion Kurtosis Imaging (DKI) is an advanced imaging technique that expands the utility of diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI). Kurtosis is a measure of skewness of the shape of a probability distribution, which reflects the deviation of a given distribution from the normal Gaussian distribution.

Toward more robust and reproducible diffusion kurtosis imaging [PDF]

Magnetic Resonance in Medicine, 2021
AbstractPurposeThe general utility of diffusion kurtosis imaging (DKI) is challenged by its poor robustness to imaging artifacts and thermal noise that often lead to implausible kurtosis values.Theory and MethodsA robust scalar kurtosis index can be estimated from powder‐averaged diffusion‐weighted data.

Quantitative measurement of diffusion-weighted imaging signal using expression-controlled aquaporin-4 cells: Comparative study of 2-compartment and diffusion kurtosis imaging models.

PLoS ONE, 2022
The purpose of this study was to compare parameter estimates for the 2-compartment and diffusion kurtosis imaging models obtained from diffusion-weighted imaging (DWI) of aquaporin-4 (AQP4) expression-controlled cells, and to look for biomarkers that ...

Correlation Tensor MRI deciphers underlying kurtosis sources in stroke

NeuroImage, 2022
Noninvasively detecting and characterizing modulations in cellular scale micro-architecture remains a desideratum for contemporary neuroimaging. Diffusion MRI (dMRI) has become the mainstay methodology for probing microstructure, and, in ischemia, its ...

In vivo Correlation Tensor MRI reveals microscopic kurtosis in the human brain on a clinical 3T scanner

NeuroImage, 2022
Diffusion MRI (dMRI) has become one of the most important imaging modalities for noninvasively probing tissue microstructure. Diffusional Kurtosis MRI (DKI) quantifies the degree of non-Gaussian diffusion, which in turn has been shown to increase ...
