Evaluation of non-local means based denoising filters for diffusion kurtosis imaging using a new phantom. [PDF]

PLoS ONE, 2015
Image denoising has a profound impact on the precision of estimated parameters in diffusion kurtosis imaging (DKI). This work first proposes an approach to constructing a DKI phantom that can be used to evaluate the performance of denoising algorithms in

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 ...

Diffusion MRI of the Body: Beyond PGSE‐EPI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Diffusion magnetic resonance imaging (dMRI) is a widely used clinical imaging technique which is sensitive to changes in tissue microstructure including cellularity, perfusion, and tissue damage. DMRI has been used in whole‐body imaging as well as in targeted imaging of every major anatomical region.

Relationship Between Mean Kärger Model Water Exchange Rate and Intercellular Water Transition Rate

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To derive a quantitative relationship between the mean Kärger model (KM) water exchange rate and the mean intercellular water transition rate applicable to brain and other complex biological tissues. Theory and Methods The mean KM water exchange rate applies to any KM, accommodates an arbitrary number of compartments, and can be ...

A Comprehensive Evaluation of Quantitative Diffusion Parameters for Differentiating Histopathological Features and Subtypes of Breast Cancers: Diffusion Kurtosis Imaging (DKI), Intravoxel Incoherent Motion (IVIM) and Histogram Analysis of ADC

, 2023
Abstract Background The objective of this study is to quantitatively compare the diagnostic value of conventional diffusion-weighted imaging (DWI), intravoxel incoherent motion (IVIM), and diffusion kurtosis imaging (DKI) in differentiating the histopathological features and subtypes of breast cancer.
