Robust constrained weighted least squares for in vivo human cardiac diffusion kurtosis imaging [PDF]

Purpose Cardiac diffusion tensor imaging (cDTI) can investigate the microstructure of heart tissue. At sufficiently high b-values, additional information on microstructure can be observed, but the data require a representation such as diffusion kurtosis

Mean kurtosis-Curve (MK-Curve) correction improves the test–retest reproducibility of diffusion kurtosis imaging at 3 T [PDF]

, 2023
Diffusion kurtosis imaging (DKI) is applied to gain insights into the microstructural organization of brain tissues. However, the reproducibility of DKI outside brain white matter, particularly in combination with advanced estimation to remedy its noise ...

White matter changes in recovered COVID-19 patients: insights from DTI, DKI, and NODDI metrics

Frontiers in Neurology
BackgroundCOVID-19 affects not only the respiratory system but also the central nervous system, resulting in symptoms such as anosmia and confusion. Understanding the long-term neurological effects of COVID-19 is critical for comprehensive patient care ...

High-resolution diffusion kurtosis imaging at 3T enabled by advanced post-processing

Frontiers in Neuroscience, 2015
Diffusion Kurtosis Imaging (DKI) is more sensitive to microstructural differences and can be related to more specific micro-scale metrics (e.g. intra-axonal volume fraction) than diffusion tensor imaging (DTI), offering exceptional potential for clinical

Optimized workflow for diffusion kurtosis imaging of newborns

, 2011
: Diffusional kurtosis imaging (DKI) is a recently proposed extension of the conventional DTI model. It has been shown to offer more sensitive characterization of neural tissues than DTI.

Tracking microstructural adaptations in primary visual areas: A diffusion kurtosis imaging study on visuomotor learning

NeuroImage
This study investigates the potential of Diffusion Kurtosis Imaging (DKI) to detect microstructural changes induced by visuomotor training and its added value over Diffusion Tensor Imaging (DTI).Fourteen healthy participants completed a six-week home ...

Tensor estimation for double-pulsed diffusional kurtosis imaging [PDF]

, 2017
Double-pulsed diffusional kurtosis imaging (DP-DKI) represents the double diffusion encoding (DDE) MRI signal in terms of six-dimensional (6D) diffusion and kurtosis tensors. Here a method for estimating these tensors from experimental data is described.

Multiparametric MRI in primary cerebral lymphoma: Correlation between diffusion kurtosis imaging (DKI), dynamic contrast enhanced (DCE) and dynamic Susceptibility contrast (DSC) MRI techniques

Physica Medica
The aim of our study is to verify the reliability of Diffusion Kurtosis Imaging (DKI) parameters through correlation with perfusion metrics obtained by Dynamic Contrast Enhanced (DCE)- and Dynamic Susceptibility Contrast (DSC)-MRI techniques in histologic-proven primary central nervous system lymphoma (PCNSL).A total of 15 lesions were analyzed in ...
