Comparison of Diffusion Kurtosis Imaging and Standard Mono-Exponential Apparent Diffusion Coefficient in Diagnosis of Significant Prostate Cancer—A Correlation with Gleason Score Assessed on Whole-Mount Histopathology Specimens

Diagnostics, 2023
Background: The study was undertaken to compare the diagnostic performance of diffusion kurtosis imaging (DKI) with the standard monoexponential (ME) apparent diffusion coefficient (ADC) model in the detection of significant prostate cancer (PCa), using ...

Histological correlation of diffusional kurtosis and white matter modeling metrics in cuprizone-induced corpus callosum demyelination [PDF]

, 2014
The cuprizone mouse model is well established for studying the processes of both demyelination and remyelination in the corpus callosum, and it has been utilized together with diffusion tensor imaging (DTI) to investigate myelin and axonal pathology ...

Erweiterte Anwendung der Diffusions-Kurtosis-Bildgebung

, 2020
Die Diffusions-Tensor-Bildgebung (DTI) zur Rekonstruktion und Visualisierung von Fasertrakten im Gehirn zählt mittlerweile zu den Standardverfahren in der klinischen Routine und der neurowissenschaftlichen Forschung. Aufgrund der vereinfachenden Annahme des zugrundliegenden Tensormodells - einer Gaußschen Verteilung der Diffusion - ist eine räumlich ...

Diffusion Kurtosis Imaging of Neonatal Spinal Cord in Clinical Routine [PDF]

Frontiers in Radiology, 2021
Diffusion kurtosis imaging (DKI) has undisputed advantages over the more classical diffusion magnetic resonance imaging (dMRI) as witnessed by the fast-increasing number of clinical applications and software packages widely adopted in brain imaging. However, in the neonatal setting, DKI is still largely underutilized, in particular in spinal cord (SC ...

Diffusion tensor model links to neurite orientation dispersion and density imaging at high b-value in cerebral cortical gray matter [PDF]

, 2019
Diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) are widely used models to infer microstructural features in the brain from diffusion-weighted MRI. Several studies have recently applied both models to increase

Diffusion kurtosis imaging as a biomarker of breast cancer

BJR|Open, 2023
Diffusion kurtosis imaging (DKI) is a diffusion-weighted imaging method that describes non-Gaussian signal behavior using a relatively simple mathematical model. A parameter, kurtosis K, describes the deviation of the diffusion signal decay from a Gaussian pattern.

Positive definiteness of Diffusion Kurtosis Imaging

Inverse Problems & Imaging, 2012
Diffusion Kurtosis Imaging (DKI) is a new Magnetic Resonance Imaging (MRI) model to characterize the non-Gaussian diffusion behavior in tissues. In reality, the term $bD_{app}-\frac{1}{6}b^2D_{app}^2K_{app}$ in the extended Stejskal and Tanner equation of DKI should be positive for an appropriate range of $b$-values to make sense physically.

Dynamic changes in hippocampal diffusion and kurtosis metrics following experimental mTBI correlate with glial reactivity

NeuroImage: Clinical, 2019
Diffusion magnetic resonance imaging biomarkers can provide quantifiable information of the brain tissue after a mild traumatic brain injury (mTBI). However, the commonly applied diffusion tensor imaging (DTI) model is not very specific to changes in the
