Glioma-Specific Diffusion Signature in Diffusion Kurtosis Imaging [PDF]

Journal of Clinical Medicine, 2021
Purpose: This study aimed to assess the relationship between mean kurtosis (MK) and mean diffusivity (MD) values from whole-brain diffusion kurtosis imaging (DKI) parametric maps in preoperative magnetic resonance (MR) images from 2016 World Health Organization Classification of Tumors of the Central Nervous System integrated glioma groups.

Diffusion Kurtosis Imaging in the Assessment of Cervical Carcinoma

Academic Radiology, 2020
To evaluate the additional value of diffusion kurtosis imaging (DKI) in the characterization of cervical carcinoma.Seventy-five patients (56.9 ± 13.4 years) with histologic-confirmed cervical carcinoma were included. Diffusion-weighted imaging (DWI) was acquired on a 3T MRI with five b values (0, 500, 800, 1000, and 1500 s/mm2).

Fast diffusion kurtosis imaging in acute ischemic stroke shows mean kurtosis‐diffusivity mismatch

Journal of Neuroimaging, 2022
Abstract Background and Purpose Diffusion kurtosis imaging (DKI) is an advanced technique more specific to irreversible ischemic injury than conventional diffusion‐weighted imaging (DWI). However, its clinical translation has been limited by a long acquisition time and complex postprocessing.

MR diffusion kurtosis imaging for neural tissue characterization

NMR in Biomedicine, 2010
AbstractIn conventional diffusion tensor imaging (DTI), water diffusion distribution is described as a 2nd‐order three‐dimensional (3D) diffusivity tensor. It assumes that diffusion occurs in a free and unrestricted environment with a Gaussian distribution of diffusion displacement, and consequently that diffusion weighted (DW) signal decays with ...

Diffusion kurtosis imaging in diffuse axonal injury

Voprosy neirokhirurgii imeni N.N. Burdenko, 2019
Diffuse axonal injury (DAI) is one of the most severe traumatic brain injuries. The availability of neuroimaging biomarkers for monitoring expansion of traumatic brain injury in vivo is a topical issue.To evaluate novel neuroimaging biomarkers for monitoring brain injury using diffusion kurtosis imaging (DKI) in patients with severe diffuse axonal ...

Optimal Experimental Design for Diffusion Kurtosis Imaging

IEEE Transactions on Medical Imaging, 2010
Diffusion kurtosis imaging (DKI) is a new magnetic resonance imaging (MRI) model that describes the non-Gaussian diffusion behavior in tissues. It has recently been shown that DKI parameters, such as the radial or axial kurtosis, are more sensitive to brain physiology changes than the well-known diffusion tensor imaging (DTI) parameters in several ...
