Time course of axial and radial diffusion kurtosis of white matter infarctions: period of pseudonormalization.
BACKGROUND AND PURPOSE Diffusion kurtosis is a statistical measure for quantifying the deviation of the water diffusion profile from a Gaussian distribution. The current study evaluated the time course of diffusion kurtosis in patients with cerebral infarctions, including perforator, white matter, cortical, and watershed infarctions. MATERIALS AND METHODS Subjects were 31 patients, representi...
متن کاملRecent Developments in Fast Kurtosis Imaging
Diffusion kurtosis imaging (DKI) is an extension of the popular diffusion tensor imaging (DTI) technique. DKI takes into account leading deviations from Gaussian diffusion stemming from a number of effects related to the microarchitecture and compartmentalization in biological tissues. DKI therefore offers increased sensitivity to subtle microstructural alterations over conventional diffusion i...
متن کاملStratification of heterogeneous diffusion MRI ischemic lesion with kurtosis imaging: evaluation of mean diffusion and kurtosis MRI mismatch in an animal model of transient focal ischemia.
BACKGROUND AND PURPOSE Ischemic tissue damage is heterogeneous, resulting in complex patterns in the widely used diffusion-weighted MRI. Our study examined the spatiotemporal characteristics of diffusion kurtosis imaging in an animal model of transient middle cerebral artery occlusion. METHODS Adult male Wistar rats (N=18) were subjected to 90 minutes middle cerebral artery occlusion. Multipa...
متن کاملDiffusion Kurtosis Imaging in Prostate Cancer
Introduction: Diffusion weighted imaging (DWI) and the calculated apparent diffusion coefficient (ADC) is showing potential for improving detection of prostate cancer (PCa), as the increased cellularity of many tumors is associated with restricted water diffusion and thus with a decreased ADC [1,2]. The ADC assumes Gaussian water diffusion and is calculated by monoexponential fitting. However, ...
متن کاملEvaluation of cerebral glioma using 3T diffusion kurtosis tensor imaging and the relationship between diffusion kurtosis metrics and tumor cellularity
Purpose To evaluate the clinical utility of diffusion kurtosis tensor imaging in the characterization of cerebral glioma and investigate correlations between diffusion and kurtosis metrics with tumor cellularity. Materials and Methods A group of 163 patients (age: 40.5 ± 11.5 years) diagnosed with cerebral glioma underwent diffusion kurtosis tensor imaging with a 3 T scanner. Diffusion and kurt...
