Geometric water exchange in dendritic spines imparts a similar signature on diffusion‐MRI signals as permeative, transmembrane water exchange. Current diffusion MRI methods are non‐specific to geometric and permeative exchange. This work proposes a method to disentangle these two modes of exchange, yielding both more accurate estimates of permeative ...

ABSTRACT Intravoxel incoherent motion (IVIM) MRI allows for simultaneous assessment of tissue microcirculation (perfusion) and diffusion of water. In single‐center studies, IVIM has shown great potential for diagnosis, treatment outcome prediction, and treatment monitoring for many different diseases and organs.

MRI for Lung Cancer Management: Any Closer to Clinical Application?
ABSTRACT Management of lung cancer (LC) encompasses screening, diagnosis, staging, radiotherapy planning and guidance, therapy monitoring and surveillance. Across these domains, magnetic resonance imaging (MRI) offers a range of morphological and functional imaging capabilities—including diffusion‐weighted imaging (DWI), dynamic contrast‐enhanced (DCE)

ABSTRACT Purpose Oscillating‐gradient spin‐echo (OGSE) diffusion MRI probes cell geometry and membrane integrity through the frequency‐dependence of kurtosis, but prior studies have reported inconsistent findings depending on how frequency is varied. We compared frequency‐dependent kurtosis in the human brain under two regimes: varying frequency with ...

Constrained diffusion kurtosis imaging using ternary quartics & MLE
International audiencePurpose: Diffusion kurtosis imaging (DKI) is a recent improvement over diffusion tensor imaging that characterizes tissue by quantifying non-gaussian diffusion using a 3D fourth-order kurtosis tensor.

Diffusion kurtosis imaging for characterizing tumor heterogeneity in an intracranial rat glioblastoma model [PDF]
The utility of diffusion kurtosis imaging (DKI) for assessing intra-tumor heterogeneity was evaluated in a rat model of glioblastoma multiforme. Longitudinal MRI including T2-weighted and diffusion-weighted MRI (DWI) was performed on six female Fischer ...
