The aims of this study were to implement voxel-based optimization diffusion kurtosis imaging (DKI) and evaluate the accuracy of the method for the analysis of diffusion imaging data in comparison with conventional DKI. Conventional DKI and voxel-based optimization DKI were tested on a phantom and a human in a 1.5 T whole-body scanner.

NMR in Biomedicine
ABSTRACTTraumatic brain injury (TBI) is a major public health concern, but no reliable markers of injury are available. Axonal and microvascular changes are common after TBI, and diffusion MRI offers sensitivity to both. Diffusion kurtosis imaging (DKI) probes tissue microstructure, while intravoxel incoherent motion (IVIM) reflects microvascular flows.

Effects of perfusion on DTI and DKI estimates in the skeletal muscle
Magnetic Resonance in Medicine, 2016PurposeIn this study, we evaluated the effects of perfusion of the skeletal muscle on diffusion tensor imaging (DTI) and diffusional kurtosis imaging (DKI) parameters and their reproducibility.MethodsDiffusion tensor imaging and DKI models, with and without intravoxel incoherent motion (IVIM) correction, were applied to simulated data at different ...
