Advanced Methods for Diffusion MRI Data Analysis and their Application to the Healthy Ageing Brain
… orientation dispersion and density imaging (NODDI), it is shown that spherical deconvolution techniques can be used to characterize fibre crossing and dispersion simultaneously. Fourthly, free water volume fraction estimates provided by the free water diffusion tensor imaging (fwDTI) are …

From Structure to Function: Social and Cognitive Networks in Children Born Very Low Birth Weight
… (NDI) were estimated using diffusion tensor and NODDI models. Using magnetoencephalography, social and cognitive networks were assessed during a resting-state (Study 3) and an emotional face processing task (Study 4). Studies 1 & 2 demonstrated disrupted white matter maturation in VLBW compared …

Synaptic loss in the primary tauopathies of Progressive Supranuclear Palsy and Corticobasal Degeneration
… the Neurite Orientation and Dispersion Index, NODDI). In accordance with in vitro and animal models, I confirm that loss of dendritic complexity is tightly coupled with presynaptic density, over and above the effects of atrophy. In chapter five, I test the relationship between the molecular …

DTI-ALPS REFLECTS WHITE MATTER DIFFUSION ANISOTROPY AND MICROSTRUCTURAL HETEROGENEITY RATHER THAN GLYMPHATIC FLOW: INSIGHTS FROM MULTI-MODAL MRI
… and neurite orientation and density imaging (NODDI) metrics, including the orientation dispersion index (ODI), neurite density index (NDI), and isotropic volume fraction (FISO). We also computed the T1/FLAIR signal ratio and the diamagnetic component of susceptibility (DCS) derived from …
