Quality assessment of high angular resolution diffusion imaging data using bootstrap on Q-ball reconstruction.
PURPOSE To develop a bootstrap method to assess the quality of High Angular Resolution Diffusion Imaging (HARDI) data using Q-Ball imaging (QBI) reconstruction. MATERIALS AND METHODS HARDI data were re-shuffled using regular bootstrap with jackknife sampling. For each bootstrap dataset, the diffusion orientation distribution function (ODF) was estimated voxel-wise using QBI reconstruction bas...
متن کاملProbabilistic fiber tracking using the residual bootstrap with constrained spherical deconvolution.
Constrained spherical deconvolution (CSD) is a new technique that, based on high-angular resolution diffusion imaging (HARDI) MR data, estimates the orientation of multiple intravoxel fiber populations within regions of complex white matter architecture, thereby overcoming the limitations of the widely used diffusion tensor imaging (DTI) technique. One of its main applications is fiber tractogr...
متن کاملQuantifying the intra- and inter-subject variability of whole-brain structural networks from diffusion MRI
INTRODUCTION Connectomics is a recent development in neuroscience that combines diffusion MRI (dMRI) and tractography with the analytical tools of network theory to investigate whole-brain connectivity [1]. Under this paradigm, segmented cortical areas (e.g. Brodmann areas) form the nodes of a network and tractography is used to construct a set of white matters tracts which form the connections...
متن کاملGenetics of Path Lengths in Brain Connectivity Networks: HARDI-Based Maps in 457 Adults
Brain connectivity analyses are increasingly popular for investigating organization. Many connectivity measures including path lengths are generally defined as the number of nodes traversed to connect a node in a graph to the others. Despite its name, path length is purely topological, and does not take into account the physical length of the connections. The distance of the trajectory may also...
متن کاملNeocortex Organization and Connectivity in Fetal Human Brains Revealed by Diffusion Tractography and Histology
Introduction: During the late fetal period and early preterm period, the most prominent transient layer is the subplate (SP) zone, located between the immature cortex (cortical plate; CP) and the immature white matter (intermediate zone; IZ), which contains awaiting thalamo-cortical afferent fibers that cross one another [1-3]. The SP is especially thick in humans which develops around prenatal...
