Addressing the path-length-dependency confound in white matter tract segmentation.

PLoS ONE, 2014
We derive the Iterative Confidence Enhancement of Tractography (ICE-T) framework to address the problem of path-length dependency (PLD), the streamline dispersivity confound inherent to probabilistic tractography methods.

Directionality of longitudinal associations between frontostriatal structural connectivity and depressive symptoms in adolescent girls

Journal of Child Psychology and Psychiatry, EarlyView.
Background Individual differences in the structure and function of the frontostriatal reward network have been related to depression. However, there is a strong need for prospective, longitudinal studies aiming to understand the role of frontostriatal networks in depression in a developmental context.

Double dissociation between conduction aphasia and conduction agraphia supports a ventro‐dorsal partition of the left arcuate fasciculus

Journal of Neuropsychology, EarlyView.
Abstract We identified in two awake surgery cases a postoperative double dissociation between phonological and graphemic output buffer deficits. Using lesion‐symptom mapping from ischaemic mini‐strokes and preoperative tractography, we demonstrated that the phonological (resp. graphemic) disorder fitted with ventral (resp.

MR Diffusion Tractography

, 2014
In this chapter we describe the underlying principles and most common techniques in diffusion tractography. We cover deterministic streamline tractography and several different probabilistic approaches. We aim to provide a conceptual understanding of the different approaches, but where necessary we introduce mathematical concepts for the more advanced ...

Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth

Journal of Anatomy, EarlyView.
Muscle architecture (physiological cross‐sectional area, fascicle lengths and pennation angle) was measured from multimodal MRI scans of the lower legs of 197 children aged ≤15 years. We showed that lower leg muscle volumes (product of PCSA and fascicle length) increase primarily through increases in PCSA (transverse growth) rather than increases in ...
