Image processing and Quality Control for the first 10,000 brain imaging datasets from UK Biobank (2017)
Journal Article

UK Biobank is a large-scale prospective epidemiological study with all data accessible to researchers worldwide. It is currently in the process of bringing back 100,000 of the original participants for brain, heart and body MRI, carotid ultrasound an...

The heritability of multi-modal connectivity in human brain activity (2017)
Journal Article

Patterns of intrinsic human brain activity exhibit a profile of functional connectivity that is associated with behaviour and cognitive performance, and deteriorates with disease. This paper investigates the relative importance of genetic factors and... Read More about The heritability of multi-modal connectivity in human brain activity.

Subthalamic deep brain stimulation sweet spots and hyperdirect cortical connectivity in Parkinson’s disease (2017)
Journal Article

Objectives Firstly, to identify subthalamic region stimulation clusters that predict maximum improvement in rigidity, bradykinesia and tremor, or emergence of side-effects; and secondly, to map-out the cortical fingerprint, mediated by the hyperdire...

Estimation of white matter fiber parameters from compressed multiresolution diffusion MRI using sparse Bayesian learning (2017)
Journal Article

We present a sparse Bayesian unmixing algorithm BusineX: Bayesian Unmixing for Sparse Inference-based Estimation of Fiber Crossings (X), for estimation of white matter fiber parameters from compressed (under-sampled) diffusion MRI (dMRI) data. Busine... Read More about Estimation of white matter fiber parameters from compressed multiresolution diffusion MRI using sparse Bayesian learning.

Improved tractography using asymmetric fibre orientation distributions (2017)
Journal Article

Diffusion MRI allows us to make inferences on the structural organisation of the brain by mapping water diffusion to white matter microstructure. However, such a mapping is generally ill-defined; for instance, diffusion measurements are antipodally s... Read More about Improved tractography using asymmetric fibre orientation distributions.

Building connectomes using diffusion MRI: why, how and but (2017)
Journal Article

Why has diffusion MRI become a principal modality for mapping connectomes in vivo? How do different image acquisition parameters, fiber tracking algorithms and other methodological choices affect connectome estimation? What are the main factors that...

Evaluating fibre orientation dispersion in white matter: comparison of diffusion MRI, histology and polarized light imaging (2017)
Journal Article

Diffusion MRI is an exquisitely sensitive probe of tissue microstructure, and is currently the only non-invasive measure of the brain’s fibre architecture. As this technique becomes more sophisticated and microstructurally informative, there is incre...

Time-efficient and flexible design of optimized multishell HARDI diffusion (2017)
Journal Article

Purpose: Advanced diffusion magnetic resonance imaging benefits from collecting as much data as is feasible but is highly sensitive to subject motion and the risk of data loss increases with longer acquisition times. Our purpose was to create a maxim... Read More about Time-efficient and flexible design of optimized multishell HARDI diffusion.

Image quality transfer and applications in diffusion MRI (2017)
Journal Article

This paper introduces a new computational imaging technique called image quality transfer (IQT). IQT uses machine learning to transfer the rich information available from one-off experimental medical imaging devices to the abundant but lower-quality...

Studying neuroanatomy using MRI (2017)
Journal Article

The study of neuroanatomy using imaging enables key insights into how our brains function, are shaped by genes and environment, and change with development, aging, and disease. Developments in MRI acquisition, image processing, and data modelling hav... Read More about Studying neuroanatomy using MRI.
