Objective QC for diffusion MRI data: artefact detection using normative modelling (2024)
Journal Article
Cirstian, R., Forde, N. J., Andersson, J. L., Sotiropoulos, S. N., Beckmann, C. F., & Marquand, A. F. (2024). Objective QC for diffusion MRI data: artefact detection using normative modelling. Imaging Neuroscience, 2, 1-14. https://doi.org/10.1162/imag_a_00144

Diffusion MRI is a neuroimaging modality used to evaluate brain structure at a microscopic level and can be exploited to map white matter fibre bundles and microstructure in the brain. One common issue is the presence of artefacts, such as acquisitio... Read More about Objective QC for diffusion MRI data: artefact detection using normative modelling.

The spatial extent of anatomical connections within the thalamus varies across the cortical hierarchy in humans and macaques (2024)
Preprint / Working Paper
Howell, A. M., Warrington, S., Fonteneau, C., Cho, Y. T., Sotiropoulos, S. N., Murray, J. D., & Anticevic, A. The spatial extent of anatomical connections within the thalamus varies across the cortical hierarchy in humans and macaques

Each cortical area has a distinct pattern of anatomical connections within the thalamus, a central subcortical structure composed of functionally and structurally distinct nuclei. Previous studies have suggested that certain cortical areas may have m...

Generalising XTRACT tractography protocols across common macaque brain templates (2024)
Journal Article
Assimopoulos, S., Warrington, S., Bryant, K. L., Pszczolkowski, S., Jbabdi, S., Mars, R. B., & Sotiropoulos, S. N. (2024). Generalising XTRACT tractography protocols across common macaque brain templates. Brain Structure and Function, https://doi.org/10.1007/s00429-024-02760-0

Non-human primates are extensively used in neuroscience research as models of the human brain, with the rhesus macaque being a prominent example. We have previously introduced a set of tractography protocols (XTRACT) for reconstructing 42 correspondi...

On the stability of canonical correlation analysis and partial least squares with application to brain-behavior associations (2024)
Journal Article
Helmer, M., Warrington, S., Mohammadi-Nejad, A., Ji, J. L., Howell, A., Rosand, B., …Murray, J. D. (2024). On the stability of canonical correlation analysis and partial least squares with application to brain-behavior associations. Communications Biology, 7(1), Article 217. https://doi.org/10.1038/s42003-024-05869-4

Associations between datasets can be discovered through multivariate methods like Canonical Correlation Analysis (CCA) or Partial Least Squares (PLS). A requisite property for interpretability and generalizability of CCA/PLS associations is stability...

Denoising Diffusion MRI: Considerations and implications for analysis (2023)
Journal Article
Manzano-Patron, J.-P., Moeller, S., Andersson, J. L. R., Ugurbil, K., Yacoub, E., & Sotiropoulos, S. N. (2024). Denoising Diffusion MRI: Considerations and implications for analysis. Imaging Neuroscience, 2, 1-29. https://doi.org/10.1101/2023.07.24.550348

Development of diffusion MRI (dMRI) denoising approaches has experienced considerable growth over the last years. As noise can inherently reduce accuracy and precision in measurements, its effects have been well characterised both in terms of uncerta...

A resource for development and comparison of multimodal brain 3T MRI harmonisation approaches (2023)
Journal Article
Warrington, S., Ntata, A., Mougin, O., Campbell, J., Torchi, A., Craig, M., …Sotiropoulos, S. N. (2023). A resource for development and comparison of multimodal brain 3T MRI harmonisation approaches. Imaging Neuroscience, 1(2023), 1-27. https://doi.org/10.1162/imag_a_00042

Despite the huge potential of magnetic resonance imaging (MRI) in mapping and exploring the brain, MRI measures can often be limited in their consistency, reproducibility and accuracy which subsequently restricts their quantifiability. Nuisance nonbi... Read More about A resource for development and comparison of multimodal brain 3T MRI harmonisation approaches.
