A standardized MRI phantom for dissolved phase 129Xe MRI (2024)
Journal Article
Filkins, M., Harrison, A., Collier, G. J., Norquay, G., Wild, J. M., Rigby, S. P., Pavlovskaya, G. E., & Meersmann, T. (2024). A standardized MRI phantom for dissolved phase 129Xe MRI. Journal of Magnetic Resonance, 21, Article 100175. https://doi.org/10.1016/j.jmro.2024.100175

Pulmonary MRI of hyperpolarized xenon-129 (hp129Xe) dissolved in the lung parenchyma and vascular phase is gaining increasing attention for clinical assessment of gas exchange in multiple diseases. These conditions can involve thickening of barrier t... Read More about A standardized MRI phantom for dissolved phase 129Xe MRI.

Structural and chemical heterogeneity in ancient glass probed using gas overcondensation, X-ray tomography, and solid-state NMR (2020)
Journal Article
Rigby, S. P., Stevens, L., Meersmann, T., Pavlovskaya, G. E., Rees, G. J., Henderson, J., Bryant, S. J., Edler, K. J., & Fletcher, R. S. (2020). Structural and chemical heterogeneity in ancient glass probed using gas overcondensation, X-ray tomography, and solid-state NMR. Materials Characterization, 167, Article 110467. https://doi.org/10.1016/j.matchar.2020.110467

Rare ancient glasses have complex, multi-scale structures requiring more sophisticated and non-destructive pore characterisation techniques than usual. Homotattic patch models for nitrogen adsorption gave better fits to the isotherm data, more accura...

Fluid flow in a porous medium with transverse permeability discontinuity (2018)
Journal Article
Pavlovskaya, G. E., Meersmann, T., Jin, C., & Rigby, S. P. (2018). Fluid flow in a porous medium with transverse permeability discontinuity. Physical Review Fluids, 3(4), https://doi.org/10.1103/PhysRevFluids.3.044102

Magnetic Resonance Imaging (MRI) velocimetry methods were used to study fully developed axially symmetric fluid flow in a model porous medium of cylindrical symmetry with a transverse permeability discontinuity. Spatial mapping of fluid ow resulted i... Read More about Fluid flow in a porous medium with transverse permeability discontinuity.

Hyperpolarized (hp) 83Kr is a promising MRI contrast agent for the diagnosis of pulmonary diseases affecting the surface of the respiratory zone. However, the distinct physical properties of 83Kr that enable unique MRI contrast also complicate the pr...
