Functional quantitative susceptibility mapping (fQSM)
Published 2014“…Here, we additionally interrogated the phase data of the fMRI time-series and used quantitative susceptibility mapping (QSM) in order to investigate the potential of functional QSM (fQSM) relative to standard magnitude BOLD fMRI. …”

Investigating the effects of microstructure and magnetic susceptibility in MRI
Published 2016“…In initial work, the use of phase imaging and quantitative susceptibility mapping (QSM) is compared in the analysis of white matter lesions in multiple sclerosis, demonstrating in vivo the dipolar distortions inherent in phase images, and the correction of such artefacts through the application of QSM, based on a thresholded k-space division method . …”

Investigating the magnetic properties of tissue with MRI phase at 7T
Published 2017“…Extending beyond the well established field of quantitative susceptibility mapping (QSM), consideration is given to the influence of susceptibility anisotropy, chemical exchange, non-spherical susceptibility inclusions and multi-compartmental signal evolution from both a theoretical and experimental viewpoint. …”

Applications of susceptibility-based brain imaging using 7T MRI
Published 2019“…These effects were measured using a range of imaging techniques, including susceptibility weighted imaging (SWI) and quantitative susceptibility mapping (QSM). Initially, simulations of static and defusing spins were performed to gain an understanding of the behaviour of different systems, which agreed well with comparison to the results from analytical models. …”

Using MRI to investigate the effect of brain iron in neurodegerative disease
Published 2020“…Three patients who suffer from Alzheimer’s disease (AD) were scanned on a Philips 7T Achieva MRI scanner and a T2* and GRE scan was carried out using a Nova 2Tx/32Rx coil with TE=20 ms. Quantitative susceptibility maps were created from the resulting data in order to look at the feasibility of measuring the susceptibility in the hippocampus in AD patients in a larger study.…”
