Purpose: To evaluate accelerated T- and T-mapping techniques for ultra-low-field MRI using low-rank reconstruction methods.

Methods: Two low-rank-based algorithms, image-based locally low-rank (LLR) and k-space-based structured low-rank (SLR), were implemented to accelerate T and T mapping on a 46 mT Halbach MRI scanner. Data were acquired with 3D turbo spin-echo sequences using variable-density poisson-disk random sampling patterns.

Background: Bowel cancer screening in England is initially carried out using a home testing kit, with those who require further testing first being referred to an assessment clinic. During COVID-19, these assessment clinics became 'virtual' (telephone or video-call) where previously they had only been held face-to-face.

Methodology: A before and after study design was constructed to examine the impact of this change in clinic type on key programme metrics.

Purpose: To develop a low-cost, high-performance, versatile, open-source console for low-field MRI applications that can integrate a multitude of different auxiliary sensors.

Methods: A new MR console was realized with four transmission and eight reception channels. The interface cards for signal transmission and reception are installed in PCI Express slots, allowing console integration in a commercial PC rack.

Acute ischemic stroke with large vessel occlusion (LVO) continues to present a considerable challenge to global health, marked by substantial morbidity and mortality rates. Although definitive diagnostic markers exist in the form of neuroimaging, their expense, limited availability, and potential for diagnostic delay can often result in missed opportunities for life-saving interventions. Despite several past attempts, research efforts to date have been fraught with challenges likely due to multiple factors, such as the inclusion of diverse stroke types, variable onset intervals, differing pathobiologies, and a range of infarct sizes, all contributing to inconsistent circulating biomarker levels.

This paper aimed to reflect on how Rigney's model of Indigenist research informed the research design of a project which explored community-led solutions to improve food security in remote Aboriginal and Torres Strait Islander communities. The project was conducted in partnership with two Aboriginal Community Controlled Health Organisations (ACCHOs); Apunipima Cape York Health Council (Apunipima) and Central Australian Aboriginal Congress (Congress), communities in Central Australia and Cape York, Queensland and researchers from the University of Queensland, Monash University, Dalhousie University and Menzies School of Health Research. On reflection the principles of Indigenist research were evident providing a means of resistance to oppression through Indigenous stakeholders being in control of research to address social determinants, in this case food security.
