Low-field magnetic resonance imaging (MRI) gains renewed attention as advances in hardware and software narrow the performance gap with high-field systems. Historically sidelined for lower signal-to-noise ratio and reduced spatial resolution, low-field platforms now integrate optimised magnet designs, improved radiofrequency coils and AI-enabled...Read more

Neuroimaging can summarise how a brain compares with typical ageing by estimating a brain age and contrasting it with a person’s actual age. The difference, known as the brain age gap (BAG), indicates whether a brain appears older or younger than expected on a given scan type. BAGs drawn from structural, molecular, functional and diffusion imaging...Read more

Diffusion-weighted imaging (DWI) probes tissue microstructure by capturing water motion and translating it into contrast that supports detection, characterisation and treatment assessment across brain and body. Diagnostic value depends on coherent protocol choices, control of artefacts and disciplined interpretation with the apparent diffusion...Read more

Vascular cognitive impairment (VCI) is the second most prevalent form of dementia, presenting significant challenges for diagnosis and management. VCI encompasses a continuum from subjective cognitive decline to full-blown dementia, primarily caused by cerebrovascular damage. With projections estimating 1.5 billion individuals over 65 by 2050,...Read more

Advancements in cancer treatment, particularly with immunotherapy and targeted agents, have significantly improved outcomes across a range of malignancies. However, these therapies bring with them a spectrum of neurotoxic complications that challenge timely recognition and management. Traditional treatments such as chemotherapy and radiotherapy...Read more

Accurate and timely imaging is central to the evaluation of memory loss, particularly in conditions such as Alzheimer’s disease and other neurodegenerative disorders. The magnetisation-prepared rapid gradient echo (MPRAGE) sequence, a standard T1-weighted three-dimensional MRI technique, has long been a clinical mainstay for visualising cerebral...Read more

Acute ischemic stroke (AIS) remains a major cause of death and long-term disability. Timely imaging and accurate analysis of brain lesions are critical to predicting functional recovery and guiding clinical decision-making. Traditionally, infarct size has served as a principal radiologic marker, but it offers only moderate predictive power, especially...Read more

Parkinson’s disease (PD) is the second most prevalent neurodegenerative disorder worldwide, yet early diagnosis remains a significant challenge. Standard clinical assessments and conventional MRI lack specificity, leading to notable misclassification rates, especially in early disease stages. While advanced imaging modalities can improve diagnostic...Read more
