Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Multiscale mechanistic modelling of heterogeneity in cardiac sub‐cellular calcium handling accounting for variable t‐system density

The Journal of Physiology, EarlyView.
Abstract figure legend Illustration of spatial calcium dynamics (left panels) and the state cycle approximation (middle panel) that enables reduced simulation of spatially dependent dynamics without explicit description of space (right panels). The selected example here illustrates a spontaneous calcium wave, showing temporal snapshots of local calcium

Human In Vivo Validation of Frequency‐Dependent QTI

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2642-2659, December 2026.
ABSTRACT Purpose The aim of this work is to investigate if q‐space trajectory imaging (QTI) waveforms can be designed to probe QTI metrics at a single centroid frequency under realistic experimental conditions for in vivo human brain imaging. Methods Realistic diffusion encoding waveforms based on double‐rotation gradient waveform and magic‐angle ...

Evaluation of 7 Tesla pTx Body Coils Regarding Transmit and Receive Performance

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2988-3001, December 2026.
ABSTRACT Purpose Most sites develop and use custom coils for 7 T body MRI since no standard pTx body coil exists, leading to diverse coil designs differing in transmit element type, layout, and number of receive channels. This study investigates and compares eight existing coils, including one remote body coil array and seven local arrays, regarding ...
