Deuterium brain imaging at 7T during D2O dosing (2022)
Journal Article

Purpose To characterize the (2H) deuterium MR signal measured from human brain at 7T in participants loading with D2O to ˜1.5% enrichment over a six-week period. Methods 2H spectroscopy and imaging measurements were used to track the time-course... Read More about Deuterium brain imaging at 7T during D2O dosing.

Improved Dynamic Contrast-Enhanced MRI Using Low Rank with Joint Sparsity (2022)
Journal Article

This work presents a free-breathing dynamic contrast-enhanced (DCE) MRI reconstruction method called low-rank plus sparse (L+S) with joint sparsity. The proposed method improved dynamic contrast performance by integrating an additional temporal Fast... Read More about Improved Dynamic Contrast-Enhanced MRI Using Low Rank with Joint Sparsity.

Chronic neuropsychiatric sequelae of SARS-CoV-2: Protocol and methods from the Alzheimer's Association Global Consortium (2022)
Journal Article

Introduction: Coronavirus disease 2019 (COVID-19) has caused >3.5 million deaths worldwide and affected >160 million people. At least twice as many have been infected but remained asymptomatic or minimally symptomatic. COVID-19 includes central nervo...

A lightweight magnetically shielded room with active shielding (2022)
Journal Article

Magnetically shielded rooms (MSRs) use multiple layers of materials such as MuMetal to screen external magnetic fields that would otherwise interfere with high precision magnetic field measurements such as magnetoencephalography (MEG). Optically pump... Read More about A lightweight magnetically shielded room with active shielding.

Bespoke magnetic field design for a magnetically shielded cold atom interferometer (2022)
Journal Article

Quantum sensors based on cold atoms are being developed which produce measurements of unprecedented accuracy. Due to shifts in atomic energy levels, quantum sensors often have stringent requirements on their internal magnetic field environment. Typic...

Phenotypic and genetic associations of quantitative magnetic susceptibility in UK Biobank brain imaging (2022)
Journal Article

A key aim in epidemiological neuroscience is identification of markers to assess brain health and monitor therapeutic interventions. Quantitative susceptibility mapping (QSM) is an emerging magnetic resonance imaging technique that measures tissue ma...

Magnetic field design in a cylindrical high-permeability shield: The combination of simple building blocks and a genetic algorithm (2022)
Journal Article

Magnetically sensitive experiments and newly developed quantum technologies with integrated high-permeability magnetic shields require increasing control of their magnetic field environment and reductions in size, weight, power, and cost. However, ma... Read More about Magnetic field design in a cylindrical high-permeability shield: The combination of simple building blocks and a genetic algorithm.

Triaxial detection of the neuromagnetic field using optically-pumped magnetometry: feasibility and application in children (2022)
Journal Article

Optically-pumped magnetometers (OPMs) are an established alternative to superconducting sensors for magnetoencephalography (MEG), offering significant advantages including flexibility to accommodate any head size, uniform coverage, free movement duri...
