Repeatability of Metabolic Imaging With Hyperpolarized Pyruvate: Back‐to‐Back Neuroimaging and Blood Analysis

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 13C MRI with hyperpolarized [1‐13C]pyruvate enables noninvasive imaging of metabolic pathways. Considering the high dose of pyruvate used in hyperpolarized 13C‐pyruvate studies, circulating 13C‐pyruvate and the resulting 13C‐lactate in plasma may influence subsequent pyruvate metabolism, yet the guidance on consecutive injections does ...

VQ‐Wave: A Physics‐Driven Spatiotemporal Deep Learning Approach for Noncontrast‐Enhanced Lung Ventilation and Perfusion MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a robust deep learning framework for noncontrast‐enhanced functional lung MRI, overcoming the limitations of spectral decomposition in the presence of physiological nonstationarity. Methods We introduce VQ‐Wave (Ventilation/Q‐perfusion Waveform‐based Assessment of Variable Evolutions), a physics‐driven spatiotemporal ...

Hemodynamic Modeling and Phase‐Adjustable Reconstruction of Hyperpolarized Cardiac 13C MRS Using 1H Cine and ECG Timing

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To deconvolve cardiac phase and hemodynamic effects in hyperpolarized (HP) [1‐13C]pyruvate and to develop a cardiac phase‐adjustable reconstruction framework. Methods Cardiac phase drift during dynamic acquisition of HP 13C MRS and its effect on dynamic signal fidelity were simulated using a digital cardiac phantom. A hemodynamic model

Ventilation Imaging of the Lung at 0.55T With Continuous Slice Cycling

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose and evaluate a novel method for pulmonary ventilation imaging, offering considerably improved SNR. Methods A continuous slice cycling (CSC) acquisition scheme is proposed to exclusively capture signal modulations from respiratory motion with increased SNR.

Preclinical Toxicity Screening of Sodium Dodecanoyloxybenzenesulfonate (LOBS) as a New Alternative Biocide Using In Vitro and In Vivo Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Sodium hypochlorite is a well‐established biocide extensively used in both living and industrial environments; however, exposure to it or improper handling can harm the human body and the environment. Thus, safer alternatives to sodium hypochlorite are required.

US State Policy Contexts and Mental Health Among Working‐Age Adults

open access: yesThe Milbank Quarterly, EarlyView.
Policy Points States’ overarching policy contexts are a meaningful yet overlooked predictor of adults’ mental health, with more conservative contexts associated with worse mental health outcomes over a 30‐year period. Counterfactual analyses suggest that widespread policy shifts could meaningfully alter the national prevalence of mental distress ...

US State Policy Index for Population Health Analyses

open access: yesThe Milbank Quarterly, EarlyView.
Policy Points Changes in states’ policy contexts since the 1980s may help explain why mortality rates among working‐age adults have risen and become more unequal across geographic areas. Investigating this pressing issue requires a new, industry‐standard measure of those contexts.
