Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background The electrocardiogram (ECG) used for gating in cardiac MRI may be compromised by multiple confounders inside the scanner bore. Purpose To quantify the influence of magnetic field strengths (1.5 T/3 T/7 T), standardized electrode positions, and imaging sequences on ECG signals used for gating. Study Type Prospective.

Quantitative MRI Values for Atrial and Ventricular Parameters in Altitude‐Dwelling Youth
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background The hypoxic environment on the Qinghai Plateau significantly exacerbates myocardial remodeling, with sex/ethnicity‐specific variations in cardiac parameters among local youth. Current cardiac MRI reference values lack data from physiologically adapted populations on this plateau.

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background A detailed evaluation of hemodynamics, supportive morphology, and deformation may help uncover the pathophysiology of hypertrophic obstructive cardiomyopathy (HOCM) and the changes wrought by alcohol septal ablation (ASA). Purpose To investigate the global cardiac volume, myocardial deformation, and hemodynamic characteristics ...

MiR‐145‐5p Attenuates Doxorubicin‐Induced Heart Injury Through Targeting Cardiomyocyte Pyroptosis
The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Doxorubicin (DOX), a potent anthracycline chemotherapeutic, exhibits dose‐dependent cardiotoxicity that limits its clinical utility. Although miR‐145‐5p demonstrates cardioprotective properties in cardiovascular diseases, its role in DOX‐induced cardiomyopathy remains undefined.

Online Spatiotemporally Constrained Reconstruction for Real‐Time Interactive MRI
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To develop a low‐latency dynamic MRI reconstruction that provides better spatial and temporal fidelity than contemporary online reconstruction, for localization. Methods We utilize online spatiotemporally constrained reconstruction (STCR) using a computationally efficient augmented Lagrangian solution and a limited number of iterations
