Fully Automated Plane Prescription in Cardiac MRI: A Prospective Cohort Study

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Accurate plane positioning is important for high‐quality cardiac MRI images but requires specialized training, limiting accessibility. Purpose To evaluate an automated plane positioning tool and compare it with manual planning. Study Type Prospective.

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Cardiac MR Fingerprinting at 0.55T Using a Deep Image Prior for Joint T1, T2, and M0 Mapping

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background 0.55T systems offer unique advantages and may support expanded access to cardiac MRI. Purpose To assess the feasibility of 0.55T cardiac MR Fingerprinting (MRF), leveraging a deep image prior reconstruction to mitigate noise. Study Type Phantom and prospective in vivo assessment.

Analysis of Pulsatile Vessel Expansion in Healthy, COPD‐and PH‐Patients Using Dynamic Vessel Segmentation in Free‐Breathing Lung MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Fetal Ductal Constriction, Pulmonary Hypertension and Atrial Septum Mobility

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives Fetuses with ductal constriction (FDC), pulmonary hypertension and right ventricular overload after maternal exposure to PGE2 inhibitors—nonsteroidal anti‐inflammatory drugs (NSAIDs) or polyphenols (PF)—have increased septum primum excursion index (SPEI), the ratio between maximal septum primum displacement and left atrial diameter.

MiR‐145‐5p Attenuates Doxorubicin‐Induced Heart Injury Through Targeting Cardiomyocyte Pyroptosis

open access: yesThe 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.

Alogliptin Reduces Oxidative Stress in Cardiomyocytes and Ameliorates Diabetic Cardiomyopathy via the AURKB/NLGN2 Signaling

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Diabetic cardiomyopathy (DCM) is a common complication of diabetes mellitus. This study investigated the effects of alogliptin on DCM and its underlying mechanisms. A DCM model was constructed and treated with alogliptin. Downstream targets of alogliptin were screened using bioinformatics analysis.
