Automatic Respiratory and Bulk Patient Motion Corrected 3D Fetal MRI

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1972-1985, April 2026.
ABSTRACT Purpose To develop a framework (ACROBATIC) for correcting motion in 3D radial fetal MRI. Methods Data were simulated (N = 200) and acquired in utero (N = 11, gestational age: 32 ± 2 weeks). Motion due to maternal respiration was estimated by extracting a self‐gating signal and applying focused navigation. Bulk motion was estimated by splitting

Feasibility Study for Dual Phase Free Breathing 3D bSSFP MRA With Preserved Eddy‐Current Tolerance With Adaptive k‐Space Lengths (PETAL) Acquisition

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2078-2091, April 2026.
ABSTRACT Purpose To demonstrate the feasibility of a novel dual‐phase self‐navigated, free‐breathing balanced steady‐state free‐precession whole‐heart MRA acquisition for aortic annulus size measurement using a Cartesian trajectory that mitigates eddy‐current artifacts by minimizing k‐space jumps between consecutive readouts with predictable scan times.

Free‐Breathing, 3D Cardiac Magnetic Resonance Elastography for Myocardial Stiffness Mapping

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2356-2369, April 2026.
ABSTRACT Purpose Magnetic resonance elastography (MRE) of the heart has predominantly utilized breath‐held acquisitions with limited anatomic coverage. This work investigates the feasibility of 3D, free‐breathing cardiac MRE. Methods A 3D hybrid radial and EPI acquisition is utilized and combined with retrospective binning of k‐space via physiologic ...

From Fiber Architecture to Functional Attachment: A Clinically Relevant, Mechanically Tunable Cardiac Patch

Advanced Materials, Volume 38, Issue 17, 20 March 2026.
A personalizable platform featuring a multi‐zonal cardiac patch design at clinical scale enables precise customization of fiber architecture at micro‐ and macroscale via melt electrowriting. Distinct scaffold zones support cell alignment with mechanical force transfer and epicardial attachment.

Unusual Synchronous Arbitrary‐Gate Doppler Spectra Enable Intraoperative Hemodynamic Warning of Cerebral Hyperperfusion Syndrome on Moyamoya Disease

CNS Neuroscience &Therapeutics, Volume 32, Issue 3, March 2026.
Synchronous arbitrary‐gate spectral Doppler (SAGSD) enables real‐time multi‐site hemodynamic monitoring during moyamoya disease revascularization. The novel “mountain” sign, defined as three or more velocity peaks within one cardiac cycle across multiple subcortical sites, was detected in 5 of 6 patients who developed cerebral hyperperfusion syndrome ...

Quantitative MRI Values for Atrial and Ventricular Parameters in Altitude‐Dwelling Youth

Journal of Magnetic Resonance Imaging, Volume 63, Issue 3, Page 828-845, March 2026.
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.

Alcohol Septal Ablation in Hypertrophic Obstructive Cardiomyopathy: Long‐Term Follow‐Up of Deformations and Hemodynamics

Journal of Magnetic Resonance Imaging, Volume 63, Issue 3, Page 859-871, March 2026.
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 ...
