Evaluation of Third‐Order Motion‐Compensated Cardiac Diffusion Tensor Imaging Across Cardiac Phases Using an Ultra‐High‐Performance Clinical Scanner

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1365-1378, September 2026.
ABSTRACT Purpose To evaluate a third‐order motion‐compensated spin echo (M3‐MCSE) sequence at multiple cardiac phases on a clinical 3 T MRI scanner with ultra‐high performance (UHP) gradients (200 mT/m), compared with stimulated echo acquisition mode (STEAM) and second‐order MCSE (M2‐MCSE) for cardiac diffusion tensor imaging (cDTI).

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

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1054-1065, September 2026.
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

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1206-1218, September 2026.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Quantification of Tricuspid Valve Regurgitation With 2D and 4D‐Flow MRI: Comparison of Different Methods in Adult Patients With Ebstein's Anomaly

Journal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 515-523, August 2026.
ABSTRACT Background Ebstein's anomaly (EA) is a congenital heart disorder involving tricuspid valve dysplasia and right heart abnormalities resulting in severe tricuspid regurgitation (TR). Multiple techniques assess regurgitation severity, but their correlation with EA severity markers remains unclear. Purpose To compare MRI techniques for quantifying

Free‐Breathing 3D Whole Heart and Aorta Cine MRI Without Contrast Agent—Comparison to Clinical Standard

Journal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 524-535, August 2026.
ABSTRACT Background The demand for cardiac MRI is increasing with the growing burden of cardiovascular disease. However, conventional protocols require sequential acquisitions for multi‐breath‐hold 2D cine and 3D MR angiography (MRA), which is time‐consuming.
