Motion‐Robust Approach for 4D Cardiac Cine Using 2D Real‐Time Acquisitions and Slice‐to‐Volume Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 4D cardiac cine is a powerful tool for comprehensive cardiac function assessment; however, current methods rely on regular breathing and are sensitive to bulk motion and arrhythmia. We aim to develop a 4D cardiac cine approach that requires no patient cooperation and is robust to irregular breathing, bulk motion, and cardiac arrhythmia.

Towards Faster Fetal 3D CINE Cardiac MRI Reconstruction Using Region‐Optimized Virtual Coils (ROVir)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate, in a feasibility study, a computationally efficient image‐reconstruction pipeline for 3D balanced steady state free precession (bSSFP) CINE fetal cardiac MRI that reduces radial streaking artifacts, increases effective temporal resolution, and improves diagnostic image quality compared with previous work ...

Strain Rate Angle Distribution as an Indicator of Post‐Infarct Myocardial Remodeling: Proof‐of‐Concept of a Novel Application of the MRI Derived Strain Rate Tensor Field

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Left ventricular (LV) strain is an early indicator of myocardial dysfunction. However, conventional strain metrics do not fully account for the multidirectional nature of myocardial deformation. The strain rate tensor, derived from velocity‐encoded MRI, represents the time‐resolved magnitude and direction of strain rate without the ...

Whole‐Ventricle Cardiac Cine MRI in a Single Breath‐Hold With Slice‐ and Time‐Dependent Deep Image Prior at 0.55T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a whole‐ventricle cardiac cine MRI radial acquisition at 0.55T in a single breath‐hold scan of approximately 12–15 s, reconstructed using a novel self‐supervised slice and time‐dependent deep image prior (ST‐DIP) neural network.

Rotating Frame Spin‐Lock Cardiac MRI Method at 9.4 T Can Characterize Diffuse Fibrosis in Progressing Hypertensive Heart Disease in Mice

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to investigate the applicability of rotating frame spin‐lock continuous wave (CW) T1ρ and relaxation along a fictitious field with Rank 2 (RAFF2) methods complementary to native T1 and late gadolinium enhancement (LGE) for cardiac magnetic resonance imaging (CMRI) of diffuse fibrosis in mice with advancing hypertensive
