Timing Is Everything: How Subtle Timing Changes in MRI Echo Planar Imaging Can Significantly Alter Mechanical Vibrations and Sound Level

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3116-3130, June 2026.
ABSTRACT Purpose Echo‐Planar Imaging (EPI) is central to fMRI, diffusion MRI, and many dynamic clinical applications, yet rapid gradient switching induces strong mechanical vibrations, generates acoustic noise, and contributes to ghosting artifacts—effects that intensify at ultra‐high fields.

Echo‐Planar‐Based Time‐of‐Flight Imaging Using a Modified Interleaved Flyback Trajectory

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3131-3144, June 2026.
ABSTRACT Purpose A modified interleaved flyback (miFB) approach is introduced, designed to mitigate flow artifacts caused by alternating readout polarities in Echo Planar Imaging (EPI), while preserving acquisition efficiency. Methods We propose reconstructing odd and even echoes of 3D‐EPI separately.

Spatiotemporal Encoding With Nonlinear Gradient Hardware Using Pulseq: From Principles to Practical Demonstration

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3187-3198, June 2026.
Purpose Provide the theoretical foundation and the first practical demonstration of spatiotemporal encoding (SPEN) using additional nonlinear gradient hardware. Methods The quadratic phase profile can be generated either by a chirped‐RF pulse combined with a constant gradient or, directly, by a quadratic gradient pulse.

Toward Super‐Resolution Reconstruction of Diffusion–Relaxation MRI Using Slice Excitation With Random Overlap (SERO)

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3213-3226, June 2026.
ABSTRACT Purpose Diffusion MRI probes tissue microstructure, but low SNR and limited resolution hinder detection of features and parameter estimates. We introduce slice excitation with random overlap (SERO), which enables variable repetition times (TRs) and diffusion weighting within a single shot.

Postexercise Lactate Clearance, T2 Relaxation, and J‐Modulation in Human Skeletal Muscle Measured With Double‐Quantum Filtered 1H MRS at 7 T

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3065-3076, June 2026.
ABSTRACT Purpose 1H MRS lactate measurements are potentially valuable for studying energy metabolism in working skeletal muscle, but some technical obstacles need to be overcome. Spectral filtering to isolate the lactate signal from overlapping lipid resonances shows promise.
