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.

A Sinc method for an eigenvalue problem of a differential operator with periodic coefficients and its comparison with Hill's method

We consider a problem of computing spectrum of an ordinary differential operator with periodic coefficients. Due to Floquet's theory, such a problem is reduced to a set of eigenvalue problems for modified operators with a periodic boundary condition.

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.

Ferumoxytol‐Enhanced Myocardial T1 Tracking Using a Hybrid 2D/3D Steady‐State MRI Sequence Captures Cyclic Intramyocardial Blood Volume Dynamics

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
Cyclic changes in intramyocardial blood volume (iMBV) from systole to diastole can mark coronary disease without the need for vasodilator stress. We present a ferumoxytol‐enhanced MRI technique using a new continuous pulse sequence that effectively tracks cyclic myocardial T1 changes.
