View Order With Arbitrary Center Echoes
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

Purpose Chemical exchange saturation transfer (CEST) and chemical exchange‐sensitive spin‐lock (CESL) MRI enable spectroscopic imaging with high sensitivity, but conventional analysis methods often fail as exchange approaches the fast‐exchange limit.

A Simple, Dynamic Geometric Phantom for MRI and CT Reconstruction Pipelines: Beyond Shepp–Logan
ABSTRACT A customizable, dynamic geometric phantom was developed to bridge the gap between simplistic static phantoms and highly realistic, complex 4D solutions. The phantom enables initial testing, helps detect implementation errors, and supports quantitative evaluation of new dynamic acquisition and reconstruction methods.

Suppression of Oscillation and Ghosting in RF‐Spoiled Gradient‐Echo‐Based Dynamic Imaging
ABSTRACT PurposeThis study aims to address the suppression of oscillation and ghosting appearing in RF‐spoiled gradient‐echo‐based dynamic imaging, which is caused by the pseudo‐steady state (PSS) of magnetization. Theory and MethodsWe extended the concept of the previous RF phase‐cycle‐adapted averaging method to RF‐spoiled gradient‐echo‐based cine ...

ABSTRACT Purpose Magnetic Resonance Fingerprinting (MRF) enables rapid quantitative imaging, but high‐resolution 3D reconstructions remain computationally expensive due to the NUFFTs required at every iteration, and the commonly used Locally Low Rank (LLR) regularization becomes ineffective at high acceleration.

ABSTRACT Purpose To develop a unified image reconstruction framework that bridges real‐time and gated cardiac MRI, including quantitative MRI. Methods We introduce generative multitasking, which learns subject‐ and dataset‐specific implicit neural temporal bases from sequence timings and an interpretable latent space for cardiac and respiratory motion.

Combined ADC and T2 Mapping in the Prostate Using a 3D Reduced FOV Sequence
ABSTRACT Purpose To develop a 3D reduced FOV sequence for combined ADC and T2 mapping in the prostate in a single scan. Methods A 3D ADC and T2 mapping reduced FOV acquisition is enabled using T2 and diffusion preparation modules with slab‐selective tip‐down pulses and magnitude stabilizer gradients.
