An Inline‐Integrable Image Restoration Model With ROI Fine‐Tuning and Slice‐to‐Volume Reconstruction for Accelerated Whole‐Brain Vessel Wall Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a vessel wall imaging (VWI)‐dedicated image restoration model enabling high‐resolution whole‐brain VWI in under 6 min. Methods A transformer‐based 2.5D model was trained in a supervised manner to enhance the image quality of CAIPIRINHA 2 × 2‐accelerated VWI acquisitions to a level comparable to that of GRAPPA twofold ...

Cross‐Platform Demonstration of an Autonomous MRI Field Camera

Magnetic Resonance in Medicine, EarlyView.
Purpose Recent work has proposed self‐synchronization, self‐calibration, and means of sequence parsing to enhance the versatility of field cameras. The purpose of this paper is to expand this approach to more complex sequences and verify feasibility across distinct scanner platforms.

From Breath‐Hold to Free‐Breathing: Possibilities in High‐Resolution Quantitative Susceptibility Mapping (QSM) of the Kidney With Respiratory Gating

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to assess the feasibility of QSM in the human kidney during free‐breathing using respiratory gating for motion compensation. Methods Renal imaging of 15 healthy volunteers was performed using an axial multi‐echo GRE sequence on a 3 T MRI scanner.

Whole‐Brain Cerebral Microvascular Pulsatility Imaging Using Dynamic pCASL MRI With Segmented Stack‐of‐Stars Golden‐Angle Radial Acquisition

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an efficient dynamic pseudo‐continuous arterial spin labeling (pCASL) MRI technique for whole‐brain microvascular flow pulsatility imaging. Methods The proposed technique combines pCASL with a segmented stack‐of‐stars golden‐angle radial acquisition.

Simultaneous T1 and T2 Mapping in the Brain With QuantoRAGE: An MP2RAGE Variant Using T2‐Prepared Inversion

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate a repeatable and reproducible approach, QuantoRAGE, for simultaneous whole‐brain T1 and T2 mapping using adiabatic magnetization preparation. Methods QuantoRAGE is a 3D FLASH‐based sequence using an adiabatic T2‐prepared inversion followed by two readout blocks.

An Adaptive Metasurface for Adjustable Magnetic Resonance Imaging Enhancement at 3 T and 7 T: A Feasibility Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high field (≥ 7 T) and 3 T MRI suffer from B1+ inhomogeneity and signal loss. Conventional metasurfaces that mitigate B1+ inhomogeneity and improve image SNR are “fixed” in nature and designed for a single Larmor frequency. This study demonstrates the feasibility of an adaptive metasurface utilizing voltage‐controlled capacitors ...
