A Simple, Dynamic Geometric Phantom for MRI and CT Reconstruction Pipelines: Beyond Shepp–Logan

Magnetic Resonance in Medicine, EarlyView.
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.

“Two‐For‐One”: 4D Cardiac and Pulmonary MR Imaging From a Single Acquisition Using bSTAR

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To generate 4D (3D+time) images of both the heart and lungs using a single volumetric radial free‐breathing bSSFP dual echo acquisition (bSTAR) with two image reconstructions within a single pipeline deployed inline at 0.55 and 1.5 T.

3D and 4D Free‐Breathing Abdominal T1‐Weighted MRI in Clinical Practice Using Deep Learning Auto‐Navigation and Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate an automated clinical prototype for a 1‐min free‐breathing T1‐weighted 3D MRI and a 2.25‐min 4D MRI utilizing radial k‐space acquisition and deep learning (DL) auto‐navigation and reconstruction. Methods The clinical prototype was deployed on 3 T GE Healthcare scanners, using the GE DISCO‐Star (radial golden ...

Adapted Linear Binning Method to Assess Pulmonary Ventilation and Perfusion in Children Using Lung Matrix Pencil Decomposition (MP)‐MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To adapt and validate a linear binning technique, developed for hyper‐polarized 129Xe MRI, for functional lung MRI with matrix‐pencil decomposition (MP)‐MRI. Methods First, a dedicated normalization was applied to the perfusion‐weighted and the ventilation‐weighted map histograms.

Review of Congenital Myasthenic Syndrome Caused by Pathogenic Variants in GFPT1

Muscle &Nerve, EarlyView.
ABSTRACT Glutamine:fructose‐6‐phosphate transaminase 1 (GFPT1) catalyzes the first and rate‐limiting step of the hexosamine biosynthetic pathway (HBP) to generate UDP‐GlcNAc. GFPT1 exon 9 is specifically spliced in in striated muscles, which makes a long isoform of GFPT1 (GFPT1‐L).

Myasthenia Gravis and Thymoma

Muscle &Nerve, EarlyView.
ABSTRACT Thymoma is the most common tumor of the anterior mediastinum. Approximately 20%–30% of patients with a thymoma develop myasthenia gravis (MG), and an additional one third may possess positive acetylcholine receptor (AChR) antibodies without MG.

Targeted Muscle Reinnervation for Intuitive Prosthetic Control

Muscle &Nerve, EarlyView.
ABSTRACT The convergence of medical and technological advances has led to a substantial expansion of therapeutic approaches for patients with limb amputations. Targeted muscle reinnervation (TMR) is one of the strategies to improve control of bionic arms and has been applied for more than two decades. Through surgical rewiring of the nerves responsible
