Regularized Joint Reconstruction and Slab Combination for Accelerated Three‐Dimensional Multi‐Slab Diffusion‐Weighted Imaging Using Multi‐Scale Energy Models

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To jointly reconstruct high‐resolution diffusion‐weighted volumes and eliminate slab‐boundary artifacts while preserving fine anatomical detail from undersampled 3D multi‐slab k‐space acquisitions. Methods A bilinear forward model was formulated to describe the 3D multi‐slab acquisition, treating the image volume and slab excitation ...

Brain Clearance of Contrast Agent in Intravenous DCE‐MRI Is Measurable and Cannot Be Explained by Clearance Across the BBB Alone

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To determine the feasibility of measuring brain clearance of gadolinium contrast agent using standard intravenous DCE‐MRI acquisitions and evaluate the contribution of blood–brain barrier (BBB) and non‐BBB clearance routes. Methods Uptake and extended Tofts models were fit to DCE‐MRI data from people with Parkinson's disease, post ...

Imaging of Facial Muscles in Facioscapulohumeral Muscular Dystrophy: An Exploratory Study Comparing Magnetic Resonance Imaging and Ultrasound

Muscle &Nerve, EarlyView.
ABSTRACT Aims Facioscapulohumeral muscular dystrophy (FSHD) is a genetic progressive muscle disorder often presenting with facial weakness. However, imaging studies specifically evaluating facial muscle involvement and its relationship with clinical severity remain limited. This preliminary study explored magnetic resonance imaging (MRI) and ultrasound

Preoperatively Diagnosed Versus Undiagnosed Major Salivary Gland Cancer: Clinicopathological Characteristics, Treatment Strategies, and Oncological Outcomes

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To evaluate differences in clinicopathological characteristics, treatment strategies, and oncological outcomes between preoperatively diagnosed and undiagnosed major salivary gland cancers (MSGCs). Study Design Retrospective cohort study. Setting A single tertiary academic hospital. Methods Surgically confirmed MSGCs between 2012 and

Artificial intelligence, equity, and pediatric neurodevelopmental disorders: A scoping review of clinical practice applications

Pediatric Investigation, EarlyView.
Artificial intelligence (AI) is being explored to support diagnosis and care for pediatric neurodevelopmental disorders, yet most tools remain in early stages of development. This scoping review identifies limited external validation, narrow population representation, and sparse equity considerations, underscoring the need for inclusive, clinically ...

Micro Partial Discharge Characteristics of SF6 Under DC Voltage

High Voltage, EarlyView.
ABSTRACT In gas‐insulated high‐voltage direct current (HVDC) devices, micro partial discharges (PD) caused by micro‐protrusions or surface roughness on conductors or enclosures may not cause immediate insulation system failure due to their weak discharge intensity.

Associations of cannabis use, tobacco use and co‐use with brain volume: A systematic review and meta‐analysis

Addiction, EarlyView.
Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Anticoagulation Strategies in Adults Undergoing Extracorporeal Membrane Oxygenation: A Systematic Review and Meta‐Analysis

Artificial Organs, EarlyView.
In this meta‐analysis of 2 775 adult ECMO patients from non‐randomized studies, direct thrombin inhibitors and low‐molecular‐weight heparins demonstrated a favorable efficacy and safety profile over unfractionated heparin. These findings suggest them to be effective alternatives to unfractionated heparin, underscoring the urgent need for randomized ...
