Status epilepticus in adults: From etiology to treatment response

open access: yesEpilepsia, EarlyView.
Abstract This study explored the association between etiology of status epilepticus (SE) and treatment responsiveness. Consecutive episodes of nonhypoxic SE in patients ≥14 years old were included. Etiology was classified into acute, remote, progressive, defined electroclinical syndromes, and unknown.

Reevaluating the rule of two's: Age and epidemiological variations in Meckel's diverticulum

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective To evaluate the clinical characteristics, diagnostic modalities, and age‐related variation of Meckel's diverticulum (MD) using data from a nationwide pediatric inpatient database and a single‐center institutional cohort. Methods The Kids' Inpatient Database (KID) for 2016 and 2019 was queried for patients with a principal diagnosis ...

Update to the study protocol, including statistical analysis plan, for the multicentre, randomised controlled OuTSMART trial: a combined screening/treatment programme to prevent premature failure of renal transplants due to chronic rejection in patients with HLA antibodies

open access: yesTrials, 2019
Background Chronic rejection is the single biggest cause of premature kidney graft failure. HLA antibodies (Ab) are an established prognostic biomarker for premature graft failure so there is a need to test whether treatment decisions based on the ...

p‐Brain: A Modular Open‐Source Framework for Automated Quantitative DCE‐MRI of Cerebral Perfusion, Microvasculature, and Blood–Brain Barrier Permeability

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT We present p‐Brain, a modular, open‐source framework for reproducible, automated quantitative DCE‐MRI at scale. Rather than a fixed pipeline, p‐Brain is built from interchangeable stages (ingestion, T1/M0$$ {T}_1/{M}_0 $$ fitting, vascular and tissue ROI extraction, signal‐to‐concentration conversion, kinetic modeling, and quality control ...

Federated learning enables big data for rare cancer boundary detection

open access: yesNature Communications, 2022
Federated ML (FL) provides an alternative to train accurate and generalizable ML models, by only sharing numerical model updates. Here, the authors present the largest FL study to-date to generate an automatic tumor boundary detector for glioblastoma.

Clinical Soma and Neurite Density Imaging (SANDI): Translational Microstructure Mapping on Clinical 3T MRI Scanners

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The Soma and Neurite Density Imaging (SANDI) model enables characterization of gray matter (GM) microstructure by estimating soma and neurite signal fractions, but its clinical applicability is limited by the need for multi‐shell acquisitions (at least five b‐values up to 6000 s/mm2), requiring high‐gradient MRI systems. We developed a

The Impact of Water Exchange on Estimates of Myocardial Blood Flow and Extracellular Volume Fraction Using Dynamic Contrast‐Enhanced MRI in Patients Treated for Severe Aortic Stenosis

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate the impact of intra/extracellular water exchange (WX) on quantitative dynamic contrast‐enhanced (DCE) MRI in patients with severe aortic stenosis (AS). The aims were to compare low‐dose (WX insensitive) and high‐dose (WX sensitive) DCE‐MRI measurements, and to compare data acquired before and after aortic valve ...

Towards Faster Fetal 3D CINE Cardiac MRI Reconstruction Using Region‐Optimized Virtual Coils (ROVir)

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate, in a feasibility study, a computationally efficient image‐reconstruction pipeline for 3D balanced steady state free precession (bSSFP) CINE fetal cardiac MRI that reduces radial streaking artifacts, increases effective temporal resolution, and improves diagnostic image quality compared with previous work ...
