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

Magnetic 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 ...

Optimizing Ex Vivo MRI and Controlling the Roll of the Specimen Using Container‐ and Brain‐Specific 3D‐Printed Holders

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Positioning and stabilizing a specimen in a container in preparation for ex vivo MRI are challenging. In addition, ex vivo MRI is often performed using preclinical scanners with gradient nonlinearity and nonhomogeneous sensitivity, requiring optimal placement.

Spatially Aware Acquisition‐Independent Deep Learning for IVIM MRI Parameter Estimation in Patients With Esophageal Cancer

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Neural controlled differential equations (NCDEs) recently emerged as a robust deep learning approach for quantitative MRI parameter estimation. NCDEs offer flexibility to changes in acquisition protocols by modeling the signal evolution dynamics. However, NCDE implementations operate on a voxel‐by‐voxel basis and cannot exploit spatial

Enhanced 3D Filter‐Exchange Imaging Using Multi‐Slab Acquisition

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Starting from the implementation of a single‐slice FEXI sequence, a 3D method was developed to accelerate a FEXI experiment and acquire a multi‐slice volume. Methods 3D multi‐slab FEXI divides the volume of interest into different slabs.

Comparing Multi‐Pool Lorentzian Fitting Methods for Guanidinium CEST Quantification in the Human Brain at Clinical 3 T: A Validation Study Using MRS

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to evaluate the performance of our recently proposed double‐step multi‐pool Lorentzian fitting (DMPLF) method for extracting GuanCEST and other CEST signals in the human brain at clinical 3 T, using MRS as the reference standard.

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

The Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

DUCK‐Net: automated deep learning segmentation of ductular reactions in murine liver injury captures multicellular niche dynamics from H&E morphology

The Journal of Pathology, EarlyView.
Abstract Ductular reactions (DRs) are dynamic and complex multicellular responses that occur as a result of various hepatic injuries. Precise identification and quantification of the extent of DRs is a cornerstone of pre‐clinical modelling of liver disease, with links to inflammation, fibrosis, regeneration, and disease severity.

The characterization of dysphagia in COVID‐19 rehabilitation patients: An inpatient rehabilitation cohort study

PM&R, EarlyView.
Abstract Background Severe COVID‐19 infection requiring hospitalization is associated with oropharyngeal dysphagia, yet trajectories in the inpatient rehabilitation facility (IRF) setting remain undercharacterized. Objective To investigate the prevalence, risk factors, recovery likelihood, and evolution of dietary requirements of patients with ...
