Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

open access: yesLaser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.

Modular Polymers With Tuneable Charge and Amphiphilicity for Effective Antimicrobial Photodynamic Therapy

open access: yesMacromolecular Rapid Communications, EarlyView.
A modular dual‐strategy platform combining free radical copolymerisation and post‐polymerisation modification yields a library of ruthenium‐functionalised polymers for antimicrobial photodynamic therapy. Tuneable composition and net charge govern activity against multidrug‐resistant Pseudomonas aeruginosa biofilms and Staphylococcus aureus under ...

Ultimate Intrinsic SNR Depends on B0 Orientation

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This work aims to investigate the effect of B0$$ {B}_0 $$ orientation on the uiSNR in MRI. Methods Electromagnetic simulations were performed on both realistic body models and simplified geometric models. Comparisons between (1) opposite B0$$ {B}_0 $$ directions along the head‐foot (HF) axis, corresponding to head‐first and feet‐first ...

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

open access: yesMagnetic 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

A Modular Hybrid Framework for CEST MRI Development and Clinical Translation Using pTx‐Pulseq Preparation With Open‐ and Closed‐Source Readouts and ONNX Mapping

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Chemical exchange saturation transfer (CEST) MRI offers unique metabolic insights for imaging of cancer, stroke, or neurodegeneration. However, the rapid expansion of CEST preparation schemes and evaluation techniques creates a bottleneck; novel methods often remain complex prototypes requiring offline processing, preventing clinical ...

Strain Rate Angle Distribution as an Indicator of Post‐Infarct Myocardial Remodeling: Proof‐of‐Concept of a Novel Application of the MRI Derived Strain Rate Tensor Field

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Left ventricular (LV) strain is an early indicator of myocardial dysfunction. However, conventional strain metrics do not fully account for the multidirectional nature of myocardial deformation. The strain rate tensor, derived from velocity‐encoded MRI, represents the time‐resolved magnitude and direction of strain rate without the ...

Weakly Convex Ridge Regularization for 3D Non‐Cartesian MRI Reconstruction

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose While highly accelerated non‐Cartesian acquisition protocols significantly reduce scan time, they often entail long reconstruction delays for 3D data. Deep learning–based reconstruction methods can alleviate this, but typically rely on complex, highly parametrized architectures.
