Metasurfaces in Adaptive Optics: A New Opportunity in Optical Wavefront Sensing

open access: yesLaser &Photonics Reviews, EarlyView.
Wavefront sensing constitutes a critical component of adaptive optics systems, aimed at quantitatively measuring distorted wavefronts and enabling closed‐loop correction in optical setups. Metasurfaces, as planar optical elements composed of nanoscale structures, provide exceptional freedom in modulating multiple dimensions of the light field.

Comparison of cardiac diffusion MRI using multiple prospective respiratory motion correction techniques

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose A novel prospective motion correction control system with slice tracking (MNav‐CoS) was compared with three other prospective respiratory motion correction techniques in performing free‐breathing cardiovascular diffusion tensor imaging (cDTI) acquisitions. Methods Ten healthy volunteers underwent cDTI using an M2SE sequence.

Free‐breathing 3D pulmonary ventilation mapping at 0.55 T using stack‐of‐spiral out‐in bSSFP

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a free‐breathing pulmonary imaging technique that provides three‐dimensional (3D) structural images and regional ventilation maps, and to evaluate its repeatability and accuracy compared with two‐dimensional phase‐resolved functional lung (PREFUL) and global tidal volume.

Genetic Diagnosis and Clinical Features of Fetuses With Congenital Diaphragmatic Hernia

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective Congenital diaphragmatic hernia (CDH) is a rare abnormality with highly heterogeneous genetic causes. This study investigated chromosomal and monogenic abnormalities in fetal CDH patients and evaluated the efficacy of chromosomal microarray analysis (CMA) and whole‐exome sequencing (WES) for genetic diagnosis.

Assessment of Double Outlet Left Ventricle in Pediatrics Using Transthoracic Echocardiography and Computed Tomographic Angiography

open access: yesPediatric Discovery, EarlyView.
The clinical manifestation of DOLV was atypical. TTE has a relatively high diagnostic accuracy for DOLV in pediatric, which is very valuable for its early detection. ABSTRACT Double outlet left ventricle (DOLV) is a rare congenital cardiac anomaly in which both great arteries originate entirely or predominantly from the morphologic left ventricle.
