Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

open access: yesThe Laryngoscope, EarlyView.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

open access: yesLaser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Imaging Venous Transit Time and Blood–Brain Barrier Permeability of the Deep Brain

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Imaging of venous vessels with advanced pulse sequences allows the assessment of important hemodynamic parameters. Previous work has measured venous transit time (VTT) and blood–brain barrier (BBB) water permeability in cortical tissue.
