Visualization of the saccule and utricle with non-contrast-enhanced FLAIR sequences.

Objectives: 3D-fluid attenuation inversion recovery (FLAIR) collected 4 h after intravenous gadolinium injection can delineate the perilymphatic space (PLS) from the endolymphatic space (ELS) to capture endolymphatic hydrops, the pathological counterpart of Ménière's disease. We aimed to optimize visualization of such inner ear internal anatomy using 3D-FLAIR without injection.

Methods: 3D-FLAIR signal from different fluid compartments such as PLS and ELS was first simulated.

Probing the in-air growth of large area of 3D functional structures into a 2D supramolecular nanoporous network.

Surface-confined host-guest chemistry at the air/solid interface is used for trapping a functionalized 3D Zn-phthalocyanine complex into a 2D porous supramolecular template allowing the large area functionalization of an sp2-hybridized carbon-based substrate as evidenced by STM, resonance Raman spectroscopy, and water contact angle measurements.
