Abstract

• T1W-3D-TSE with variable refocusing flip angles are used to diagnose iVAD. • Susceptibility artifacts of the cavernous sinus may cause vessel wall defects. • 3D PSIR reconstructs images while maintaining signal polarity through phase correction. • 3D-PSIR improved the vessel wall defects caused by the susceptibility artifacts. • 3D-PSIR achieved MRI findings comparable to those of the T1W-3D-TSE in iVAD. T1-weighted 3D turbo spin echo (T1W-3D-TSE) sequences with variable refocusing flip angle are commonly used to diagnose intracranial vertebrobasilar artery dissection (iVAD). However, magnetic susceptibility artifacts of the cavernous sinus may cause loss of the basilar and vertebral arteries. This study investigated the effectiveness of a 3D phase-sensitive inversion recovery (3D-PSIR) sequence in reducing magnetic susceptibility artifacts in the cavernous sinus, and its imaging findings for iVAD. Twelve volunteers and eleven patients with iVAD were included. Magnetic resonance imaging (MRI) was performed using a 3.0-T MRI system. 3D-PSIR and T1W-3D-TSE sequences were used. Vessel wall defects and contrast-to-noise ratio (CNR) were evaluated. The MRI findings were visually evaluated. In the 3D-PSIR images, one volunteer (8 %) had vessel wall defects, and five (42 %) had vessel wall defects (p = 0.046) in the T1W-3D-TSE images. CNR was higher in 3D-PSIR images for vessel wall-to-lumen, whereas it was higher in T1W-3D-TSE images for vessel wall-to-CSF (p < 0.001). Visual evaluation revealed similar MRI findings between the two sequences. The 3D-PSIR sequence may be able to improve the vessel wall defects and achieve MRI findings comparable to those of the T1W-3D-TSE sequence in iVAD. The 3D-PSIR sequence can be a useful tool for the imaging-based diagnosis of iVAD. [ABSTRACT FROM AUTHOR]

48. Effects of Superomedial Partial Arytenoidectomy on Incomplete Posterior Glottal Closure Caused by Arytenoid Positional Asymmetry in Excised Human Larynges.

Abstract

To analyze the effects that arytenoid positional asymmetry has on posterior glottic closure and to determine whether superomedial partial arytenoidectomy (SPA) can provide a benefit in cases of such asymmetry. In this experimental study, we evaluated posterior glottic closure in 10 larynges freshly excised from human cadavers, measuring the distance between the vocal processes before and after artificially simulated positional asymmetry of the arytenoid cartilages. We then performed SPA, after which we again measured the distance between the vocal processes. In all of the larynges studied, the posterior glottic closure went from complete to incomplete after simulation of arytenoid positional asymmetry, the median distance observed between the vocal processes being 1.74mm (interquartile range 0.22). The SPA performed after arytenoid asymmetry caused the posterior glottic closure to return from incomplete to complete in all of the larynges studied. Our results suggest that arytenoid positional asymmetry impairs posterior glottic closure and that SPA improves posterior glottic closure in such cases of arytenoid asymmetry. [ABSTRACT FROM AUTHOR]
