Clinical value of 4‐hour delayed gadolinium‐Enhanced 3D FLAIR MR Images in Acute Vestibular Neuritis

Objective To investigate the clinical significance of 4‐hour delayed‐enhanced 3.0 Tesla three‐dimensional (3D) fluid‐attenuated inversion recovery (FLAIR) magnetic resonance (MR) imaging in acute vestibular neuritis.

Description
Summary:Objective To investigate the clinical significance of 4‐hour delayed‐enhanced 3.0 Tesla three‐dimensional (3D) fluid‐attenuated inversion recovery (FLAIR) magnetic resonance (MR) imaging in acute vestibular neuritis. Study Design A prospective observational study. Methods Twenty‐nine vestibular neuritis patients were enrolled between January 2017 and June 2017. Vestibular function tests, comprising the caloric and video head impulse tests and vestibular‐evoked myogenic potential measurements, were performed. Precontrast, 10‐minute, and 4‐hour delayed‐enhanced 3D‐FLAIR MR images using double‐dose IV gadolinium were obtained. After laterality and extent of inner ear enhancement were defined, the patients were divided into groups based on the patterns of enhancement, and clinical parameters were analyzed according to the groups. Results Twenty patients (20 of 29, 69.0%) had obviously asymmetric enhancement of the affected inner ear structures on 4‐hour delayed images, whereas only three patients (10.3%) had marked enhancement on 10‐minute delayed images. The duration of spontaneous nystagmus (DurSN) was significantly longer in the patients with enhancement, especially with enhancement of the whole inner ear, including the vestibule and semicircular canals (P
