BACKGROUND AND PURPOSE: Elevated protein levels have been reported in perilymph of patients with vestibular schwannoma. Fluid-attenuated inversion recovery (FLAIR) imaging is sensitive to high protein contents in fluids. The purpose of this study was to investigate if in patients with unilateral vestibular schwannoma, cochlear FLAIR signal intensity on the affected side is increased compared with the unaffected side and control subjects.

“…[21][22][23][24][25][26][27][28][29][30] A FLAIR image allows the detection of subtle subarachnoid hemorrhage in the CSF space, 9 signal increases in CSF after the inhalation of oxygen, 31 and subtle compositional changes of the labyrinthine fluid (Figs. 6 and 7), 26,27,30,[32][33][34] which can be difficult to recognize on T 1 -weighted images. Heavily T 2 -weighted 3D-FLAIR has been reported to be much more sensitive than regularcontrast 3D-FLAIR.…”

“…63 Prognosis for hearing was not good in ears with a high signal on precontrast 3D-FLAIR. 65,66 Inflammation A signal increase in the labyrinthine fluid on 3D-FLAIR in various inflammatory diseases such as acute meningitis, acute otitis media, Wegener's granulomatosis, 27 mumps deafness, 26 RamsayHunt syndrome, [67][68][69] and labyrinthine fistula by a cholesteatoma 70 has been reported. Signal increase in the labyrinthine fluid on precontrast 3D-FLAIR suggests the presence of a small degree of hemorrhage or protein, and on post-contrast 3D-FLAIR, enhancement of the labyrinthine fluid suggests the active breakdown of the blood-labyrinthine barrier.…”

In clinical MR neuroimaging, 3D fluid-attenuated inversion recovery (3D-FLAIR) with a variable-flip-angle turbo spin echo sequence is becoming popular. There are more than 100 reports regarding 3D-FLAIR in the PubMed database. In this article, the technical and clinical features of 3D-FLAIR for neuroimaging are reviewed and summarized. 3D-FLAIR allows thinner slices with multi-planar reformation capability, a higher flow sensitivity, high sensitivity to subtle T 1 changes in fluid, images without cerebrospinal fluid (CSF) inflow artifacts, and a 3D dataset compatible with computer-aided analysis. In addition, 3D-FLAIR can be obtained within a clinically reasonable scan time. It is important for radiologists to be familiar with the features of 3D-FLAIR and to provide useful information for patients.

“…[13][14][15][16][17] Furthermore, 3D-FLAIR imaging can minimize the undesired inflow artifacts of CSF flow, has a higher signal-tonoise ratio and spatial resolution, and allows recognition of subtle compositional changes of the inner ear fluid. [18][19][20][21] Therefore, one can assume that the increased protein content in the cochlear perilymph of patients with ANs can be detected on 3D FLAIR imaging with a high sensitivity and good spatial resolution. Several researchers recently investigated whether there was a correlation between the increased cochlear FLAIR signal in patients with ANs and the degree of their hearing disturbance.…”

BACKGROUND AND PURPOSE:The increased cochlear signal on FLAIR images in patients with acoustic neuroma is explained by an increased concentration of protein in the perilymphatic space. However, there is still debate whether there is a correlation between the increased cochlear FLAIR signal and the degree of hearing disturbance in patients with acoustic neuroma. Our aim was to investigate the clinical significance of an increased cochlear 3D FLAIR signal in patients with acoustic neuroma according to acoustic neuroma extent in a large patient cohort.
