“…A previous study reported that cochlear endolymphatic hydrops could not be visualized by IV-SD-GBCM using 3D-FLAIR and 12-channel head coil at 3T. 5 However, another study using hT 2 W-3D-FLAIR and 32-channel head coil reported visualization of cochlear endolymph, attributable to the increased Magnetic Resonance in Medical Sciences sensitivity to faint contrast enhancement, 6 but the images suŠered more noise than 3D-FLAIR images. In the present study, nondilated cochlear endolymph was not visualized on PEI, perhaps partly due to the small size of the nondilated cochlear endolymph.…”

To visualize endolymph as bright signal after intravenous injection of single-dose gadodiamide, we shortened the inversion time of heavily T 2 -weighted 3-dimensional (3D) ‰uid-attenuated inversion recovery (FLAIR) to 2050 ms. In 14 patients with suspected M áeni àere's disease, we observed high signal of vestibular endolymph in all ears, including 6 ears without vestibular endolymphatic hydrops. We observed high signal of cochlear endolymph in 17 ears with cochlear endolymphatic hydrops but not 11 ears without cochlear endolymphatic hydrops.

“…No study has directly compared the effects of various GBCM for EHI in the same subjects. For IV-Gd, most reports utilized gadodiamide [11,52,58,60], while some used gadoteridol [14,48,61]. Both types of GBCM give similar findings regarding endolymphatic hydrops 4 h after the administration of IV-Gd, and there appears to be no major differences in the effects on perilymph contrast.…”

Visualization of endolymphatic hydrops with MR imaging in patients with Ménière’s disease and related pathologies: current status of its methods and clinical significance

Ménière's disease is an inner ear disorder characterized by vertigo attacks, fluctuating low-frequency hearing loss, ear fullness, and tinnitus. Endolymphatic hydrops has long been thought to be the pathological basis for Ménière's disease. Some patients have inner ear symptoms that do not match the diagnostic guidelines for Ménière's disease, and these are also thought to be related to endolymphatic hydrops. The diagnosis of endolymphatic hydrops is usually made based on clinical symptoms with some assistance from otological functional tests. Recently, the objective diagnosis of endolymphatic hydrops by MR imaging has become possible and many research results have been reported regarding the imaging methods, evaluation methods, the correlation between imaging results and functional otological tests and the correlation between imaging findings and clinical symptoms. In this article we summarize the development of current imaging methods, evaluation techniques and clinical reports based on a review of the literature. We also attempt to characterize the current significance and future directions of MR imaging of endolymphatic hydrops.

Familiarity with these features of 3D-FLAIR imaging and proper use of 3D-FLAIR are important in order for radiologists to obtain useful information for patient management.…”

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.
