Heavily T(2)-weighted 3-dimensional fluid-attenuated inversion recovery (hT(2)W-3D-FLAIR) technique has been reported to be more sensitive than conventional 3D-FLAIR in detecting low concentrations of gadolinium-based contrast media (GBCM) in fluid. We applied hT(2)W-3D-FLAIR to visualize endolymphatic hydrops of Ménière's disease in 3 patients 4 hours after single-dose intravenous injection of GBCM and successfully visualized endolymphatic hydrops in either the cochlea or vestibule in all patients. This technique can be implemented in a clinical setting.
重 T2 加权三维液体衰减反转恢复（hT2W-3D-FLAIR）技术在检测液体中低浓度钆基对比剂（GBCM）方面比传统的 3D-FLAIR 更敏感。我们在 3 名患者单次静脉注射 GBCM 后 4 小时应用 hT2W-3D-FLAIR 观察梅尼埃病的内淋巴积水，所有患者均成功地在耳蜗或前庭中可视化内淋巴积水。该技术可在临床环境中实施。
