BACKGROUND
The 3D-REAL-IR MRI sequence allows for an in vivo visualization of endolymphatic hydrops. Qualitative assessment methods of the severity of vestibular and cochlear hydrops are the most commonly used.
METHODS
A quantitative volumetric measurement of vestibular EH in patients with definite unilateral Ménière's disease using the 3D-REAL-IR sequence and the calculation of the endolymphatic ratio (ELR) was intended.
RESULTS
Volumetric calculations of the vestibules, vestibular endolymph and vestibular ELR are performed in 96 patients with unilateral Ménière's disease and correlated with classic qualitative grading scales.
CONCLUSIONS
Quantitative volumetric measurement of vestibular hydrops using the 3D-REAL-IR sequence is feasible and reproducible in daily clinical practice. Vestibular ELR values exceeding 60% defined radiologically significant vestibular hydrops, while values below 30% defined radiologically non-significant vestibular hydrops.
背景
3D-REAL-IR MRI序列可实现内淋巴积水的活体可视化。前庭和耳蜗积水严重程度的定性评估方法是最常用的。
方法
旨在使用3D-REAL-IR序列对确诊为单侧梅尼埃病的患者进行前庭内淋巴积水的定量容积测量，并计算内淋巴比率（ELR）。
结果
对96例单侧梅尼埃病患者进行了前庭、前庭内淋巴和前庭ELR的容积计算，并与经典的定性分级量表进行了相关性分析。
结论
在日常临床实践中，使用3D-REAL-IR序列对前庭积水进行定量容积测量是可行且可重复的。放射学上，ELR值超过60%定义为显著前庭积水，而值低于30%定义为非显著前庭积水。
