Visualization of endolymphatic hydrops became possible after intravenous gadolinium (Gd) injection in patients with Ménière's disease.
To visualize endolymphatic hydrops after intravenous Gd injection.
Gd (gadoteridol; 0.2 mmol/kg) was injected intravenously in three patients with unilateral Ménière's disease. We performed three-dimensional fluid attenuated inversion recovery (3D-FLAIR) and three-dimensional real inversion recovery (3D-real IR) magnetic resonance imaging (MRI) 4 h after the injection using a 3-Tesla MRI unit. We used a 32-channel array coil to obtain a high signal-to-noise ratio.
Endolymphatic hydrops was observed in the ears of patients with Ménière's disease. However, Gd concentration in the perilymph was lower compared with that obtained after intratympanic Gd injection.
梅尼埃病患者静脉注射钆（Gd）后，内淋巴积水变得可以可视化。
在静脉注射Gd后使内淋巴积水可视化。
对3例单侧梅尼埃病患者静脉注射Gd（钆特醇；0.2 mmol/kg）。注射后4小时，使用3特斯拉磁共振成像（MRI）设备进行三维液体衰减反转恢复（3D-FLAIR）和三维真实反转恢复（3D-real IR）磁共振成像。我们使用32通道阵列线圈以获得高信噪比。
在梅尼埃病患者的耳中观察到内淋巴积水。然而，与鼓室内注射Gd后相比，外淋巴中的Gd浓度较低。
