To study the effect of the magnetic resonance hydrography of inner ear technique in diagnosing large vestibular aqueduct syndrome.
3D-Fast Advanced Spin Echo MR imaging was performed on the petrosal bone of the patient who suffered from large vestibular aqueduct syndrome(LVAS). Then all the original images were transferred to an online workstation and underwent image postprocessing. The 3D images of the inner ears were obtained after 3D reconstruction.
The MR hydrography of inner ear of the patient displayed that there was an extradural high-signal intumescence which was like silver shape and the edge of it was smooth and neat between the sigmoid sinus of the posterior cranial fossa and the inner acoustic meatus. The maximum width of the mid position of endolymphatic sac in the temporal bone of the patient was 2.470 mm. This was much bigger than the diagnosis standard of the large vestibular aqueduct syndrome with ordinary MR imaging.
The MR hydrography technique is an effective method to diagnose large vestibular aqueduct syndrome. The final diagnosis in clinic could be made with the assistance of this technique.
研究内耳磁共振水成像技术在诊断大前庭导水管综合征中的作用。
对患有大前庭导水管综合征(LVAS)的患者颞骨进行三维快速进阶自旋回波磁共振成像。然后将所有原始图像传输至在线工作站并进行图像后处理。经三维重建后获得内耳的三维图像。
患者内耳磁共振水成像显示,在后颅窝乙状窦与内耳道之间有一硬膜外高信号肿物,呈银形,边缘光滑整齐。患者颞骨内淋巴管囊中部最大宽度为2.470毫米。这比普通磁共振成像诊断大前庭导水管综合征的标准大得多。
磁共振水成像技术是诊断大前庭导水管综合征的有效方法。借助该技术可在临床上做出最终诊断。
