| 目的探讨CT和MRI在诊断大前庭导水管综合征（LVAS）中的应用价值以及两者的优势比较。方法20例LVAS患者行HRCT和3.0TMRI检查。在CT横断位图像上测量前庭水管（VA）中点最宽径，并应用体积重塑（VR）三维重组技术；MRI检查均使用3D——FIESTA序列，在MRI横断位图像上测量内淋巴囊（ES）骨内部分中点最宽径,并应用VR三维重组技术。结果20例LVAS患者CT均显示双侧扩大的VA；MRI显示双侧扩大的ES和VA。CT和MRI测量其前庭总脚到前庭导水管外口之间的中点位置最大的管径宽度均大于1.5mm。 |

| Objective To evaluate the value of CT and magnetic resonance imaging （MRI） in the Diagnosis of vestibular aqueduct syndrome（LVAS）and compare their advantages. Methods CT and MRI were performed on 20 cases with LVAS.The Largest diameter of the midpoint of Vestibular aqueduct（VA） on cross section images of CT and Volume rendering （VR） technique was used for three-dimension reformation.3D-FIESTA sequence was used on MRI.The largest diameter of midpoint were measured on cross section images and VR technique was used as well. Results Bilateral enlargement of VA was showed on CT as well as bilateral enlargement of VA and ES was showed on MRI in all of these 20 patients.The external aperture of Vestibular aqueduct and the intermediate segment width greater than 1.5mm on CT an MRI. Conclusion Accurate diagnosis of LVAS could be made both on CT and MRI.CT is the main display VA bony structure expanding,indirectly showed enlarged VAMRI can directly show the expanded VA and ES. |
