Abstract
Objective To evaluate the value of CT and magnetic resonance imaging ( MRI) in the Diagnosis of ves-tibular 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 ima-ges 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 bi-lateral 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. Conclu-sion Accurate diagnosis of LVAS could be made both on CT and MRI. CT is the main display VA bony structure expanding,indirectly showed enlarged VA;MRI can directly show the expanded VA and ES.关键词
