| 摘 要： | 目的探讨CT联合MRI技术在感音神经性耳聋检查中的价值。方法收集临床表现为感音性耳聋病人75例。同时采用CT及MRI检查，在相应的后处理工作站上进行MPR、MIP及VR重建处理，分析两种检查方法的Kappa一致性。并在MRI上对其中正常内耳的主要结构进行数据测量，对不同侧别、不同性别的内耳进行分析。结果75例中，30例未见异常，其不同侧别、不同性别内耳各测量值差异均无统计学意义（P>0.05）。45例耳结构异常，包括半规管畸形3例，耳蜗畸形4例，前庭导水管扩大9例，内听道畸形4例，外耳道异常2例，蜗神经发育不良18例，内听道血管发育异常5例。两种检查方法对检出半规管畸形、耳蜗畸形、大前庭导水管综合征的一致性较好，内听道畸形的一致性较差。结论CT、MRI两种检查方法诊断感音神经性耳聋各有优势，相辅相成，为临床提供可靠的影像学依据，具有重要的临床应用价值。

| Abstract: | ObjectiveTo investigate the value of CT combined with MRI in the examination of sensorineural hearing loss.MethodsSeventy-five patients with sensorineural hearing loss were examined with CT and MRI at the same time.MPR, MIP and VR were reconstructed with the corresponding post-processing workstation, and the Kappa consistency of the two methods was analyzed.The main structures of the normal inner ear were measured with MRI, and the inner ears of different sides and genders were analyzed.ResultsAmong 75 patients, thirty cases were normal, and there was no significant difference in the measurement values of the inner ear of different sides and genders (P>0.05).Forty-five cases with abnormal ear structure were found, including 3 cases of malformation of semicircular canal, four cases of cochlear deformity, nine cases of enlarged vestibular aqueduct, four cases of malformation of internal auditory canal, two cases of abnormal external auditory canal, eighteen cases of cochlear nerve dysplasia, and five cases of abnormal vascular development of internal auditory canal.The consistency of the two methods in detecting semicircular canal malformation, cochlear malformation and large vestibular aqueduct syndrome was better, but the consistency of detecting internal auditory canal malformation was poor.ConclusionsCT and MRI have their own advantages in the diagnosis of sensorineural hearing loss.They complement each other, can provide reliable imaging basis for clinical practice, and have important clinical application value. |
