听神经瘤是常见颅神经肿瘤之一,占桥小脑角肿瘤的80_+％,其影像诊断方法很多,为探讨低磁场MRI对该肿瘤的诊断价值,本文对表现比较典型的16例,分析如下: 资料和方法 16例中,男10例,女6例,年龄19～63岁,平均43岁,临床症状以单侧耳鸣、听力下降及耳聋为主,病程:2月～19年,平均4.3年,单 Acoustic neuroma is one of the common cranial nerve tumors, which accounts for 80% of the cerebellopontine angle tumors. There are many imaging diagnostic methods. In order to explore the diagnostic value of low magnetic field MRI in this tumor, 16 cases with typical performance are analyzed in this paper as follows: Materials and methods 16 cases, 10 males and 6 females, aged 19 to 63 years, mean 43 years old, clinical symptoms of unilateral tinnitus, hearing loss and deafness, duration: February to 19 years, an average of 4.3 years ,single
