２６例内听道脑池气造影ＣＴ检查中，诊断为听神经瘤４例，３例为内听道小听神经瘤，１例属中型；内听道小囊肿１例；面－听神经血管袢压迫综合征５例；蛛网膜炎２例；１４例ＣＴ表现正常。认为Ｇａｓ－ＣＴＣ检查方法简便，分辨率高，是目前诊断和排除内听道及桥小脑角病变最敏感可靠的方法。结合文献对Ｇａｓ－ＣＴＣ检查方法作了改进。
26 cases of auditory brainstem airway gasography CT examination, diagnosed as acoustic neuroma in 4 cases, 3 cases of small auditory sphincter of acoustic stenosis, 1 case of medium; small intraciliary sphincter in 1 case; surface - auditory neurovascular 袢 oppression synthesis Sign in 5 cases; 2 cases of arachnoiditis; 14 cases of CT showed normal. Gas-CTC is considered as a simple, high-resolution method for the diagnosis and exclusion of the most sensitive and reliable method of internal auditory canal and bridge cerebellar angle lesion. Gas-CTC inspection method was improved in combination with the literature.
