【摘要】 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。更多还原

【Abstract】 Twenty- six patients received gas- CT cisternography(Gas - CTC),4 of them were ill with acoustic neuroma,3 With intracanalicular acoustic neuroma and 1 was mediumsized 1 with cystic meatus acusticus internus,5 with pressure syndrome of facial and acoustic nervous loops,2 with arachnitis and 14 with normal CT appearance.We believe that Gas-CTC is a simple way with high resolving rate.At present,Gas-CTC is the most sensitive and reliable method for diagnosing and eliminating lesions of internal acoustic meatus and cerebellopontine angle.Gas - CTC brain scanning method is improved by referring to some articles listed below.更多还原
