With the development of computed cranial tomography (CCT), many physicians have come to rely on this technique as their sole means of excluding a diagnosis of acoustic neurinoma. In our series of 237 patients with acoustic tumors, 29% of tumors were not detected by CCT. New thin-section scanners improve this detection rate. Tumors within the internal auditory canal, however, will not be detected without special techniques. We recommend that contrast studies of the posterior fossa be employed to exclude definitely the diagnosis of acoustic tumor when one is suspected.
随着计算机头颅断层扫描（CCT）技术的发展，许多医生已开始依赖这一技术作为排除听神经瘤诊断的唯一手段。在我们收治的237例听神经瘤患者中，29%的肿瘤未被CCT检测出来。新型薄层扫描仪提高了这一检测率。然而，若不采用特殊技术，内耳道内的肿瘤将无法被检测到。当怀疑患有听神经瘤时，我们建议采用后颅窝造影检查以明确排除该诊断。
