CT is--especially since the introduction of thin slice technique--the method of choice for the diagnosis of nasopharyngeal tumors. This method provides better results than the conventional film tomography in determining intracranial tumor extension, osseous destruction of the base of the skull, and involvement of the orbit. Tumor infiltration into the pterygoid fossa is also well seen by the third generation of CT. In particular CT scans are superior to conventional tomography in delineating tumor extension to the parapharyngeal and retromaxillary space as well as in recognition of cervical lymph node involvement.
自从薄层技术引入以来，CT尤其是诊断鼻咽癌的首选方法。在确定颅内肿瘤扩展、颅底骨质破坏以及眼眶受累情况方面，该方法比传统的断层摄影术能提供更好的结果。第三代CT也能很好地显示肿瘤向翼腭窝的浸润。特别是在描绘肿瘤向咽旁间隙和上颌后间隙的扩展以及识别颈部淋巴结受累方面，CT扫描优于传统断层摄影术。
