Examinations used to search for unknown primary tumors of squamous cell carcinomas of the neck include CT, MRI, laryngoscopy, gastrointestinal endoscopy, and positron-emission tomography (PET). Narrow band imaging (NBI) endoscopy in which an optical color-separation filter is used to narrow the bandwidth of spectral transmittance is also used.
Twenty-eight patients in whom primary squamous cell carcinomas could not be detected with conventional white light laryngoscopy underwent NBI endoscopy and PET.
Primary lesions were detected with NBI endoscopy in 3 patients, but no primary lesions were detected with PET. However, PET was used to detect a lower gingival cancer and a palatine tonsillar cancer.
Both PET and NBI endoscopy is effective for detecting unknown primary tumors of squamous cell carcinomas of the neck.
用于寻找颈部鳞状细胞癌未知原发性肿瘤的检查包括 CT、MRI、喉镜、胃肠内窥镜和正电子发射断层扫描（PET）。窄带成像（NBI）内窥镜也可用于检查，其中使用光学颜色分离滤波器来缩小光谱透射带宽。
28 例常规白光喉镜检查无法发现原发性鳞状细胞癌的患者接受了 NBI 内窥镜和 PET 检查。
NBI 内窥镜检查发现 3 例原发性病变，但 PET 检查未发现原发性病变。然而，PET 用于检测下牙龈癌和腭扁桃体癌。
PET 和 NBI 内窥镜检查均对颈部鳞状细胞癌的不明原发肿瘤的检测有效。
