A prospective study was conducted to compare the accuracy of clinical examination, computed tomography (CT), and positron emission tomography (PET) in identifying head and neck squamous cell carcinoma metastatic to cervical lymph nodes. The findings in the necks of 49 patients evaluated by clinical examination and CT were compared to the findings in the same necks by PET, a newly available metabolic imaging modality. Pathology specimens were available for 45 of the necks. The findings of PET and CT correlated in 84% of cases. In the cases that did not correlate, CT proved correct in four of five cases. PET (82%) and CT (84%) were comparable and were both better than clinical examination (71%) in correctly identifying the presence or absence of metastatic disease.
进行了一项前瞻性研究，以比较临床检查、计算机断层扫描（CT）和正电子发射断层扫描（PET）在识别颈部淋巴结转移的头颈部鳞状细胞癌方面的准确性。将49例通过临床检查和CT评估颈部情况的患者的检查结果，与同一颈部通过PET（一种新可用的代谢成像方式）检查的结果进行比较。45例颈部有病理标本。PET和CT的结果在84%的病例中相关。在不相关的病例中，CT在五分之四的病例中被证明是正确的。在正确识别是否存在转移性疾病方面，PET（82%）和CT（84%）相当，且都优于临床检查（71%）。
