Sonography and CT were used pre-operatively for lymph node staging in patients with head and neck malignancies. The accuracy of the imaging methods surpassed that of palpation (palpation 85%, CT 85%, sonography 90%). Sensitivity was significantly increased from 74% (palpation) to 84% (CT) and 90% (sonography), ie. there was a reduction in false negative findings. Size of lymph nodes was not closely correlated with metastatic involvement. Reactively enlarged lymph nodes were more easily defined by CT and sonography than by palpation. This reduced the specificity of sonography (90%) and of CT (86%) compared to palpation (94%).
超声检查和CT在术前用于头颈部恶性肿瘤患者的淋巴结分期。这些成像方法的准确性超过了触诊（触诊85%，CT 85%，超声检查90%）。敏感性从74%（触诊）显著提高到84%（CT）和90%（超声检查），即假阴性结果减少。淋巴结大小与转移累及情况无密切相关性。与触诊相比，CT和超声检查更容易界定反应性肿大的淋巴结。与触诊（94%）相比，这降低了超声检查（90%）和CT（86%）的特异性。
