The accuracy of computed tomography (CT) in detecting cervical lymph node metastases was studied. Twenty patients with squamous carcinoma of the head and neck were selected. The results obtained by cervical palpation, CT and postoperative histological study were compared. Palpation had a sensitivity of 64% and specificity of 100%. CT had a sensitivity of 71% and specificity of 100%. The small gain in sensitivity does not justify the systematic use of CT to study cervical lymph nodes in head and neck squamous carcinoma.
研究了计算机断层扫描（CT）检测颈部淋巴结转移的准确性。选取了20例头颈部鳞状细胞癌患者。比较了颈部触诊、CT及术后组织学研究的结果。触诊的敏感性为64%，特异性为100%。CT的敏感性为71%，特异性为100%。敏感性的微小提高并不能证明在头颈部鳞状细胞癌中系统性地使用CT来研究颈部淋巴结是合理的。
