Pre-treatment CT examinations of 333 patients with squamous carcinomas in the head and neck region have been analysed. Two hundred and six patients had lymph-node metastases and lymph-node staging was ascertained. The criteria for metastatic involvement were lymph node size greater than 15 mm. and changes in structure (inhomogeneity, central hypodensity and ring enhancement). CT had a sensitivity of 93% and accuracy of 89%. This was better than palpation (sensitivity 64%, accuracy 72%). CT can be regarded as a reliable basis for treatment planning.
对333例头颈部鳞状癌患者的治疗前CT检查进行了分析。206例患者有淋巴结转移，并确定了淋巴结分期。转移受累的标准是淋巴结大小大于15毫米以及结构改变（不均匀性、中心低密度和环形强化）。CT的敏感性为93%，准确性为89%。这优于触诊（敏感性64%，准确性72%）。CT可被视为治疗计划的可靠依据。
