摘要
通过对２２例（２６侧）头颈癌患者颈廓清术前触诊、颈清扫标本病理所见、ＣＴ扫描特征的相关对比研究，探讨ＣＴ对颈淋巴结转移的诊断意义。结果显示ＣＴ对头颈癌颈淋巴结转移的诊断有一定的价值。可提高颈淋巴结转移诊断的准确性、敏感性及Ｎ分期的符合率。但由于诊断者的经验、影像技术限制等因素的影响，ＣＴ诊断仍有其局限性。
Abstract A series of 22 patients with squamous cell carcinoma of the head and neck(SCHN),who undergone neck dissections,had their CT scans examined.Four patients had bilateral neck dissections,therefore providing pathology on 26 dissection samples in total.With patho-logic findings as the standard,sensitivity,specificity and accuracy of palpation is 62.5%,80.0%and 69.2%,Sensitivity,specificity and accuracv of CT in the detection of nodal dis-ease is 93.8%, 90.0%and 92.3%,and the accuracy of the CT scan was significantly greater than the accuracy of palpation(P<0.05).This study indicated that CT is valuable in detecting cervical lymph node metastases from SCHN. But CT scanning was limited by technique and experience of radiologist.
