为研究CT诊断颈淋巴结转移的病理学基础，应用双盲法对行颈廓清术的22例（26侧）头颈癌患者术前的触诊、病理学、CT扫描特征的相关性进行对比研究。资料显示：26侧中，16侧CT扫描阳性，其中1侧为假阳性；10侧阴性，其中1侧为假阴性。CT扫描的敏感性、特异性、准确率分别为93．8％、90．0％、92．3％。并就头颈部鳞癌转移淋巴结CT影像的诊断标准和相应的病理学特征，以及误诊、漏诊的原因进行讨论。
To study the pathological basis of CT diagnosis of cervical lymph node metastasis, a double-blind method was used to compare the preoperative palpation, pathology, and CT scan characteristics of 22 head and neck cancer patients undergoing neck dissection. The data showed that: Of the 26 sides, 16 were positive for CT scans, of which one was false positive; 10 were negative, and one was false negative. The sensitivity, specificity, and accuracy of CT scans were 93.8%, 90.0%, and 92.3%, respectively. The diagnostic criteria and corresponding pathological features of CT images of metastatic lymph nodes in head and neck squamous cell carcinoma, as well as the causes of misdiagnosis and missed diagnosis were discussed.
