计算机断层扫描 (CT) 评估淋巴结转移的准确性与 28 名已知头颈部鳞状细胞癌且接受颈清扫术的患者的病理检查回顾性相关。 3 名患者接受了双侧颈部淋巴结清扫，总共 31 处淋巴结清扫。CT 扫描对 31 处颈部淋巴结清扫中的 28 处进行了正确分期，在淋巴结转移检测方面的准确度为 90%，敏感性为 87.5%，特异性为 100%。 在21例真阳性中，有7例低估了淋巴结病变的范围。对于囊外淋巴结扩散，CT的准确率为62%，敏感性为62.5%，特异性为60%。 淋巴结转移的所有三种假阴性均发生在转移扩散至颌下淋巴结的情况中。现有的CT评估淋巴结转移的标准敏感且特异，但在评估结外扩散时CT可能无法检测到37.5%的病例。
The accuracy of computed tomography (CT) in the assessment of nodal metastases was correlated retrospectively with the pathological examination in 28 patients with known head and neck squamous cell carcinoma, who underwent neck dissections. Three patients had bilateral neck dissections resulting in a total of 31 dissections.CT scanning correctly staged 28 of 31 neck dissections providing an accuracy of 90%, a sensitivity of 87.5% and a specificity of 100% in the detection of nodal metastases. Of the 21 true positives, underestimation of the extent of nodal disease occurred in seven cases.Regarding extracapsular nodal spread, CT resulted in an accuracy of 62%, a sensitivity of 62.5% and a specificity of 60%. All three false negatives for nodal metastases occurred in metastatic spread to the submandibular nodes.The existing criteria for assessment of nodal metastases with CT are sensitive and specific, but in the assessment of extranodal spread CT may not detect 37.5% of cases.
