PURPOSE
To compare computed tomography (CT) and magnetic resonance (MR) imaging for the detection of extranodal neoplastic spread (ENS) in metastatic cervical nodes from head and neck squamous cell carcinoma.
MATERIALS AND METHODS
17 patients with a squamous cell carcinoma of the head and neck underwent CT and MR imaging. The neck nodes were assessed for ENS and the results compared using pathology from the surgical resection.
RESULTS
Radiologic-pathologic correlation was performed in 51 malignant nodes. The accuracy, sensitivity and specificity were respectively 73, 65, 93% for CT, and 80, 78, 86% for MR imaging. Comparison of CT and MR imaging showed that there was no significant difference between the two modalities for either sensitivity (P = 0.1317) or specificity (P = 0.3173).
CONCLUSION
CT and MR imaging are comparable for the detection of ENS.
目的
比较计算机断层扫描（CT）和磁共振成像（MR）在检测头颈部鳞状细胞癌转移性颈淋巴结结外肿瘤扩散（ENS）方面的效果。
材料与方法
17名头颈部鳞状细胞癌患者接受了CT和MR成像检查。对颈部淋巴结进行ENS评估，并将结果与手术切除的病理结果进行比较。
结果
对51个恶性淋巴结进行了放射学-病理学相关性分析。CT的准确性、敏感性和特异性分别为73%、65%、93%，MR成像的准确性、敏感性和特异性分别为80%、78%、86%。CT和MR成像的比较显示，两种检查方式在敏感性（P = 0.1317）或特异性（P = 0.3173）方面均无显著差异。
结论
CT和MR成像在检测ENS方面具有可比性。
