| 摘 要： | 目的：确定磁共振（MRI）诊断口腔癌的颈淋巴结隐匿性的效果。方法：41例临床触诊检查颈部淋巴结转移阴性的头颈部恶性肿瘤病人，术前行MRI颈部扫描，了解颈淋巴结转移阳性和阴性的情况，并在术后同病理诊断对照。结果：41例病人被手术切除的颈淋巴清扫标本内有12例经病理证实为颈淋巴结转移，其中MRI发现9例，其敏感性为75％，特异性为87％，3列假阴性，主要是转移的淋巴结体积小，形态无明显的变化，其内部信号变化不明显，结论：MRI技术可作为临床诊断颈淋巴结隐匿性转移的有效手段之一。

| Abstract: | Objective To detect the occult cervical metastasis with MRI so as to find out its diagnostic accurate rate . Methods 41 lateral necks(negative by clinical palpation) with malignant tumor of head and neck were examined by MRI before operation and correlated with postoperative pathologic finding. Results With MRI evaluation occult cervical metastasis has higher accurate rate(75%), nine of 12 lateral metastatic positive necks were detected on MRI, other three false nagative necks were not found, owing to no change of the shape of the metastatic nodes. Conclusion At present, MRI is one of the effective methods evaluating occult cervical metastasis with malignant tumor of head and neck, but it has still a certain limitation. [ |
