目的研究舌鳞状细胞癌(舌鳞癌)的MRI表现,探讨舌鳞癌颈淋巴结转移的MRI诊断方法。方法24例舌鳞癌患者进行MRI检查,分析其MRI征像,测量舌鳞癌的厚度,并与病理结果进行对照研究。结果MRI对舌鳞癌的累及部位、厚度、范围有较好显示,判断颈淋巴结转移的敏感性为66.7%,特异性为76.9%,准确性为66.7%;舌鳞癌厚度>10mm组的淋巴结转移MRI征像与<5mm、5～10mm组有差异(P<0.05)。结论MRI征像结合舌鳞癌厚度可提高颈淋巴结转移诊断的准确性。
Objective To study the MRI findings of tongue squamous cell carcinoma (tongue squamous cell carcinoma) and to explore the MRI diagnosis of cervical lymph node metastasis of tongue squamous cell carcinoma. Methods Twenty - four patients with tongue squamous cell carcinoma were examined by MRI, MRI features were analyzed, the thickness of tongue squamous cell carcinoma was measured, and the results were compared with the pathological findings. Results MRI showed that the location, thickness and extent of tongue squamous cell carcinoma were well demonstrated. The sensitivity, specificity and accuracy were 66.7%, 76.9% and 66.7%, respectively. The lymph nodes of tongue squamous cell carcinoma> 10mm group Metastatic MRI signs and <5mm, 5 ~ 10mm group differences (P <0.05). Conclusions Magnetic resonance imaging combined with tongue squamous cell carcinoma can improve the diagnostic accuracy of cervical lymph node metastasis.
