目的:通过与术后病理对照,分析舌鳞状细胞癌颈淋巴结转移MRI征象及客观诊断指标,探讨MRI在诊断舌鳞状细胞癌颈部淋巴结转移中的临床价值。方法:对36例舌鳞状细胞癌患者共计115个淋巴结进行MRI术后病理对照分析。结果:舌鳞状细胞癌颈部转移淋巴结在MRI上多数存在微观的淋巴结受侵润征象。舌鳞状细胞癌转移与非转移淋巴结横径差异有统计学意义,但两者T2信号强度差异无统计学意义。结论:MRI可在术前为舌鳞状细胞癌患者提供有效信息,常规MRI图像上肿大淋巴结横短径可作为诊断受到侵润的一个参考指标。
OBJECTIVE: To analyze MRI signs and objective diagnostic indicators of cervical lymph node metastasis of tongue squamous cell carcinoma by pathological comparison with postoperative pathology, and to explore the clinical value of MRI in the diagnosis of cervical lymph node metastasis of tongue squamous cell carcinoma. Methods: A total of 115 lymph nodes from 36 patients with tongue squamous cell carcinoma were analyzed by MRI. Results: Most of cervical lymph node metastases in cervical squamous cell carcinoma had microscopic lymph node involvement on MRI. There were significant differences in the diameter of metastatic tongue and non-metastatic lymph nodes between tongue squamous cell carcinoma and tongue squamous cell carcinoma, but there was no significant difference in T2 signal intensity between them. Conclusion: MRI can provide effective information for patients with tongue squamous cell carcinoma before operation, and the transverse diameter of enlarged lymph nodes on conventional MRI images can be used as a reference index to diagnose invasion of tongue squamous cell carcinoma.
