摘　　要：目的探讨舌根部恶性肿瘤(舌根癌)的MRI表现及诊断价值。方法回顾性分析2010年1月-2015年5月我院口腔颌面外科收治经手术病理证实的28例舌根癌患者的临床资料,所有病例资料均进行MRI平扫及增强扫描,对病例患者MRI表现进行回顾性分析,以探讨MRI在舌根癌中的诊断价值。结果 MRI显示15例左侧舌根病灶,8例右侧舌根病灶,5例为中侧舌根病灶;舌根癌T分期结果敏感性85.71%较临床分期敏感性64.29%显著高(P<0.05);最大径测量MRI测量值(3.52±0.41)cm与样本测量值(3.45±0.41)cm无显著差异(P>0.05);MRI舌根癌最大径≤2cm时淋巴结转移发生率较最大径>2cm时淋巴结转移率显著低(P<0.05),提示淋巴结转移与MRI上所显示原发灶最大径成正相关。结论 MRI可作为舌根癌中诊断的首选方法,MRI对舌根癌淋巴转移检测有一定意义,临床诊断价值较高。Objective To explore MRI performance of malignant tumor of tongue base （tongue base carcinoma） and diagnostic value.Methods A retrospective analysis of clinical data was carried out in 28 patients with tongue base carcinoma confirmed by operation and pathology treated in surgical oncology of our hospital from January 2010 to May 2015, all clinical data underwent MRI plain scan and enhancement scanning, a retrospective analysis of MRI performance of patients was carried out to explore diagnostic value of MRI in tongue base carcinoma.Results MRI showed that there were 15 cases of left side tongue lesions, 8 cases of right side tongue lesions, 5 cases of middle side tongue lesions; sensibility of tongue base carcinoma T staging results 85.71% was significantly higher than sensibility of clinical stages （64.29%） （P〈0.05）, there was no significant difference in maximum diameter measurement MRI measured value （3.52±0.41）cm and sample measured value [（3.45±0.41）cm] （P〉0.05）, incidence of lymphatic metastasis when MRI tongue base carcinoma maximum diameter ≤2cm was significantly lower than that when maximum diameter 〉2cm （P〈0.05）, which suggested lymphatic metastasis was closely relative to maximum diameter of primary lesion showed in MRI.Conclusion MRI can be preferred method in the diagnosis of tongue base carcinoma, MRI has implications for detecting lymphatic metastasis in tongue base carcinoma, clinical diagnosis value is higher.
