鼻咽癌的MRI表现(附78例分析)

MRI diagnosis of original nasopharyneal carcinoma(analysis of 78 cases)

目的 :探讨初诊鼻咽癌的MRI表现及分期诊断要点 ,提高鼻咽癌MRI诊断水平。方法 :回顾性分析 78例初诊鼻咽癌患者MRI表现及分期。MRI扫描序列包括 :轴位T1W /SE及T2 W/TSE ,冠状位SPIR ,Gd DTPA增强后三维扫描。结果 :按 1997年UICC和AJCC联合提出的鼻咽癌TNM分期 ,78例鼻咽癌患者分期为 :0期 1例 ,Ⅰ期 6例 ,ⅡA期 1例 ,ⅡB期 2 4例 ,Ⅲ期 2 3例 ,ⅣA 2 1例 ,ⅣB 2例 ;综合分期属早期 (0～ⅡA期 )的患者仅 8例 (10 .3% ) ,而中晚期 (ⅡB及以上 )患者 70例 (89.7% )。结论 :初次就诊鼻咽癌患者即大部分为中晚期 ,而MRI检查可清晰显示鼻咽癌侵犯范围及淋巴结转移 ,为鼻咽癌的分期、进一步治疗及其疗效观察提供客观依据。

Objective:To study MRI features and staging of original nasopharyneal carcinoma(NPC).Methods:Retrospective study of MRI findings in 78 cases of original nasopharyneal carcinoma was performed.Results:Based on the TNM staging way of UICC and AJCC(1997) in NPC, among 78 patients of nasopharyneal carcinoma: 1 case, stage 0; 6 cases, stage Ⅰ; 1 cases, stage ⅡA; 24 cases, stage ⅡB; 23 cases, stage Ⅲ; 21 cases, stage ⅣA; 2 cases, stage ⅣB.Conclusion:Most patients of original NPC are late!staging, and MR imaging can well demonstrate the size ,extension and lymphadenvarix of the nasopharyneal carcinoma, so it should be reganded as a valuable mean for the patients with original NPC.
