MRI和CT技术对鼻咽癌T分期中的诊断效果比较

Comparison of MRI and CT Techniques in the Diagnosis of T Staging in Nasopharyngeal Carcinoma

目的比较MRI和CT技术对鼻咽癌T分期中的诊断效果。方法选取我院2010年1月—2016年12月收治的60例鼻咽癌患者作为研究对象,该组患者均经病理学检查且确诊。且均经MRI和CT检查。比较两种影像学诊断技术对鼻咽癌T分期诊断的准确性。结果两种诊断方法对T2、T3分期方面的诊断结果对比,差异无统计学意义(P>0.05)。MRI在T2、T3分期方面的诊断率高于CT,差异有统计学意义(P<0.05)。鼻咽壁、椎前肌的MRI的ACD值均低于正常组织,斜坡的ACD值高于正常组织,差异有统计学意义(P<0.05)。结论 MRI对鼻咽癌T分期的诊断情况优于CT,其能很好地显示原发瘤及其邻近受累结构,具有较高的应用价值。

Objective To compare the diagnostic efficacy of MRI and CT in T staging of nasopharyngeal carcinoma（NPC）. Methods 60 patients with nasopharyngeal carcinoma treated in our hospital from January 2010 to December 2016 were selected as the study subjects. All the patients were examined pathologically and confirmed. All were examined by MRI and CT, to compare the diagnostic accuracy of two imaging diagnostic techniques for T staging of nasopharyngeal carcinoma. Results There was no significant difference in the diagnosis of T2 and T3 staging between the two diagnostic methods（P〉0.05）. The diagnostic rate of MRI in T2 and T3 staging was higher than that in CT, the difference was statistically significant（P〈0.05）. The MRI values of ACD in the nasopharynx wall, the anterior vertebral muscle were lower than those in the normal tissue, the ACD value of the slope was higher than that of the normal tissue and the difference was statistically significant（P〈0.05）. Conclusion MRI is better than CT in the diagnosis of T staging of nasopharyngeal carcinoma. It can show the primary tumor and its adjacent structures.
