目的:研究PET-TC和MRI在鼻咽癌淋巴结转移诊断中的应用,比较两种方法的好坏。方法:回顾性分析我市医院2009年1月至2015年3月在该医院接受治疗的120例鼻咽癌患者的临床资料,所有患者都接受了PET-CT或MRI检查,依据随访结果对淋巴结进行定性评价。结果:在120例接受治疗的患者当中,有45例MRI诊断和PET-CT诊断结果不符合,MRI评价为阳性而PET-CT阴性的40个淋巴结,经再次检查为26个阳性。脑恶性淋巴瘤的临床上现在还未发现特征性表现。肿瘤轮廓不规则且具有浸入的生长特点,MRI和PET-CT对恶性淋巴瘤的定位容易但定性困难。结论:从调查结果中可以明确的知道在对患鼻咽癌淋巴结病人的诊断中,PET-CT较之于MRI具有明显的优势。
Objective: To study the application of PET-TC and MRI in the diagnosis of lymph node metastasis of nasopharyngeal carcinoma and to compare the two methods. Methods: The clinical data of 120 patients with nasopharyngeal carcinoma treated in our hospital from January 2009 to March 2015 in our hospital were retrospectively analyzed. All patients underwent PET-CT or MRI. According to the follow-up results, Qualitative evaluation. Results: Out of the 120 patients treated, there were 45 cases of MRI diagnosis and PET-CT diagnosis of non-compliance, MRI-positive and PET-CT negative 40 lymph nodes, after re-examination of 26 positive. Malignant lymphoma has not yet found a characteristic clinical manifestations. Tumor irregularities and has the characteristics of the growth of immersion, MRI and PET-CT easy to locate malignant lymphoma qualitative but difficult. Conclusions: From the results of the survey, it is clear that PET-CT has a clear advantage over MRI in the diagnosis of patients with lymph node involvement of NPC.
