摘要
目的:探讨PET-CT融合显像对肿瘤淋巴结转移的诊断价值。方法:回顾对比研究23例恶性肿瘤伴淋巴结肿大患者的PET-CT、CT/MRI及病理资料。结果:PET-CT对肿瘤淋巴结诊断敏感性和准确度分别为93.7%和86.9%,CT诊断的敏感性和准确度分别为62.5%和69.6%。结论:PET-CT融合显像对肿瘤伴淋巴结肿大是否为癌转移有诊断价值,明显优于CT/MRI,可作为手术或放疗的重要依据,也是肿瘤临床分期的重要依据。
Objective： To explore the diagnostic value of 18 F- FDG PET- CT in the detection of lymph nodes metastasis. Method： according to the pathological result, the data of CT, PET- CT of 23 patients with lymph nodes metastasis were analyzed retrospecitively. Result： The sensitivity, and accuracy of CT and PET- CT in detection lymph nodes metastasis were （62.5%, 69.6%, 93.7%, 86.9% ）. Conclusion： F- FDG PET- CT is better than CT alone for the detection of lymph nodes metastiasis, It may be served as the indication of lymph nodes dissection and irradation therapy, or so it is a key evidence of tumor clinical stage.
