摘要目的回顾性分析18F-脱氧葡萄糖正电子发射/计算机体层成像(FDG-PET/CT)和CT对部分实性的T1期非小细胞肺癌(NSCLC)淋巴结分期的诊断准确性和影像学表现。方法对2005年1月—2011年5月期间的160例经病理证实为部分实性的T1期NSCLC进行淋巴结分期。采用FDG-PET/CT和CT评价淋巴结分期诊断的准确性。采用最大标准摄取值(SUVmax)和原发肿瘤的CT表现评估淋巴结转移的特征。结果160例病人中9例(5.6%)有淋巴结转移。
Abstract Objective To analyze the diagnostic accuracy and imaging performance of 18F-FDG PET / CT and CT in the diagnosis of partial solid T1-stage non-small cell lung cancer (NSCLC) lymph node staging . Methods Totally 160 patients with stage T1 NSCLC confirmed by pathology from January 2005 to May 2011 were studied with lymph node staging. FDG-PET / CT and CT were used to evaluate the accuracy of lymph node staging. The characteristics of lymph node metastasis were assessed using the maximum standard uptake (SUVmax) and the CT findings of the primary tumor. Results Of 160 patients, 9 (5.6%) had lymph node metastases.
