摘　　要：目的 评估肺癌胰腺转移瘤的CT表现及FDG代谢程度.方法 对24例经确诊的肺癌胰腺转移瘤病例进行分析.所有患者都接受18F-FDG PET/CT显像,病灶FDG代谢程度增高（SUVmax＞2.5）,则被视为阳性转移灶.结果 24例肺癌胰腺转移瘤中,腺癌10例（41.7％）,鳞癌8例（33.3％）,小细胞癌6例（25％）.16例为单发病灶,7例为多发病灶,1例为弥漫性病灶.病灶SUVmax：3.68 ～ 13.76不等,平均值为7.08,其中SUVmax≤5的5例、5＜SUVmax＜ 10的15例、SUVmax≥10的4例,病灶SUVmax5～10之间发生率与其他区间差异具有统计学意义（P＞0.05）.结论 PET/CT在发现肺癌胰腺转移诊断正确率较高.Objective To evaluate CT manifestations and FDG metabolism in pancreas metastasis of lung cancer patients.Methods 24 lung cancer patients with pancreas metastasis were selected in this study.All patients received 18F-FDG PET/CT imaging.The FDG metabolism level higher than 2.5 was taken as positive metastases.Results There were 10 cases of adenocarcinoma （41.7％）,8 cases of squamous carcinoma （33.3％）,and 6 cases of small cell carcinoma （25％）.16 cases were single lesion,7 cases were multiple lesions,and 1 case was diffuse lesion.Lesions SUVmax ranged from 3.68 to 13.76,with a mean of 7.08.Conclusion PET/CT imaging has a high accuracy in the diagnosis of lung cancer patients.
