目的 探讨18氟-脱氧葡萄糖 (18F-FDG)符合线路单光子发射计算机 断层成像术SPECT/CT显像在肺癌术后 随访中的应用价值。方法 回顾性分析 2014年3月-2015年5月我院收治的56 例行肺癌根治术的肺癌患者的临床资 料，病例患者术后均得到有效随访， 以术后病理结果为金标准，评估1 8 F - FDG符合线路SPECT/CT显像在肺癌术后 随访中的应用价值。结果 残端复发、 残端复发合并转移、单个病灶、多发 转移及胸部未见明显复发转移征象患 者例数分别为14、9、4、13、12；18FFDG符合线路SPECT/CT显像诊断肺癌 术后复发灵敏度为93.18%(41/44)， 特异性为75.00%(9/12)，准确性 为83.93%(47/56)，阳性预测值 为93.18%(41/44)，阴性预测值 75.00%(9/12)。结论 18F-FDG符合线路 SPECT/CT显像在肺癌中诊断有一定应用 价值，对肺癌患者术后随访复发诊断价 值较高，为临床医师制定辅助化疗方案 提供重要参考。

Objective To evaluate the application value of 18F-fluorodeoxyglucose (18FFDG) coincidence single photon emission computed tomography (SPECT/CT) imaging in the follow up after lung cancer operation. Methods The clinical data of 56 patients with lung cancer who underwent radical resection in our hospital between March 2012 and May 2013 were retrospectively analyzed. All cases were effectively followed up after operation. With postoperative pathological results as golden standard, the application value of 18F-FDG coincidence SPECT/CT imaging in follow-up after lung cancer operation was evaluated. Results The number of patients with recurrent residual, recurrent residual complicated with metastatic lesions, single lesion, multiple metastases, without obvious recurrence and metastasis in chest were 14, 9, 4, 13 and 12 respectively. The sensitivity, specificity and accuracy of 18F-FDG coincidence SPECT/CT imaging in the diagnosis of recurrent lung cancer were 93.18% (41/44), 75.00% (9/12) and 83.93% (47/56), respectively. The positive and negative predictive values were 93.18% (41/44) and 75.00% (9/12) respectively. Conclusion 18F-FDG line SPECT/CT imaging is of certain value in the diagnosis of lung cancer, and the value in the diagnosis of follow-up recurrence after operation is high, which provides important references for clinical physicians to develop adjuvant chemotherapy program.
