摘要： 目的 探讨 18F-FDG PET/CT与高分辨率 CT(HRCT)同机联合扫描在肺癌诊断中的应用价值及影响因素。方法 对 50例未能提供HRCT原始数据且临床高度怀疑肺癌、肺癌术后以及肺癌转移的患者进行 18F-FDG PET/CT与HRCT同机联合扫描，分析两者联合应用的临床诊断价值及影响因素。结果 50例患者经过检查前准备、注射、上机前休息及呼吸训练后，PET/CT全部扫描成功(100%)；PET/CT联合HRCT成功46例(92%)，HRCT扫描失败4例(8%)。共35例发现恶性病灶，21例伴有转移；肺癌术后6例伴转移4例；肺部考虑良性结节病变9例，需继续观察。结论 PET/CT与高分辨率CT同机联合扫描技术在肺癌的诊断中具有较高的价值，诊断的准确率、灵敏度较高，是一项无创的、可以观察全身转移情况的影像检查新技术。

Abstract: Objective To explore the application of 18F-FDG PET/CT combined with high-resolution CT (HRCT) in the same scanner on diagnosis of lung cancer, and its influencing factors. Methods 50 patients, in which some cannot supply HRCT raw date and under highly suspicion of being lung cancer, some were postoperative lung cancer and metastasis of lung cancer, were examined by 18F-FDG PET/CT combined with HRCT in the same scanner. Results 50 patients were all successful (100%) on PET/CT scans after preparation, injection, rest and breathing exercises; 46 cases (92%) were successful on PET/CT combined with HRCT scans; 4 cases (8%) failed on HRCT scans. Malignant lesions were found in 35 cases, with the metastasis of 21 cases; 4 in 6 cases of postoperative lung cancer were found metastasis; 9 cases of benign pulmonary nodules need to be observed sequentially. Conclusion 18F-FDG PET/CT combined with HRCT in the same scanner is valuable on diagnosis of lung cancer. The diagnostic accuracy and sensitivity significantly increase. It is a non-invasive new imaging technology and systemic metastasis can be observed.
