目的探讨氟代脱氧葡萄糖标记的正电子发射计算机断层扫描(FDG PET-CT)对肺癌骨转移的诊断价值以及其显像特点.方法回顾性分析32例经病理证实的肺癌骨转移FDG PET-CT显像资料,并与CT诊断进行比较.结果 32例115处骨转移病灶FDGPET-CT显像均见明显放射性摄取增高,标准摄取值(SUV)为7.47±3.48;共累及骨骼42块,并发现12例16处隐匿性骨转移.肺癌骨转移易侵及的骨骼依次为肋骨(26处,22.61%)、胸椎(21处,18.26%)、髂骨(18处,15.65%)、腰椎(16处,13.91%)等.CT发现99处病灶,阳性率为86.08%,与FDG PET-CT比较差异具有统计学意义(P＜0.05),FDG PET-CT探测骨转移灶明显优于CT.结论 FDG PET-CT可显示转移灶侵犯部位及范围,并能早期发现肺癌骨转移病灶,在肺癌全身转移的监测方面具有独特的优势.

Objective To investigate the FDG PET-CT image characteristics of bone metastases from lung cancer and the clinical value of 18F-fluorodeoxyglucose(FDG)PET-CT for diagnosis to bone metastases from lung cancer.Methods 32 cases of bone metastasis from lung cancer examined by FDG PET-CT had been studied.All of them were proved by pathology after operation or biopsy.Their FDG PET-CT diagnosis were analyzed by comparing with CT diagnosis. Results All of 115 lesions of 32 cases showed intense uptake of 18F-FDG. SUV mean was 7.47±3.48. 115 lesions located in 42 pieces of bones. Most importantly.16 lesions of occult bone metastases of 12 cases were found.The most related bone were ribs(26/115,22.61%),thoracic vertebral(21/115,18.26%),iliac bone(18/115,15.65%)and lumbar vertebral(16/115,13.91%).96 lesions(83.48%)showed lytic type on CT images,1 lesion(0.87%)showed sclerotic type,and 2 lesions(1.74%)showed mixture type.Conclusion The FDG PET-CT can early detect bone metastases from lung cancer.show their exact location,and have superiority in the screen of bone metastases from lung cancer.
