Abstract:
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.
