摘要 目的:探讨分析骨肉瘤18F-FDG PET/CT显像的影像学特征及其预后。方法:将我院2016年4月-2017年2月收治的35例骨肉瘤患者作为实验对象,对所有患者实施18F-FDG PET/CT显像检查,分析同机CT扫描图像的影像学特点,使用ROI(感区)技术将患者肿瘤病灶的SUVmax计算出来,分析骨肉瘤18F-FDG PET/CT显像的影响预后因素。结果:18F-FDG PET/CT显像的影像学表现为骨质破坏、肿瘤骨、骨膜三角及软组织肿块;肿瘤骨对18F-FDG PET/CT摄取较低,非瘤骨区域或者是软组织肿块对其摄取显著升高;SUVmax是影响预后的独立因素。结论:18F-FDG PET/CT显像实现了骨肉瘤解剖结构改变及代谢变化优势互补,为骨肉瘤诊断及治疗提供了依据。
