摘要 目的探讨^(18)F-氟代氧葡萄糖正电子发射计算机断层扫描显像(^(18)F-FDG PET/CT)对患儿神经母细胞瘤骨转移的诊断价值。方法回顾性选取2018年6月—2021年6月该院收治的65例患儿神经母细胞瘤患儿,所有患儿均行^(18)F-FDG PET/CT、^(99)锝代亚甲基二膦酸盐(^(99)mTc-MDP)全身骨显像检查,观察比较两种检查方法的骨转移诊断准确性,并分析^(18)F-FDG PET/CT检查最大标准摄取值(SUVmax)、代谢体积(MTV)及糖酵解总量(TLG)参数对骨转移的诊断价值。结果65例患儿临床诊断为骨转移的患儿39例,^(18)F-FDG PET/CT检出38例(58.46%),准确度为89.23%,灵敏度为89.74%,特异度为88.46%,阳性预测值为92.11%,^(99)mTc-MDP全身骨显像检出41例(63.08%),准确度为87.69%,灵敏度为92.31%,特异度为80.77%,阳性预测值为87.80%;39例患儿骨转移部位分别为四肢长骨干骺端15例、骨盆8例、脊柱8例、颅骨4例、肋骨2例、肩胛骨1例及胸骨1例,溶骨性骨转移61.54%明显高于成骨性、混合型、无变化,溶骨性及混合型骨转移SUVmax值明显高于成骨性、无变化骨转移(P<0.05);骨转移组患儿的SUVmax、TLG及MTV明显高于未骨转移组(P<0.05);ROC曲线分析显示,SUVmax、TLG及MTV诊断骨转移的AUC分别为0.846、0.893及0.927,灵敏度和特异度分别为(61.5%,100%)、(82.1%,88.5%)及(87.2%,92.3%)。结论^(18)F-FDG PET/CT诊断神经母细胞瘤患者发生骨转移具有较高的诊断价值,可通过SUVmax、TLG及MTV参数对患儿骨转移进行诊断。
