摘要 目的探讨18F-脱氧葡萄糖(FDG)hPET/CT显像与99Tcm-亚甲基二膦酸盐(MDP)骨显像诊断骨转移瘤的价值。方法56例确诊的恶性肿瘤患者均于2周内分别行FDG和MDP骨显像,其中35例经手术、活组织病理检查、其他影像检查及随访证实存在骨转移病灶。对2种显像结果进行对比分析。结果35例骨转移患者18F-FDG hPET/CT显像阳性32例,骨显像阳性31例,灵敏度分别为91.4%和88.6%,差异无统计学意义(P>0.05)。21例非骨转移患者中18F-FDG hPET/CT显像阴性19例,骨显像阴性12例,特异性分别为90.5%和57.1%,差异有统计学意义(P<0.05)。2种方法诊断骨转移瘤的准确性分别为91.1%和76.8%,差异有统计学意义(P<0.05)。结论18F-FDG hPET/CT显像与99Tcm-MDP骨显像对骨转移瘤的诊断均有价值,两者灵敏度相当,前者有更高的特异性和准确性。
