摘要 目的探讨18氟脱氧葡萄糖(18F-FDG)PET/CT显像在软组织肿瘤诊断中的临床应用价值。方法软组织肿瘤患者65例,静脉注射18F-FDG后PET/CT显像。经衰减校正后行目测法和半定量分析法测定病灶的最大标准摄取值(SUVm ax)进行图像分析,并与病理检查结果对照。结果根据病理结果目测法发现局部软组织病灶47例,其中良性5例、恶性42例,淋巴结转移6例、骨转移10例、软组织转移7例、肺转移10例。目测法发现局部病灶的准确性、灵敏性均为100%,诊断转移病灶的准确性、灵敏性、特异性分别为96.9%、100%、95.1%。36.9%的病例根据PET/CT结果改变肿瘤分期。半定量分析对鉴别软组织恶性肿瘤的准确性、灵敏性、特异性分别为85.1%、92.9%和20%。结论在软组织肿瘤诊断中18F-FDG PET/CT显像是一种无创性、高灵敏性的检查,特别是对确定软组织肉瘤的分期。
