目的:探讨18F-FDG PET/MR/CT显像在不明原因发热(fever of unknown origin,FUO)中的诊断价值.
方法:对在2009年至2014年间符合不明原因发热诊断标准的57病例,行18F-FDG PET/MR/CT显像,通过目测法和半定量分析方法对18F-FDG PET/MR/CT的诊断结果进行评价.
结果:57例不明原因发热患者,全部行PET/MR或PET/CT检查后通过手术探查或穿刺活检获得病理诊断,临床诊断而非手术治疗者随访半年以上,其中能明确找到致热源的有43例,包括感染性炎性反应16例,恶性肿瘤12例,非感染性炎性反应8例,其他类型7例,未能发现病因14例.而18F-FDG PET/MR/CT显像诊断真阳性38例,假阳性5例,假阴性3例,真阴性11例.18F-FDG PET/MR/CT的灵敏度93.5％,特异性73.7％;阳性预测值88.4％,阴性预测值78.6％.
结论:18F-FDG PET/MR/CT显像在临床"不明原因发热"的诊疗中具有独特价值.
