摘要
目的探讨葡萄糖代谢显像PET/CT(^(18)F-FDG PET/CT)在不明原因发热(fever of unknown origin,FUO)中的显像特点及临床应用价值。方法回顾性分析2006年3月至2013年3月63例FUO患者,分析其PET/CT表现图像及病因,最终结果与病理对照或进行随访证实。结果纳入本研究共63例FUO患者,行^(18)F-FDG PET/CT检查后找到发热病因59例,其中良性病变42例,恶性病变17例;未明确病因4例。最终确诊发热病因的59例FUO患者中^(18)F-FDG PET/CT检查诊断真阳性40例,假阳性8例,真阴性1例,假阴性10例。灵敏度80.0%,特异性11.1%。结论在常规方法难以明确诊断FUO病因时,^(18)F-FDG PET/CT检查可为临床进一步诊断提供重要的参考价值。
Objective To research the characteristics and evaluate the clinical application value of 18F-FDG PET/CT imaging for fever of unknown origin （FUO）. Method Sixty-three cases of patients with FUO receiving 18F-FDG PET/CT imaging from March 2006 to March 2013 were reviewed.Analysis was conducted on the characteristics of 18F-FDG PET/CT images,and its result was compared with the pathology report or analysed following a clinical follow-up.Result Among the 63 patients receiving 18F-FDG PET/CT imaging, the etiology of the disease was defined in 59 cases including 42 cases of benign lesions and 17 cases of malignant change,while 4 cases remained uncertain. Compared with the final diagnosis,40 were true positive, 8 false positive, 1 true negative and 10 false negative.The sensitivity is 80.0%, and the specificity is 11.1%.Conclusion In patients with FUO,18F-FDG PET/CT imaging can provide an important reference for the further diagnosis of the disease.
