BACKGROUND
This study investigated the clinical significance of F-fluorodeoxyglucose positron emission tomography / computed tomography (F-FDG PET/CT) in identifying the causes of fever of unknown origin (FUO).
METHODS
Patients with a fever who received an F-FDG PET/CT examination were retrospectively selected. The means of the two groups were compared using an independent-samples t-test.
RESULTS
Among the 89 included patients, 66 were diagnosed using F-FDG PET/CT. The sensitivity, specificity and diagnostic accuracy of F-FDG PET/CT for the diagnosis of patients with FUO were 84.5%, 25.8%, and 64.0%, respectively. The detection rates of F-FDG PET/CT for neoplastic diseases, infectious diseases and non-infectious inflammatory diseases were 100%, 61.3%, and 75%, respectively. The difference in C-reactive protein (CRP) levels between the two groups was statistically significant.
CONCLUSIONS
F-FDG PET/CT has great clinical importance in diagnosing and identifying causes of FUO and improves the accuracy of FUO diagnosis when combined with serum CRP levels.
背景
本研究调查了氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（F-FDG PET/CT）在不明原因发热（FUO）病因诊断中的临床意义。
方法
回顾性选取接受F-FDG PET/CT检查的发热患者。采用独立样本t检验比较两组的均值。
结果
纳入的89例患者中，66例通过F-FDG PET/CT确诊。F-FDG PET/CT诊断FUO患者的敏感性、特异性和诊断准确性分别为84.5%、25.8%和64.0%。F-FDG PET/CT对肿瘤性疾病、感染性疾病和非感染性炎症性疾病的检出率分别为100%、61.3%和75%。两组间C反应蛋白（CRP）水平差异有统计学意义。
结论
F-FDG PET/CT在FUO的诊断和病因鉴别中具有重要临床意义，与血清CRP水平联合可提高FUO诊断的准确性。
