目的：评价18 F-FDG PET／CT显像中盆腔积液标准摄取值测定对良恶性疾病的鉴别诊断价值。方法回顾性分析18 F-FDG PET／CT全身显像发现盆腔积液并经随访确诊的患者51例，其中恶性疾病40例，良性疾病11例。统计所有患者盆腔积液的最大标准摄取值（SUVmax），分析盆腔积液SUVmax对良恶性疾病的鉴别诊断价值，以约登指数之最大点法确定最佳阈值（截断点）。结果恶性盆腔积液SUVmax为2．25±0．64，良性盆腔积液SUVmax为1．33±0．49，两者比较差异有统计学意义（t＝4．49，P＜0．05）。当SUVmax ＝1．7时，约登指数最大（0．668），以此为阈值鉴别诊断良、恶性疾病的灵敏度为85．0％（34／40），特异性为81．8％（9／11），准确性为84．3％（43／51）。结论全身18 F-FDG PET／CT显像中，盆腔积液SUVmax ＝1．7可作为参考指标，为良、恶性疾病的鉴别诊断提供参考。

Objective To evaluate the diagnostic value of Standardized uptake value(SUV) of 18F-FDG PET/CT in the benign and malignant pelvic effusion.Methods Fifty-one patients with pelvic effusion including 40 malignant cases and 11 benign cases were retro-spectively analysed,who underwent 18F-FDG PET/CT.Maximum standardized uptake value(SUVmax) of 18F-FDG PET/CT were calculated and measured in all pelvic effusion patients,and its diagnostic value was evaluated.The maximum Youden index of point method was used to determine the optimal threshold(Cut-off point).Results The SUVmax was 2.25 ±0.63 in malignant pelvic effusion,and was 1.33 ±0.49 in benign disease(t=4.49,P<0.05).The Jorden index was the largest(0.668) when the SUVmax was 1.7.The sensitivity of the differential diagnosis of benign and malignant was 85.0%(34/40),the specificity was 81.8%(9/11) and the accuracy was 84.3%(43/51).Conclu-sion SUVmax of 18 F-FDG PET/CT =1.7 can be used as a reference index for the differential diagnosis of benign and malignant pelvic effu-sion.
