目的探讨 18F FDG PET/CT显像学特征在朗格汉斯细胞组织细胞增生症（LCH）分型及疗效评价中的价值。方法回顾性分析经病理证实的18例朗格汉斯细胞组织细胞增生症患者的18FFDG PET/CT显像资料，分别记录病灶的结构特征及葡萄糖代谢特征。结果9例患者为EGB组，9例患者为LS组。EGB组患者化疗前的SUVmax值（7.4±0.5）明显高于LS组SUVmax（2.4±1.4）。11例患者化疗前后均行PET/CT检查，化疗前SUVmax（4.5±2.7），化疗后SUVmax（1.4±1.1），两组比较（t=5.044，P=0.001＜0.05），差异有统计学意义。结论化疗后SUVmax明显下降，PET/CT全身显像对朗格汉斯细胞组织细胞增生症的分型及化疗疗效评价有重要的作用。

ObjectiveTo explore the radiographic characteristics of PET CT in patients with Langerhans′ cell histiocytosis(LCH). MethodsThe radiographic data of PET CT of 18 patients with LCH were analyzed retrospectively, and structural and glucose metabolic features of the lesions were recorded. ResultsPatients were divided into EGB group or LS group, each included 9 patients. SUVmax of LS group before chemotherapy was obviously higher than that of EGB group (7.4 ±0.5 vs 2.4 ±1.4, P=0.005).Among 18 patients, 11 patients underwent PETCT imaging test both before and after chemotherapy, and their pretreatment SUVmax was significantly higher than that of post treatment(4.5 ±2.7 vs 1.4 ±1.1,P=0.001). ConclusionAfter chemotherapy, SUVmax of patients with LCH greatly decreases. Whole body image of PET/CT plays an important role in the grouping and the chemotherapeutic effectiveness evaluation of LCH.
