摘要
目的评价18F-FDG PET/CT在食管癌分期诊断中的价值。方法对86例病理已明确证实为食管癌的患者进行PET/CT检查,利用18F-FDG在肿瘤病灶及转移灶中的高代谢原理,分析全身各系统病灶放射性摄取的最大标准摄取值(SUVmax),对患者进行准确的诊断分析。结果 PET/CT的分期准确率(88.4%)以及区域淋巴结转移检查的敏感性(63.3%)、特异性(83.8%)均较单纯CT高。结论 18F-FDG PET/CT检查对食道癌患者的临床分期和治疗选择具有重要的指导意义。
Objective To investigate the evaluation of PET/CT in the clinical stages of esophageal carcinoma.Methods 18F-FDG PET/CT was performed in 86 patients with esophageal carcinoma envidenced by pathological findings.Analysing the maxium standard uptake value（SUVmax） of the metastasis from head to food based on that 18F-FDG was high uptaked by malignant metastasis,and Staging esophageal carcinoma accurately.Results The accuracy of PET/CT in staging esophageal carcinoma and the sensitivity（63.3%）,specificity（83.8%） of regional lymph node metastases were higher than those of CT alone.Conclusions The image patterns and characteristics of PET/CT is recommended in staging and treatments options of esophageal carcinoma.
