目的评估氟脱氧葡萄糖(FDG)PET/CT在鉴别伴有远端肺不张的支气管恶性病变和良性支气管狭窄的价值。方法回顾性分析研究84例病人,这些病人先行胸部增强CT,然后进行PET/CT检查和经组织学(n=81)或影像随访(n=3)确诊。2名胸部放射学专家回顾最初的胸部CT并判定支气管病灶的良、恶性。2名核医学医生回顾支气管阻塞区
Objective To assess the value of fluorodeoxyglucose (FDG) PET / CT in the differential diagnosis of bronchial malignant lesions with distal atelectasis and benign bronchial stenosis. Methods A total of 84 patients were retrospectively analyzed. These patients underwent thoracic enhanced CT before PET / CT examination and histological (n = 81) or follow-up imaging (n = 3). Two thoracic radiologists reviewed the original chest CT and judged the bronchial lesion as benign and malignant. Two nuclear medicine doctors review the bronchial obstruction area
