摘要
~(18)F-氟脱氧葡萄糖正电子发射型计算机断层显像(~(18)F-f luorodeoxyglucose positron-emission tomography comparedwith computed tomography,~(18)F-FDG PET-CT,简称PET-CT)用于孤立性肺结节(solitary pulmonary nodule,SPN)及肺癌诊断的敏感性和特异性较常规影像检查显著提高。从卫生经济学角度而言,PET-CT用于恶性肿瘤风险偏中的SPN最具成本效果性,且对于肺癌的术前分期诊断及放射治疗、化学治疗后的随访都具有较好的卫生经济学价值。PET-CT用于肺癌诊疗的卫生经济学研究大多采用的评价方法、效果指标及比较方法分别为成本效果分析、生命年和计算增量成本效果比。病例追踪和随访是早期PET-CT卫生经济学研究的一种手段,而近年来大多数研究所采用的都是模型法。
Compared with conventional imaging, 18 F-fluorodeoxyglucose positron-emission tomography compared with computed tomography(18 F-FDG PET/CT) possesses higher sensitivity and specificity in the diagnosis of solitary pulmonary nodule(SPN) and lung cancer. From the perspective of healtheconomics, PET/CT is more suitable strategy for diagnose of SPN with intermediate probability of malignancy, and has good healtheconomics value in preoperative staging diagnosis and follow-up aft er radiotherapy and chemotherapy of lung cancer. Th e evaluation meth od, effect index and comparison meth od used in the healtheconomics research of PET/CT for lung cancer diagnosis and treatment are cost-effect analysis, life year and incremental cost-effect ratio, respectively. Case tracking and follow-up was a means of early studies on PET/CT healtheconomics, and in recent years mathematical models are used in most studies.
