[Health economics analysis for 18F-fluorodeoxyglucose positron-emission tomography compared with computed tomography in lung cancer].

Compared with conventional imaging, 18F-fluorodeoxyglucose positron-emission tomography compared with computed tomography (18F-FDG PET/CT) possesses higher sensitivity and specificity in the diagnosis of solitary pulmonary nodule (SPN) and lung cancer. From the perspective of health economics, PET/CT is more suitable strategy for diagnose of SPN with intermediate probability of malignancy, and has good health economics value in preoperative staging diagnosis and follow-up after radiotherapy and chemotherapy of lung cancer. The evaluation method, effect index and comparison method used in the health economics 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 health economics, and in recent years mathematical models are used in most studies.
