Cost-Effectiveness of Alternative Management Strategies for Patients with Solitary Pulmonary Nodules

Appendix (Figure 1). The square decision node ( ) indicates that computed tomography ( ), observation (watchful waiting), surgery, positron emission tomography with 18-fluorodeoxyglucose ( ), or transthoracic needle biopsy may be selected as the initial diagnostic test. If CT is selected first, the result may be possibly malignant or benign. Observation, surgery, biopsy, or FDG-PET may be the next diagnostic test, depending on the results of CT ( ). If FDG-PET is selected as the first test, results may be positive or negative; CT, observation, surgery, or biopsy may be selected as the next test, depending on results ( ). Observation, surgery, or biopsy may be selected after both CT and FDG-PET have been performed ( ).
