Flow diagram showing nodule evaluation pathway (modeled using the ACCP guidelines). The first step was to calculate a pre-test probability of cancer using the Brock (or McWilliams) model using clinical and nodule characteristics. Based on this pre-test probability, nodules were classified as low, intermediate, or high probability of cancer. Concordance with evidence-based guidelines resulted in a nodule evaluation pathway that resulted in a green box, otherwise the evaluation was determined to be non-adherent to guidelines. ACCP: American College of Chest Physicians; Pca: Pre-test probability of cancer; PET: Positron emission tomography.
