Change entries to match your patient
Patient's code: Age years
Current or former cigarette smoker? Yes No Years ago stopped smoking? years
Prior lung cancer? Yes No Any cancer within the last five years? Yes No
Diameter (4-30 mm only) mm Extra-thoracic cancer > 5years ago? Yes No
Spiculation ? Yes No Upper lobe lesion? Yes No

Probabilities of malignancy are calculated according to the predictive equations published by Swensen and colleagues in Archives of Internal Medicine 157: 849-55, 1997 and according to the predictive equations published by Gould and colleagues in Chest 131: 383-388, 2007. Followup strategies are from Guidelines for management of small pulmonary nodules detected from CT scan: a statement from the Fleischner Society: McMahon H and colleagues: Radiology 237: 395-400, 2005. See original articles for limitations of each approach.

Influence of PET scan on probability assume a sensitivity of percent and specificity of percent
