In the absence of malignancy elsewhere, small nodules are risk stratified using the Fleischner Society guidelines.
Masses >4 cm are usually malignant.
PET is 96% sensitive for lung nodules >1 cm.
Nodules <2 cm are benign in about 80% of cases.
Features suggesting benignity include:
• Lack of interval growth over 2 years
• Calcification (diffuse, central, popcorn or laminar)
• <15 HU enhancement
