Abstract OBJECTIVES: In contrast to lung cancer with ground-glass opacity, the radiological investigation of solid lung cancer has not been well examined. The aim of this study was to explore chest computed tomography (CT) and positron emission tomography (PET)/CT findings with regard to outcomes after lung cancer surgery in order to radiologically classify clinical stage IA lung cancers by tumour aggressiveness. METHODS: Three hundred and fifteen clinical stage IA patients were analysed. Four groups were defined by tumour solidity on CT and by the standardized uptake value (SUV) index on PET–CT (tumour maximum SUV/mean right liver lobe SUV). We analysed the association between radiological findings and both pathological invasiveness and postoperative outcome. RESULTS: Group A (n = 84) had an SUV index
