Indeterminate lung nodules (6-15mm) are frequent findings in patients undergoing chest CT scanning, but adequate follow-up imaging is currently not in place to facilitate early detection, diagnosis and decision making regarding treatment. The introduction of long Field-Of-View PET/CT scanners could make a difference in this matter due to the substantial increase in sensitivity allowing optimal image quality. Whether this new technology could provide improved detection and follow-up of indeterminate lung nodules is what we aim to explore in this study.
