Transaxial (a) and coronal (b) FDG PET/CT images from a 58-year-old male patient, post-operative pathology confirming IA stage lung adenocarcinoma (LUAD). The patient experienced recurrence 16 months after surgery, with a SUVmax value of 9.50, MTV value of 2.02, TLG value of 11.90, NHOP value of 0.43, and NHOC value of 0.121. Transaxial (c) and coronal (d) FDG PET/CT images of a 70-year-old male patient, post-operative pathology confirming stage IIA lung adenocarcinoma (LUAD). The patient has been followed for 74 months post-surgery without recurrence, with a SUVmax value of 16.30, MTV value of 3.05, TLG value of 30.00, NHOP value of 0.32, and NHOC value of 0.13. The position of the hotspot for FDG uptake is notably shifted towards the margin in image (b). Position of hot spot of FDG uptake is indicated by a red star
