Ratio between maximum standardized uptake value of N1 lymph nodes and tumor predicts N2 disease in patients with non-small cell lung cancer in 18F-FDG PET-CT scan.OBJECTIVE
 F-18 fluorodeoxyglucose integrated PET-CT scan is commonly used in the work-up of lung cancer to improve preoperative disease stage.  Patients operated on non-small cell lung cancer (NSCLC) with N1 disease by PET-CT scan were included.  There were 51 patients with FDG-PET-CT scan N1 disease.  When SUVmax N1/T ratio on integrated PET-CT scan is equal or superior to 0.46, special attention should be paid on higher probability of N2 disease.
