The Maximum Standardized FDG Uptake on PET/CT in Evaluation of Patients with Non-small Cell Lung Cancer: A Prospective Study

Background: Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (FDG-PET/CT) functional imaging has shown to be an invaluable non-invasive, diagnostic method, enhancing the accuracy in presenting of Non-Small Cell Lung Cancer (NSCLC). The purpose this research was evaluate role maximum standardized uptake value (SUV max) PET-CT staging and follow-up operable non-operable patients with NSCLC.
 Methods: This prospective carried on 50 cases histopathological diagnosis NSCLC were mentioned do PET/CT scanning for initial disease (17 died, 28 survived, five lost so out came after treatment surgery, radiotherapy, or chemotherapy). All underwent intravenous contrast media, 18F-FDG Dosage Administration, CT Technique, PET Fusion, Interpretation.
 Results: SUV max is a semi-quantitative technique determining by tumor cells. Adenocarcinomas have lower measurements compared squamous cell carcinoma. average SUVs tumours ≥ 4 significant increased those < 4, additional analysis showed that significantly correlated size. prognostic factor T N stages as T1 lesions had decrease T2 mean than T3/T4 lesions, also we found N0 NI, NII, NIII. There strong association among ΔSUV Δ size.
 Conclusion: FDG-PET/CT valuable, efficient, reliable method lung cancer cases, lately became portion international standards bronchogenic
