Amyloid imaging with (11)C-PIB PET/CT and glucose metabolism with (18)F-FDG PET/CT in a study on cognitive impairment in the clinical setting.

Objective: The objective of this study was to evaluate the contribution of amyloid imaging with (11)C-Pittsburgh compound B ((11)C-PIB) and of glucose metabolism on F-fluorodeoxyglucose ((18)F-FDG) PET/CT to the study of cognitive impairment in the clinical setting.

Patients And Methods: Thirty-four patients (15 male, 19 female) were enrolled in the study. They were classified according to their clinically presented symptoms.

Diagnosis of recurrence and assessment of post-recurrence survival in patients with extracranial non-small cell lung cancer evaluated by 18F-FDG PET/CT.

Unlabelled: The accurate diagnosis of recurrence of non small cell lung cancer (NSCLC) is crucial for the appropriate management of patients with suspicion of recurrence (SOR). We evaluated prospectively in the clinical setting the contribution of FDG PET/CT in patients with SOR of NSCLC in terms of sensitivity, specificity, impact on therapy and on survival.

Methods: Of the 55 patients included in the study, recurrence was confirmed in 37 but, follow up data for survival evaluation was available in 34.
