Is 2-deoxy-2-[(18)F]fluoro-D-glucose PET/CT acquisition from the upper thigh to the vertex of skull useful in oncological patients?

Aim:To assess whether performing routinely 2-deoxy-2-[18F]fluoro-D-glucose PET/CT (18FDG PET/CT) scanfrom the upper thigh to the vertex of skull is clinically relevant. Materials and Methods: 3502 (1634 female; mean-age 60+16) consecutive patients undergoing 18 FDG PET/CT were retrospectively analyzed. Patients were divided in 10 groups according to primar y malignancy. Chi-square analysis was used to assess differences among proportions. A p value < 0.05 was considered significant. Results: 18 FDG PET/CT was positive in head district in 130/3502 (3,7%) patients. In all patients lesions were unknown before PET/CT examination. PET/CT showed 158 positive brain/head uptake in the 130 patients.…

18F-FDG PET AND PET/CT IN THE LOCALIZATION AND CHARACTERIZATION OF LESIONS IN PATIENTS WITH OVARIAN CANCER

Aim: The aim was to compare the imaging findings of 18F-fluorodeoxyglucose (18F-FDG) PET and integrated PET/CT in patients with primary, recurrent or metastatic ovarian cancer. Materials and methods. 21 women with ovarian cancer were evaluated. All patients had a integrated PET/CT scan. Localization, infiltration and uptake intensity of [18F]FDG were evaluated on PET and PET/CT. The certainty of localisation and characterisation was scored on a 3 point scale (L1 definite localisation; L2 probable localisation; L3 uncertain localisation; C1 benign; C2 equivocal; C3 malignant). Results. PET scored as L1 54 lesions (44%), as L2 51 (42%), and as L3 17 (14%). On the other hand, PET/CT scored as …
