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

2012

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 …
