Description

The aim of this study was to assess the role of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in the identification of occult primary cancers. The study population consisted of 39 consecutive patients with histologically proven metastatic disease or diagnosed by conventional procedures (CT or MRI). PET/CT imaging was performed in all patients 1 hour after administration of 3.75 MBq/kg of fluorodeoxyglucose with a whole-body field of view. PET/CT detected the occult primary cancer in 31 cases (79.4%), showing higher sensitivity than other reports. PET/CT was able to depict more primary tumors, though not significantly, than either of the other imaging modalities. (author)
