[THE USEFULNESS OF POSITRON EMISSION TOMOGRAPHY / COMPUTED TOMOGRAPHY IN THE DIAGNOSIS OF METASTASIS IN PATIENTS WITH UROTHELIAL CARCINOMA].

(Purpose) This study examined the usefulness of positron emission tomography (PET) / computed tomography (CT) in the diagnosis of metastasis in patients with urothelial carcinoma. (Materials and methods) The subjects were patients who were newly diagnosed with urothelial carcinoma in our department on whom we performed CT and PET/CT to search for metastasis.
