[Why is PET/CT essential in urooncology?]. / Miért kell a PET/CT az uroonkológiában?

The wide use of molecular positron emission tomography/computed tomography (PET/CT) imaging in the tumor diagnostics has been playing an important role recently. The clinical role of hybrid imaging (PET/CT, single photon ECT/CT (SPECT/CT)) is growing continuously due to the simultaneous imaging of anatomy and function. Regarding oncology the role of (18)F-fluorodeoxyglucose ((18)F-FDG) PET is proved in several clinical questions, including urooncology. Urologic cancers are associated with low or slightly significant uptake of FDG, due to their more benign behaviour. However, alternative PET tracers have been developed which show promising clinical results and hopefully, in the near future the combination of different tracers are awaited. Additionally, in the future the use of multiparametric measurements, multitracer techniques, and the multimodal PET/magnetic resonance imaging (PET/MRI) technology is going to have a crucial clinical role.
