Abstract
Urothelial carcinomas need complex approach during staging, because of they may be typically multi-focal, locally aggressive behavior and potential remote dissemination. The possibilities of complex imaging cover MDCT, MRI and 18F-FDG-PET/CT.
In the assessment of the tumors, it is most important to distinguish the invasive spread of the tumor to the surrounding fatty tissue or into renal parenchyma or into neighboring organs respectively. Local invasion could be evaluated by MDCT or MRI with the relatively high accuracy. 18F-FDG-PET/CT is the optimal method able to search on the remote metastases.
It offers depiction of the metastases in lymph nodes, in the skeleton, liver or lung parenchyma. The advantages of three-dimensional modeling are used in the pre-operative assessment of the renal vasculature or urotract.
