Moderní radiologické zobrazovací metody
NEW RADIOLOGIC IMAGING METHODS IN UROLOGY Imaging methods have made great advance in the last decade. Summary gives an overview of modern technology in CT-imaging: helical CT, multidetector scanning with 3D-reconstructions, CT-urography, CT-angiography, virtual cystoscopy and ureterorenoscopy. The list of applications based on a magnetic resonance imaging (MRI) including a spectroscopy of prostate (MRSI) is further presented. Out of new radionuclide methods are specified MIBG-scintigraphy for precise diagnosis of pheochromocytoma and neuroblastoma, sentinel node lymphoscintigraphy in prostate cancer and positron emission tomography (PET), which is clinically relevant particularly in a detection of residual and recurrent testicular tumours and their bone metastases. The future of radionuclide methods is tracing by monoclonal antibodies such as granulocytes and thrombocytes, which are used for detection of inflammatory foci of unknown origin and early detection of postoperative venous thrombosis. The latest field is a telemedicine with an access to Internet databases and an opportunity of „on-line“ experts consultations unusual or complicated situations. Key words: helical CT, CT-urography, CT-angiography, virtual cystoscopy, virtual ureterorenoscopy, magnetic resonance imaging, prostate spectroscopy, MIBG-scintigraphy, lymphoscintigraphy, monoclonal antibodies labelling, positron emission tomography, telemedicine.
