The beginnings of Diagnose Zentrum Urania date back to the final stages of World War II, when the general practitioner Dr. Wallner saved a British paratrooper's life. As a token of his gratitude the soldier gave the doctor an old x-ray machine from an abandoned military hospital. Since Wallner had little use for it as a general practitioner, he gave it to his friend, Dr. Karl Rohrbacher. Rohrbacher first opened an x-ray practice in the town of Villach in Carinthia, but moved it to the Franz-Josefs Kai in Vienna two years later. There wasn't a single x-ray practice in the eastern part of Vienna at the time, so patients from Stadlau to Floridsdorf had to come to the offices in the 1st district. As many as 200 hundred patients came to the practice every day by 1948.

Peter Riedl and his mother were also among this large circle of patients. In conversation with Dr. Rohrbacher, Riedl's mother once expressed her wish that her son might run a similar practice some day. This idea became a reality many years later. After studying medicine and completing his training at Vienna General Hospital (AKH), Peter Riedl went on to manage the x-ray department in Ethiopia's largest hospital in Addis Abeba. After returning to Vienna, he asked Dr. Rohrbacher if he could become his successor at DZU, and took over in 1979. 

The range of services has expanded at the same pace as medical-diagnostic advances have been over the last decades: Ultrasound, Computed Tomography and Magnetic Resonance Imaging have transformed diagnostic imaging in a most enduring way.

Dr. Peter Riedl was among the first to make use of these developments. Success increased along with the number of innovations.  His partnership and cooperation with Univ.-Doz. Dr. Lucas Prayer, Dr. Wolfgang Drahanowsky und Univ.-Doz. Dr. Peter Barton, MSc, MBA, all of which are now partners in DZU began in 1991, all of which are now partners in DZU. The practice has been known as the DiagnoseZentrumUrania, DZU since 1995.
