Amethyst Radiotherapy Austria is a radiotherapy center in Vienna, established on the premises of Wiener Privatklinik and close to Vienna University Hospital. It is known for providing cancer treatment within a private-hospital setting that is structured around both local and international referrals. The center offers a dedicated Private Patient and International Referral Treatment Service for many types of cancers, tumors, lymphoma, sarcomas, arthrosis, chronic pain, osteoarthritis, and conditions such as endocrine orbitopathy, Dupuytren’s disease, Ledderhose disease, keloids, and heterotopic ossifications. Its treatment offer includes advanced radiation therapy supported by the Elekta Versa HD linear accelerator. Amethyst also works with Minute Medical in the field of radioligand therapies, including 177Lu-PSMA and 225Ac-PSMA for metastatic prostate cancer. The clinic’s partnerships also include access to complementary services such as radiology, physiotherapy, and radiosurgery through partner organizations. International patients are a core part of its patient base, with services presented for people coming from Austria, Europe, and the rest of the world. The patient-services team supports patients through consultations, examinations, and treatment sessions, while the clinic emphasizes personalized treatment planning. The center presents itself as part of a wider pan-European network of high-tech radiotherapy centers. Its care model combines cancer treatment with multidisciplinary support and coordination for patients traveling to Vienna for treatment. The clinic’s public materials describe it as a leading cancer care center, but the most concrete clinical facts are its Vienna location, international referral service, and use of modern radiation technology. This combination makes it a specialized choice for patients seeking radiotherapy in a private setting with cross-border support.
