Director of Nuclear Medicine​

Alexis Vrachimis

dct-VhrachimisAl

“Using molecular imaging and theranostics, our aim is to enable treatments tailored to the uniqueness of each patient.”

As Director of the Department of Nuclear Medicine, Associate Professor Dr. Alexis Vrachimis is in charge of its Diagnostic Unit of the Department, as well as of the Radioisotope Application Chamber. He was trained and worked in university clinics in Greece and Germany, and decided to leave a promising academic career and repatriate, so as to assist in the installation of a cyclotron and PET / CT in Cyprus – the first and still the only on the island. It was his vision to see this so very crucial service provided to our fellow citizens, and thus freeing them from the additional financial burden and inconvenience of having to travel abroad for it. Since June 2017, Dr. Vrachimis is a member of the medical team led by Professor Zamboglou, and has already seen tangible results from our dedication to providing high quality services in the relief of cancer patients in Cyprus, especially those services which were not available before.
