Nuclear Medicine


The Nuclear Medicine Team is staffed with Radiology Technicians/ Radiographers, Radiochemists and Medical Physicists. It’s headed by Professor Dr. Alexis Vrachimis who is assisted by Nuclear Medicine Physician Dr. Ioannis Tsechelidis.


The PET/CT Department is equipped with the General Electric IQ Discovery scanner, which is a hybrid imaging scanner that combines positron emission tomography and a 16-slices computed tomographer (CT).

The combination of these two entities, as well as the IQ technology of the PET, provide higher sensitivity and therefore image of better quality in shorter imaging time, lower radiation dose and the capability of whole-body imaging.

The Medical Radiation Technologists are graduates of Greek and Cypriot Universities, and they are well trained to provide the best possible services, with safety and always with respect to our patients.


Radiopharmaceuticals are substances which are taken up by specific organs, tissues and molecular targets. They are used in nuclear medicine as radioactive tracers in medical imaging, and as therapy for a various of medical conditions.

The radiochemist’s role in nuclear medicine is to produce radiopharmaceuticals and perform the necessary quality-checks according to international standards. These radiopharmaceuticals will be used in diagnosis or treatment of the disease. We produce a plethora of radiopharmaceuticals in our facilities, with 18-Fluorine as their main radioactive isotope.

This is done using a machine called cyclotron, which allows us to achieve the production of the above-mentioned isotope, which is then used for the radiosynthesis of the final product that will be administered to the patient. Because of the very short half-life of radiopharmaceuticals, it is essential that standard procedures are applied, so as to achieve the highest possible quality.

Our Radiochemists are Andreas Fesas and Dr. Mohammad-Reza Pourkhessalian.


In the highly specialized field of Nuclear Medicine, Medical Physicists work closely with other health professionals, such as doctors, radiochemists, technologists and nurses and play an important role in the creation, design and implementation of diagnostic and therapeutic procedures for patients. In addition, Medical physic experts are responsible for checking the specifications and ensuring the quality of the specialized equipment used in the department, in order to ensure that the equipment works efficiently, in maximum performance and with patient safety.

One of the most important responsibilities of a Medical Physicist in the clinical field is the radiation protection of patients, the public and of the staff. Medical Physicists provide their science to ensure and enhance the optimal use of the department’s equipment and are responsible together with the rest of the staff for the proper work in radiotherapy and diagnostic and to control the radiation levels.

Finally, but equally importantly, medical physicists undertake the information and training of the Centre’s staff about the risks and benefits of radiation, conducting seminars on radiation protection and medical physics.
