After completing his medical studies (Erasmus University Rotterdam), Dr. Guenoun knew his passion lay in radiology. He began his radiology training at Erasmus MC, the largest academic medical center in the Netherlands.
After just a year of radiology training, a PhD program beckoned: imaging stem cells—loaded with gadolinium nanoparticles—using MRI and bioluminescence. While traditional radiology is based on the shape and size of abnormalities (morphology), cellular imaging examines disease processes at the cellular level, even before they manifest themselves in shape and size.
Dr. Guenoun specialized in MSK radiology (musculoskeletal system) through a fellowship and several external internships, focusing on ultrasound. Ultrasound is arguably his hobby. After defending his dissertation in 2017, he began working internationally as a radiologist in Cambridge, UK, and subsequently at King’s College Hospital, London. From diagnosing and treating professional footballers from Feyenoord, Excelsior, and Sparta at the EMC back then, to international experience in the United Kingdom, Dr. Guenoun brings a wealth of musculoskeletal knowledge to Acibadem.
