Pioneering Cardiologist Honored for Decades of Life-Saving Nuclear Imaging Research

Vasken Dilsizian, MD, has been recognised with two major honours at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2026 Annual Meeting. The awards highlight his decades of groundbreaking work in nuclear cardiology and leadership within the field. His contributions span research, clinical practice, and professional standards, shaping modern cardiac imaging. Dr Dilsizian’s early career saw a key breakthrough in thallium stress imaging. His research on thallium reinjection improved the detection of myocardial ischemia, a condition where blood flow to the heart is reduced. This advancement allowed for more accurate diagnoses and better patient care.

Later, his studies linked myocardial ischemia to cardiac arrest and syncope in young patients with hypertrophic cardiomyopathy. These findings led to better clinical interventions, reducing risks for vulnerable groups. He also played a pivotal role in adapting 18F-fluorodeoxyglucose (FDG) PET/CT imaging to detect infections in left ventricular assist devices (LVADs), a critical tool for patients relying on these life-saving implants.

Beyond research, Dr Dilsizian has worked closely with major organisations. Collaborations with the National Institutes of Health (NIH), American Heart Association, and American College of Cardiology have strengthened clinical guidelines. His efforts in credentialing protocols helped standardise competence in nuclear cardiology, ensuring consistent, high-quality care.

His leadership extended to the SNMMI, where he served as president from 2019 to 2020. During this time, he guided the society through the COVID-19 pandemic and organised its first fully virtual Annual Meeting. Prior accolades include the SNMMI Hermann Blumgart Pioneer Award (2014), the title of 'Master' from the American Society of Nuclear Cardiology (2016), and the Lifetime Achievement Award from the World Federation of Cardiac Imaging and Clinical Cardiology (2019). Currently, he holds the position of professor of radiology and medicine at the University of Maryland School of Medicine in Baltimore. The Minoshima-Pappas Transformational Leadership Award and the Henry N. Wagner, Jr., MD, Lectureship mark the latest recognitions in Dr Dilsizian’s distinguished career. His work continues to influence nuclear cardiology, from advancing imaging techniques to improving patient outcomes. The awards reflect his enduring impact on both research and clinical practice.
