Dr. Jonathan Weinsaft, an esteemed physician-scientist who focuses on clinical research and cardiovascular imaging, is the chief of the Greenberg Division of Cardiology at Weill Cornell Medicine and NewYork-Presbyterian/Weill Cornell Medical Center. Dr. Jonathan Weinsaft directs the cardiac MRI program and participates in the cardiac CT angiography program at New York Presbyterian Hospital - Weill Cornell. In addition to their active clinical services, both programs are actively engaged several research studies aimed at improving diagnostic techniques as well as clinical risk stratification for patients with atherosclerotic heart disease and congestive heart failure.Dr. Weinsaft is a member of the Division of Cardiology at NY Presbyterian Hospital - Weill Cornell Medical Center, where he is focused on the use of novel non-invasive imaging techniques such as cardiac MRI, cardiac CT, and nuclear cardiac imaging for the identification of coronary artery disease and related manifestations.Dr. Weinsaft completed undergraduate and graduate studies at New York University and subsequently received his medical degree from the New York University School of Medicine. Dr. Weinsaft completed his Internal Medicine residency and Cardiology fellowship at the New York Presbyterian Hospital Weill Cornell Medical Center. He also completed a research fellowship in cardiovascular imaging at Duke University Medical Center, where he was subsequently on faculty prior to being recruited to NY Presbyterian Hospital & Weill Cornell to develop the cardiac MRI program. In addition to serving as the Michael J. Wolk Foundation Clinical Scholar at NYP - Cornell (2005), Dr. Weinsaft has received the American Heart Association's Laennec Society Young Clinician Award (2001), the American Society of Nuclear Cardiology Young Investigator Award (2003), and the Doris Duke Charitable Foundation Clinical Scientist Development Award (2006). Research interests include use of cardiac MRI and CT for identification of ischemic and infarcted myocardium as well as prognostic risk assessment.

Bradley B. Pua, M.D.Chief, Division of Interventional Radiology Director, Lung Cancer Screening Program Director, Radiology Consultation ServicesDr. Bradley Pua is a nationally recognized leader in Interventional Radiology, known for advancing multidisciplinary care, early cancer detection, and procedural innovation. He earned his B.S. in Chemistry from New York University (NYU) and completed his M.D. at NYU School of Medicine. After three years of surgical residency at NYU Medical Center, he trained in Interventional Radiology through a fellowship at NewYork-Presbyterian/Weill Cornell and Memorial Sloan Kettering Cancer Center. He completed his diagnostic radiology residency at Cornell, serving as Chief Resident.Dr. Pua’s clinical practice includes a wide range of image-guided therapies such as embolization, stent placement, tumor ablation, biopsy, and vascular access. His focus areas include pediatric interventions and minimally invasive cancer therapy, with particular expertise in thoracic tumors.He co-founded a multidisciplinary vascular anomalies team that provides coordinated, longitudinal care for patients with hemangiomas, arteriovenous malformations, venous anomalies, and lymphatic disorders.As Director of the Lung Cancer Screening Program, Dr. Pua has streamlined diagnostic and therapeutic pathways for pulmonary nodules, accelerating access to curative treatment. He leads and collaborates on multiple clinical trials focused on minimally invasive lung tumor treatment, utilizing advanced techniques such as radiofrequency, microwave, cryoablation, and pulsed electric field ablation.A champion of emerging technology, Dr. Pua integrates augmented reality (AR) solutions into procedural planning and image-guided interventions. His work explores how AR overlays can enhance precision, safety, and outcomes across interventional oncology and complex vascular treatments.https://www.cbsnews.com/newyork/news/how-2-new-yorkers-are-tipping-the-odds-of-lung-cancer-survival/
