Dr. Lee Gazourian has devoted his career to advancing population health through his expertise in quantitative imaging and AI technology, as both a researcher and clinician. His research and numerous publications emphasize the importance of incidental findings on chest imaging, such as interstitial lung abnormalities, emphysema, and coronary artery calcification.

His work highlights his commitment to integrating advanced imaging techniques into routine clinical practice through guideline-based programs, which are technology-agnostic and designed to identify high-risk patients and connect them with providers who can alter the trajectory of their disease.

Under his leadership, B4 Symptoms is transforming healthcare through early disease detection and optimized treatment pathways.
