Research

Dr. A. Choi’s research in cardiac imaging is multifaceted (including in CMR and echo); he has a particular passion for Cardiac CT techniques that enhance the early detection of coronary atherosclerosis, improve management of complex and structural cardiac disease and reduce radiation exposure.  Dr. Choi is widely published with (or co-author) more than 45 abstracts and publications, including in leading cardiovascular journals such as Journal of the Am. College of Cardiology: Cardiovascular Imaging and Journal of Cardiovascular Computed Tomography.  He has received multiple research awards including the Society of Cardiovascular Computed Tomography Young Investigator Award, Outstanding Academic Researcher Award (Finalist), American College of Cardiology Young Investigator Award Finalist (Regional), and Best Case Award from the Society of Cardiovascular Magnetic Resonance/Euro CMR.  He was part of the expert 2016 national guidelines group on Cardiac CT Acquisition from the SCCT and North Am. Society of Cardiovascular Imaging.  Dr. A. Choi is a frequent peer-reviewer for leading cardiovascular journals.  Dr. A. Choi also maintains a voluntary appointment in the Advanced Cardiovascular Imaging Laboratory at the National Institutes of Health with whom he frequently collaborates.
