Profile Headshot


Dr. Ernst Garcon is board certified in diagnostic radiology with subspecialty training in neuroradiology. He is an associate professor of radiology at Columbia University Irving Medical Center and an assistant attending radiologist at NewYork-Presbyterian Hospital. In addition to his clinical responsibilities, he also teaches and supervises radiology residents and medical students.

Dr. Garcon has extensive experience in all aspects of neuroimaging and a clinical focus on non-vascular neurointerventional procedures and neurodegenerative imaging. He is a member of the Radiological Society of North America, American College of Radiology, American Society of Neuroradiology, and the American Society of Spine Radiology.

Dr. Garcon's extensive global health work has led to significant improvements for diagnostic imaging in Haiti. In partnership with several global health foundations and organizations, he helped to develop Haiti's first radiology residency program and is currently assisting with the development and launch of the first radiologic technologist program in the country. He has also organized and provided on-site radiology education for physicians and residents at the State University of Haiti Hospital in Port au Prince and has hosted several externships for Haitian residents at Columbia.

Dr. Garcon is also a member of the Department of Radiology's Diversity Committee, promoting the recruitment and development of minority faculty. His work is focused on inspiring young students with disenfranchised backgrounds who are interested in medicine and wish to pursue a career in radiology.

"Do your work with your whole heart, and you will succeed - there's so little competition."—Elbert Hubbard

Dr. Garcon's primary research interest is quantitative imaging of white matter diseases in late life depression using conventional and advanced MR imaging techniques such as arterial spin labeling (ASL): It is a multidisciplinary work with psychiatrists and neuro psychologists at the New York State Psychiatric Institute to better understand the clinical and imaging characteristics of older individual with late life depression and cognitive decline.

He is also interested in looking at the environmental factors that may trigger depression in older individuals living in the Nother Manhattan area. A multidisciplinary pilot grant proposal was submitted to the Columbia Community Based Participatory Research (CBPR) for looking at the relationship between the built environment and late life depression.

  • Arterial Spin Labeling
  • Quantitative imaging of White Matter Disease

Global Health Activities

Works with the American College of Radiology (ACR) to reopen the radiology residency training at the General Hospital in Port-au-Prince.

Provides Emergency and Neuroradiology teaching to general practitioners and Radiology Residents in Haiti for the past four years through a program named "Radiology Education Days", sponsored by the ACR Foundation.

Works with members of the ACR and ASRT to prepare the curriculum for the first university based school of Radiology technologists. The curriculum has been approved by the Rector of the State University.

CUMC radiology provides CT scan interpretations to the University Hospital in Mirebalais, Haiti managed by Partners In Health.
