Airway, cardiac and pulmonary imaging


Dr. Fleck did his radiology training while in the Navy. He served his final two years in the Navy as the pediatric radiologist at Naval Medical Center San Diego with additional duty as radiology department head on the hospital ship MERCY. Dr. Fleck came to Cincinnati Children’s Hospital Medical Center in November of 2003 to be a general pediatric radiologist and to develop the cardiac magnetic resonance imaging program. Dr. Fleck is currently the section chief for cardiac imaging and continues clinical cardiac imaging and research.

Much of Dr. Fleck’s research focuses on the cardiopulmonary system with NIH grant support to investigate the use of MRI in evaluating cystic fibrosis and a second grant to use MRI data to create a model of airway collapse in sleep apnea.
