Dr. Charles Tegeler’s research deals with the use of ultrasound in the prevention and treatment of stroke, cerebrovascular disorders, and concussion, as well as the use of such methods for assessment of cerebrovascular physiology, performance, and function in a variety of other clinical settings. Many of these projects utilize Dynamic Vascular Analysis (DVA), a new method for analyzing transcranial Doppler ultrasound data. Specific activities with DVA include the use of this method in the settings of sports-related concussion, vasospasm following subarachnoid hemorrhage, obstructive sleep apnea, carotid artery stenting, sickle cell disease, shunt-responsive hydrocephalus, hyperbaric oxygen therapy, treatment with a variety of compounds, and implementation of a DVA Core Reading Center. His group also studies peripheral arterial disease in stroke patients, and the use of an electronic stethoscope and neural network to better identify patients with carotid stenosis. He participates in a variety of clinical stroke prevention and treatment trials, and Phase II of the ongoing North Carolina Stroke Registry. Dr. Tegeler holds the McKinney-Avant Chair in Neurosonology, serves as Medical Director for the Neuroultrasound Laboratory, and is Head of the Section on Stroke, Cerebrovascular Disease, and Neurosonology. He also is Director of the Neurovascular Ultrasound Courses in the Center for Medical Ultrasound, the Fellowship in Stoke, Cerebrovascular Disease, and Neurosonology, and the Neurosonology Mini-Fellowship Program. He has served as Fellowship Director/Mentor for 15 Fellows in Stroke, Cerebrovascular Disease, and Neurosonology. Dr. Tegeler will provide oversight to the Neurology Clinical Rotation.
