Charles R Joseph, MD Associate Professor of Neurology and Internal Medicine. Graduated from Temple University School of Medicine in 1977. Board-Certified Neurology and Neuroimaging. Have practiced Neurology and have interpreted Neuroimaging studies since 1982. Retired from private practice in 2014 and joined the faculty at Liberty University College of Osteopathic Medicine. Have pioneered the use of ASL MRI determination of glymphatic clearance in the late phase of cerebral perfusion. Have published articles on this approach for use in the early stage of neurodegenerative disease and frank Alzheimer disease demonstrating regional delay in clearance of labeled protons from affected brain regions. In addition, I have demonstrated the utility of this ASL MRI approach in the diagnosis of acute traumatic brain injury. I have received awards at the institution for clinical research and the state of Virginia award for providing volunteer neurologic services for the indigent. My current role as associate professor includes lecturing on topics of Neurology, Nephrology, and Neuroimaging, Course director for Internal Medicine, and continued clinical MRI research.
