Timothy James Amrhein
Associate Professor of Radiology
Dr. Amrhein is an Associate Professor in the Department of Radiology at Duke University Medical Center where he also serves as the Director of Spine Intervention. He completed residency training in Diagnostic Radiology at Duke, where he served as chief resident, and stayed to complete a Neuroradiology fellowship.
Current Research Interests
Dr. Amrhein leads a team of spine researchers focusing on Spontaneous Intracranial Hypotension and CT guided pain interventions. He has been first author or a co-author on innumerable peer-reviewed publications and has written multiple book chapters. His work has been published in JAMA Neurology, PLOS Med, Nature: NPJ Digital Medicine, Radiology, American Journal of Radiology, Headache, and the American Journal of Neuroradiology
with features in the popular press ranging from national outlets such as the New York Times
and Reuters
to the local press (WRAL
). Dr. Amrhein’s research has been supported through multiple grants including several highly competitive national foundation awards: the RSNA Research Scholar Grant, ASNR Comparative Effectiveness Award, Spine Intervention Society Research Grant, the American Heart Association Bugher Fellowship, and a Spinal CSF Leak Foundation Grant.
