Robert David Zimmerman, M.D.

Robert Zimmerman

Dr Zimmerman is an expert in neuroimaging. His particular areas of interest include imaging brain tumors and emergent conditions such as cerebral infarction (stroke) hemorrhage trauma and infection. He has been actively involved in research and clinical applications of new technologies including diffusion imaging, diffusion tensor imaging and perfusion imaging. In addition Dr. Zimmerman is also interested in spine imaging. He is a member of the Executive Committee of both the American Society of Neuroradiology and the American Society of Spine Radiology. He is a leader in Radiology education serving of the Radiology Residency Review Committee.
