The SDTS conducts clinical research at the Stroke Centers of Suburban Hospital in Bethesda, MD and the MedStar Washington Hospital Center in Washington, D.C., where the NINDS has placed stroke teams and magnetic research imaging (MRI) research facilities.

The section's research efforts pioneered the routine clinical use of diffusion and perfusion MRI in ischemic stroke, performed seminal studies defining the human ischemic penumbra with MRI, and introduced innovative uses of MRI into stroke clinical trial design. The section's current research focus is on novel diagnostic and therapeutic approaches to acute brain injury: acute ischemic stroke, blood-brain barrier disruption, white matter disease and traumatic brain injury.  A major research interest of the section is to delineate biomarkers for drug development to treat and/or prevent stroke.
