Target Audience:

The Foundation of the ASNR Symposium 2018 will focus on adding value and improving healthcare in neuroradiology. It will center on how neuroimaging adds value in many subspecialty areas, including brain, spine, head & neck, pediatric and neurointerventional procedures. The target audience will include practicing neuroradiologists, other radiologists charged with interpreting neuroimaging studies, radiology fellows andresidents, neuroscientists interested in the latest advances, and non-radiology colleagues whose practices include neuroimaging. Dedicated topic areas include screening and diagnostic neuroimaging, evidence based neurointerventional treatment, emergency neuroimaging use and usefulness, advanced imaging strategies, and healthcare reform.

  2. Describe Medicare’s efforts to reduce the utilization of same-day brain and sinus computed tomography

How Much Imaging is Critical to Stroke Care? Howard A. Rowley, MD

  1. Describe the utility of various imaging techniques and their appropriateness for evaluating TBI based on current evidence.
  2. Apply data to advise clinical colleagues regarding appropriate imaging for patients TBI via evidence-based clinical imaging protocols.

Head Trauma: Rules of EngagementChristopher Whitlow, MD

  1. Evaluate the practical implications of recent imaging-based trials in acute ischemic stroke
  2. Implement new guidelines and stroke triage protocols in your practice


Syncope and Dizziness: When and How Much to Image? Pamela W. Schaefer, MD

  1. Describe factors that predict a higher yield of neuroimaging following clinical assessment of emergency patients with chief symptoms of dizziness and syncope
  2. Describe the utility of CT, MRI, vascular imaging and perfusion imaging in the evaluation of emergency patients with chief symptoms of dizziness and syncope
