Target Audience:

The Foundation of the ASNR Symposium 2017 will focus on Discovery and Didactics featuring “What's New?” for neuroradiologists. It will focus on the role of neuroimaging in defining CNS disease mechanisms and how to best prepare for change, including “What's Next?” in training, teaching and leading the process of lifelong learning. The target audience will include practicing neuroradiologists, other radiologists charged with interpreting urgent CNS and head and neck studies, neuroscientists interested in the latest advances, clinical colleagues ordering CT and MRI in an emergency setting, and trainees. Dedicated topic areas include what's new in Head and Neck Techniques and Pediatric Neuroimaging, Metallic Artifact Reduction MR Sequences (MARS), Imaging Debate session on fMRI: Fact, Fiction and Future, Overnight Coverage Alternatives, Neuroimaging for Functional Neurosurgery, Cerebrovascular Treatment and Training, Wellness and Burnout in Practice and Training, Machine Learning and Artificial Intelligence.
