Dinner, Registration and Poster set-up
Sunday, 13 March
07:30 Breakfast
Welcome to Alberta
Christian Beaulieu, Ph.D., University of Alberta, Edmonton, Alberta, Canada

Opening Address
Carlo Pierpaoli, M.D., Ph.D., National Institutes of Health, Bethesda, Maryland, USA
08:15 Opening Presentation:
Survey and current status of research on biophysical issues in diffusion MRI of brain.  Progress since the last workshop in St. Malo.
Jeffrey Joseph Neil, MD,PhD, St. Louis Children's Hospital, St. Louis, MO, US
SESSION 1:  Clinical Applications of Quantitative Diffusion
The aim of this session is to provide clinical "state of the field" talks.  Presentations will describe why diffusion MRI is important for the disease state in question and what useful insight it can yield for understanding the disease or improving the diagnosis.  Additionally, speakers will address the methodological issues involved including discussion of problems and confounding factors, and provide an outlook for the future, indicating where improved techniques would help clinically.
