The UCSF Department of Radiology and Biomedical Imaging and the UCSF Center for Cerebrovascular Research warmly invite you to attend the 10th annual William L. Young/Allison Raaen Lectureship to be held Sept 16, 2019. Our 2019 Lecturer is Dr. Patrick Turski of the University of Wisconsin. Refreshments will be available prior to the lecture (5 p.m.)


Patrick Turski, MD, FACR
Emeritus Professor of Radiology, Neurological Surgery and Medical Physics
University of Wisconsin School of Medicine and Public Health

About the Presenter: Dr. Patrick Turski is Emeritus Professor of Radiology, Neurological Surgery and Medical Physics at the University of Wisconsin.  He is a Distinguished Investigator of the Academy of Radiology Research and received the Gold Medal from the American Society of Neuroradiology. His NIH funding has supported investigations into the pathophysiology of neurovascular diseases resulting in 160 publications in peer reviewed journals, 22 book chapters and one textbook on Clinical MRA. 

Abstract: Advances in 4D Flow MRI acquisition and reconstruction enable high resolution exams to be obtained in practical imaging times. 4D Flow MRI provides images of vascular morphology and quantitative measurements of blood velocity through dimensions of space and time. Hemodynamic parameters such as flow volume, wall shear stress, streamlines, vessel tracking and pressure gradients can be derived from the velocity data. This presentation will focus on application of these parameters to identify altered AVM hemodynamics and the potential effect on mechanical (WSS)-biological (endothelial cell) interactions.

The Raaen family established this Lectureship to honor those who have contributed significantly to the research of cerebrovascular malformations, and in memory of their daughter, Allison, who died of an AVM rupture in November 2005, and William L. Young, MD, a pioneer researcher in AVM and other vascular malformations, upon his passing in August 2013.
