Title: Quantifying and improving the quality of 4D flow MRI

Speaker: Cristobal Bertoglio, Bernoulli Institute, University of Groningen

Abstract:

4D flow MRI can provide rich information of the blood dynamics but it is also subject to several imaging artifacts. In this work we present a quick overview of the recent research activities around such topics at the Cardiovascular Mathematics Team, namely:

+ Pressure maps reconstruction methods [1]
+ Quality assessment by checking physical compatibility [2]
+ Dual/Multi VENC reconstruction [3]
