1. A method for automatic determination of perfusion in a magnetic resonance (MR) system, comprising the steps of: generating multiple first MR data sets from a volume element over time using a perfusion-sensitive imaging sequence; generating multiple second MR data sets of said volume element over time using a control MR imaging sequence; automatically statistically analyzing said first MR data sets and said second MR data sets to obtain a statistical analysis result and, from said statistical analysis result, automatically determining perfusion in said volume element.
