Abstract:
A method for determining a perfusion image of a portion of a body placed in a static magnetic field by means of magnetic resonance (MR) comprising:generating a control pulse sequence in a first portion of the body,measuring a control data set by generation of an MR-image sequence for imaging a third portion of the body to be imaged,generating a labelling pulse sequence in a second portion of the body wherein a fluid flows towards the third portion,measuring a labelled data set by generation of the MR-image sequence for imaging of the third portion of the body,reconstructing the perfusion image of the fluid in the third portion of the body from a combination of the control data set and the labelled data set,wherein the labelling pulse sequence comprises a first selective RF pulse and a second RF pulse, and the control pulse sequence comprises the first selective RF pulse and a third RF pulse, a phase of the second RF pulse being opposite to that of the third RF-pulse.
