The invention relates to a magnetic resonance method for determining a perfusion image of a portion, which method comprises the following steps: generation of a control pulse sequence in a first portion of the body and measurement of a control data set by generation of an MR-image sequence for imaging of an third portion of the body, generation of a labelling pulse sequence in a second portion of the body wherein a fluid flows towards the third portion, and measurement of the labelled data set by generation of the MR-image sequence for imaging the third portion of the body, and reconstruction of the perfusion image of the fluid in a mass of the third portion of the body from a combination of the control data set and the labelled data set. In order to reduce the geometric restrictions and compensate magnetic transfer effects, the labelling pulse sequence comprises a first selective RF pulse and a second RF pulse, 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.
