Method for determining magnetic resonance data

A method for determining magnetic resonance data of an examination object in a magnetic resonance facility, comprising:

• determining a first readout gradient field in such a way that a distortion caused by a non-linearity of the first readout gradient field and a distortion caused by a B0 field inhomogeneity are essentially cancelled at a first location of a field of view of the magnetic resonance facility;
• determining a second readout gradient field in such a way that a distortion caused by a non-linearity of the second readout gradient field and a distortion caused by a B0 field inhomogeneity are essentially cancelled at a second location of the field of view, the second location being different than the first location;
• and
• performing a combined spin echo/gradient echo sequence, wherein first magnetic resonance data of a first spin echo is captured using the determined first readout gradient field after a 180° pulse of the spin echo sequence, and second magnetic resonance data is then captured using the determined second readout gradient field.

A magnetic resonance facility, comprising:

• a basic field magnet;
• a gradient field system;
• a high-frequency antenna;
• and
• a control device configured to activate the gradient field system and the high-frequency antenna, configured to receive measurement signals picked by the high-frequency antenna, configured to evaluate the measurement signals, and configured to produce magnetic resonance recordings, the control device being further configured
• to determine a first readout gradient field in such a way that a distortion caused by a non-linearity of the first readout gradient field and a distortion caused by a B0 field inhomogeneity are essentially cancelled at a first location of a field of view of the magnetic resonance facility,
• to determine a second readout gradient field in such a way that a distortion caused by a non-linearity of the second readout gradient field and a distortion caused by a B0 field inhomogeneity are essentially cancelled at a second location of the field of view, the second location being different than the first location, and
• to perform a multiecho sequence, wherein first magnetic resonance data is captured using the determined first readout gradient field after a 180° pulse and second magnetic resonance data is captured using the determined second readout gradient field after a further 180° pulse.
