Method for obtaining magnetic resonance image data using a multi-echo MR sequence with improved signal-to-noise ratio of the phase information

In a method and magnetic resonance (MR) system to create an MR magnitude image data set and a phase image data set of an examination subject, first echo signals in a first raw MR data set are detected after a first echo time TE1 and at least second echo signals in at least one second raw MR data set...

More Information
Summary:In a method and magnetic resonance (MR) system to create an MR magnitude image data set and a phase image data set of an examination subject, first echo signals in a first raw MR data set are detected after a first echo time TE1 and at least second echo signals in at least one second raw MR data set are detected after a second echo time TE2 that is longer than TE1, a magnitude image data set is generated on the basis of the first raw MR data set and the at least one second raw MR data set with averaging of the first and the at least one second raw MR data set, and the phase image data set is generated based on the phase information contained in the at least two raw MR data sets, with averaging of the respective phase information contained in the at least two raw MR data sets.
