To perform multi-slice multi-echo abdominal imaging during free breathing a radial golden angle self-gating technique was used applying 1D projection navigators in an automatically added slice. 1D navigators were utilized to generate a breathing trigger signal through correlation analysis. Since each time point of the trigger signal is directly related to a radial readout in all slices, respiratory phases could be excluded from image reconstruction for obtaining breathing corrected images. Image blurring caused by respiratory motion was highly reduced.
