Abstract

Computer-implemented method for operating a magnetic resonance device (1) for acquiring spatially resolved magnetic resonance data (7),- wherein a segmented turbo spin echo sequence (12), that comprises multiple subsequences (13-16), is used to acquire the magnetic resonance data (7),- wherein each one of the subsequences (13-16) acquires data for a different segment (34, 35) of a sampled k-space (33),- wherein each subsequence (13-16) comprises multiple pulse trains (17-20), each pulse train (17-20) comprising an excitation pulse (21) preceding multiple refocusing pulses (22, 23), and- wherein the multiple pulse trains (17-20) of the respective subsequence (13-16) use mutually different excitation pulses (21) to acquire data for different spectral bins (24-27) and/or different spatial slices of the magnetic resonance data (7),- wherein a repetition time (28-30), that is defined for the respective subsequence (13-16) as the time between the first excitation pulse (21) within that subsequence (13-16) and the first excitation pulse (21) of the subsequence (13-16) that precedes the respective subsequence (13-16) in the segmented turbo spin echo sequence (12), is different for at least two of the subsequences (13-16).
