Method for Operating a Magnetic Resonance Device, Magnetic Resonance Device, Computer Program and Storage Medium

A magnetic resonance device, comprising:

• a main magnet configured to generate a main magnetic field;
• a gradient coil assembly;
• a radio frequency (RF) coil assembly;
• and
• control circuitry configured to control the gradient coil assembly and the RF coil assembly to cause the magnetic resonance device to acquire spatially-resolved magnetic resonance data by:
• applying a segmented turbo spin echo sequence that comprises multiple subsequences to acquire the magnetic resonance data;
• and
• acquiring, via each one of the multiple subsequences, data for a different respective segment of a sampled k-space, wherein:
• each one of the multiple subsequences further comprises multiple pulse trains, each pulse train comprising an excitation pulse preceding multiple refocusing pulses,
• each one of the multiple pulse trains of each respective subsequence uses respective excitation pulses that are mutually different for acquiring data for different spectral bins and/or different spatial slices of the magnetic resonance data, and
• a repetition time that is defined for the respective one of the multiple subsequences as the time between (i) the first excitation pulse within that subsequence, and (ii) the first excitation pulse of the subsequence that precedes the respective one of the multiple subsequences in the segmented turbo spin echo sequence, is different for at least two of the subsequences.

A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by control circuitry of a magnetic resonance device, cause the magnetic resonance device to acquire spatially-resolved magnetic resonance data by:

• applying a segmented turbo spin echo sequence that comprises multiple subsequences to acquire the magnetic resonance data;
• and
• acquiring, via each one of the multiple subsequences, data for a different respective segment of a sampled k-space, wherein:
• each one of the multiple subsequences further comprises multiple pulse trains, each pulse train comprising an excitation pulse preceding multiple refocusing pulses,
• each one of the multiple pulse trains of each respective subsequence uses respective excitation pulses that are mutually different for acquiring data for different spectral bins and/or different spatial slices of the magnetic resonance data, and
• a repetition time that is defined for the respective one of the multiple subsequences as the time between (i) the first excitation pulse within that subsequence, and (ii) the first excitation pulse of the subsequence that precedes the respective one of the multiple subsequences in the segmented turbo spin echo sequence, is different for at least two of the subsequences.
