Abstract
In a magnetic resonance spectroscopy method, an excitation RF pulse is emitted with simultaneous emission of a first gradient during an excitation segment having a time duration corresponding to a transmission duration of the excitation RF pulse, a first refocusing RF pulse is emitted that has a first phase with respect to the excitation RF pulse with simultaneous emission of a second gradient during a first refocusing segment that temporally immediately follows the excitation segment and has a time duration corresponding to a transmission duration of the first refocusing RF pulse, an intermediate segment is allowed to elapse immediately temporally following the first refocusing segment for, among other things, temporal positioning of a secondary spin echo, a second refocusing RF pulse is emitted that has a second phase with respect to the excitation RF pulse, with simultaneous emission of a third gradient during a second refocusing segment immediately temporally following the intermediate segment and having a time duration corresponding to a transmission duration of the second refocusing RF pulse, the secondary spin echo is acquired during an acquisition segment immediately tempor…
