1. A method for magnetic resonance spectroscopy, comprising the steps of:
operating a magnetic resonance apparatus to implement a chemical shift imaging (CSI) pulse sequence for acquisition of magnetic resonance spectroscopic data from a subject situated in the magnetic resonance apparatus including, in said CSI pulse sequence, activating a phase coding gradient that spatially encodes spectral information detected with said pulse sequence, said phase coding gradient exhibiting at least one first time duration in which said phase coding gradient has a value of 0, and at least one second time duration in which said phase coding gradient has a non-zero value; during said CSI pulse sequence, acquiring magnetic resonance raw data representing spectral information, during each of said at least one first time duration and said at least one second time duration, and entering said raw data into an electronic memory representing raw data space, and repeating said CSI pulse sequence in a plurality of repetitions in order to execute a total number of said repetitions that fill an entirety of said raw data space with said raw data; and in a processor, converting only raw data in said raw data space that were acquired during said at least one first time duration when said phase coding gradient has a value of 0 into non-phase-coded spectral information, and making said non-phase-coded spectral information available from said processor in a form allowing a property of the non-phase-encoded spectral information to be evaluated before completing said total number of repetitions of said CSI pulse sequence. |
