Method and apparatus for acquiring magnetic resonance data from a target region while the target region moves due to respiration

摘要

In a method for recording magnetic resonance data in a target region of a patient while the target region moves due to respiration a single-shot turbo spin echo sequence is used as a magnetic resonance sequence in a magnetic resonance apparatus. SPAIR fat saturation is used by emitting an inversion pulse at an inversion time before the data recording with the magnetic resonance apparatus. Multiple repetitions of the sequence of an inversion pulse, an inversion time and a data recording using the magnetic resonance sequence are triggered by a respiratory signal describing the respiratory cycle, each repetition occurring upon fulfillment of a recording criterion. At least one further inversion pulse is emitted in a waiting time between the sequences.
