Abstract: In a magnetic resonance (MR) apparatus and operating method, a first pulse sequence is executed in order to acquire echo signals from a target volume produced by radiation of a radio-frequency (RF) excitation pulse, thereby obtaining an original measurement dataset. A reference measurement dataset is then acquired by executing another pulse sequence immediately after acquisition of the aforementioned echo signals. These steps are repeated until the original measurement dataset has reached a predetermined degree of completeness that is still incomplete according to the Nyquist criterion. The original measurement dataset is then completed using the reference measurement dataset and a parallel acquisition technique.
