In a method and a magnetic resonance system to acquire MR data in a predetermined region within an examination subject, a first three-dimensional volume segment is selectively excited with an RF excitation pulse, this first volume segment including the predetermined region and having a first thickness along a first thickness direction. A selective refocusing pulse is activated in order to selectively refocus a second volume segment. The second volume segment likewise includes the predetermined region and has a second thickness along a second thickness direction orthogonal to the first thickness direction. The following sub-steps are implemented repeatedly in succession: a non-selective refocusing pulse is activated. Two phase coding gradients and an additional magnetic field gradient are activated for spatial coding, and the MR data are read out while the additional magnetic field gradient is activated. |
