Abstract

In a method and magnetic resonance (MR) apparatus for echo-planar MR imaging with which MR signals are entered in raw-data space with a zigzag-type trajectory, a sequence of readout gradients and phase-encoding gradients is applied such that a zigzag-type undersampled trajectory in raw-data space is filled, such that with the signal echoes being shifted by up to a quarter of the acquired raw-data space in the direction of the readout axis. Image data are reconstructed using a parallel-imaging reconstruction algorithm that operates on the raw data acquired in the zigzag-type trajectory, based on an interlaced Fourier transform.
