In a magnetic resonance tomography method and apparatus (MRT), as employed in medicine for examination of patients, for dynamic distortion correction in EPI measurements, image acquisitions are acquired that are adjacent in a periodic/alternating manner differ with regard to phase information, phase coding direction or with regard to the echo time, and based on this difference a field map and/or a displacement map is calculated with which at least one distorted result image is corrected.
