摘要：In a method and magnetic resonance apparatus to reduce distortions in
magnetic resonance diffusion imaging, a magnetic resonance data acquisition system isoperated to acquire magnetic resonance data in a first measurement with a first diffusionweighting, and to acquire magnetic resonance data in a second measurement with asecond, different diffusion weighting. A non-linear, system-specific distortion-correctingfunction is determined on the basis of system-specific information that is specific to saidmagnetic resonance data acquisition system. Correction parameters are calculated tocorrect distortions in subsequently-acquired diffusion-weighted magnetic resonanceimages, based on the data acquired in the first and second measurements with thesystem-specific distortion-correcting function applied thereto. The subsequently-acquired diffusion-weighted magnetic resonance images are corrected using thecorrection parameters to at least reduce distortions therein.
