Abstract

In a method for a rapid determination of spatially resolved magnetic resonance relaxation parameters in an area of examination, a preparation pulse is radiated into the area of examination. During the relaxation of the longitudinal magnetization, spatially encoded magnetic resonance signals are acquired at a minimum of two different points in time using a fast magnetic resonance sequence. At each inversion time, an image data record is reconstructed from the magnetic resonance signals, which are elastically registered to each other. From the recorded image data records, values of magnetic resonance relaxation parameters are spatially accurately determined.
