1. A method for rapid determination of spatially resolved magnetic resonance (MR) relaxation parameters in an examination region, comprising: operating a magnetic resonance data acquisition unit to radiate a radio-frequency preparation pulse into an examination area of a subject in the data acquisition unit, thereby producing relaxation of longitude in all magnetization of nuclear spins in the examination area; during the relaxation of the longitudinal magnetization, operating said MR data acquisition unit to acquire spatially encoded MR signals originating from said nuclear spins at a minimum of two different inversion times, according to a fast magnetic resonance data acquisition sequence; at any of said inversion times, reconstructing an image data record from the MR signals; in a processor, elastically bringing at least two of said image data records into registration with each other, thereby producing registered image data records; and in said processor, identifying, from the registered image data records, MR relaxation parameters in a spatially correct relationship, and making said MR relaxation parameters available in electronic form at an output of said processor.
