Method for recording and reconstructing a four-dimensional dynamic image data set with a magnetic resonance device, magnetic resonance device, computer program and electronically readable data carriers

摘要

Method for recording and reconstructing a four-dimensional dynamic image data set, in particular a perfusion image data set, of an examination region (1) of a patient (2) with a magnetic resonance device (13), wherein a dynamic scan is performed continuously in a radial scan along radial k-space lines (8, 10, Magnetic resonance images from at least part of the magnetic resonance data associated with the k-space lines (8, 10, 12) recorded during the time segment are reconstructed for individual time segments of the recording period comprising the dynamic process, wherein the examination region (1) spatially into a dynamic range (6) in which the dynamic process takes place, and a non-dynamic range (7) outside the dynamic range (6) can be divided, wherein a static image data set is reconstructed from all acquired magnetic resonance data, i the image data are extracted from the magnetic resonance data and the magnetic resonance images of the different time segments are reconstructed from the magnetic resonance data modified in this way, wherein the dynamic image data set is compiled in the dynamic range (6) for the compilation of the dynamic image data set Contents of the magnetic resonance images are used.
