In a method and magnetic resonance apparatus for acquisition and
processing of a series of temporally successive image data sets of the
series of temporally successive image data sets is acquired by magnetic
resonance technology, wherein k-space image data corresponding to each
image data set are acquired, and for each image data set in the series, a
determination is made, in at least one first part of that image data set,
of a measure that characterizes a global image intensity value of that
image data set. At least one second part of the image data sets is
corrected using the determined measures and/or the determined measures
are used in an evaluation of at least one third part of the image data
sets. A temporal change of the global image intensity value in the series
of temporally successive image data sets is compensated or taken into
account in this manner.
