In a method for implementing a dynamic magnetic resonance measurement with
contrast agent administration, at least one imaging magnetic resonance
measurement of a subject region is implemented using an inversion
recovery sequence at a first and possibly further points in time after
administration of the contrast agent, to obtain a magnetic resonance
image of the subject region. Immediately before the first and, if used,
the further points in time, a pre-measurement with a magnetic resonance
sequence is implemented wherein the T1 time of a tissue type, or a
substance type that is of no interest in the magnetic resonance image of
the subject region, is determined, and an inversion time TI used for the
following imaging magnetic resonance measurement is calculated as TI=In2
.times.T1.
