For easy detection and imaging of even microscopically small pathological
structures bordering blood vessels in a human or animal body, especially
of lymphatic tissue and arteriosclerotic deposits in the blood vessels,
an arrangement and a process are proposed according to which a nuclear
spin tomography device is used to obtain data for locally-resolved
imaging of the magnetic resonance behavior of the atomic nuclei in a
selected field of view in the body, the device being made and programmed
such that the body can be exposed by the device to high frequency and
magnetic field gradient echo pulse sequences that produce magnetization
in the body so that magnetization of a medium that is flowing in at least
one direction in space in the body can be attenuated by dephasing the
spins of the atomic nuclei in the medium, an MR contrast medium being
supplied to the body.
