In a method for representation of flow in a magnetic resonance image, a
first magnetic resonance image of an examination subject is acquired,
wherein the flow occurring in the examination subject is not compensated
in a first spatial direction; a second magnetic resonance image is
acquired, wherein the flow occurring in the first spatial direction is
compensated, the phase of the magnetization in each of the first and the
second magnetic resonance images is calculated of the phase difference
between the first phase image and the second phase image, which is
calculated is a measure for the flow along the first spatial direction. A
third magnetic resonance image is acquired, wherein the flow in a second
spatial direction perpendicular to the first spatial direction is not
compensated, and a fourth magnetic resonance image is acquired, wherein
the flow occurring in the second spatial direction is compensated. The
phase in each of the third and fourth magnetic resonance images is
calculated and the phase difference between the third and fourth phase
images is calculated, which is a measure of the flow along the second
spatial direction. A resulting flow velocity vector is calculated by
vectorial addition of both flow components, and is visually represented.
