Abstract:
In a method and apparatus for the creation of an MR image of a vascular structure of an examination region, the spins in the examination region are saturated by the irradiation of at least one RF saturation signal, which delivers a lower signal intensity as spins in a subsequent MR signal recording for the creation of the MR angiographic image, which flow through at least one blood vessel into the examination region, and are not saturated by the RF saturation pulse. Raw data space of the MR angiographic image is read out with a non-Cartesian trajectory in the MR signal acquisition for the creation of the MR angiographic image.
